BOILER SYSTEM CONTROL VALUES PROGRAMMAKE UP WATERUse a softener where possible to prevent scale deposits from forming in the boiler

SOFTENER ( Record all test values and make up gallons from water meter)Maintain softener to produce hardness levels of ‘ Hardness < 0.5 ppm as CaCo3 (Water Test will show BLUE) - Normal expected condition‘ Hardness > 0.5 ppm as CaCo3 (Water Test will show RED ) When Water Test show RED MANUALLY regenerate the softener.If hardness leakage persists after softener is regenerated, check the following1. Check salt level daily in the brine tank. Maintain salt level 3/4 full at all times2. Check to see if softener valves are functioning properly, and no hard water by pass is open3. Check softener resin. If the resin is dirty use a resin cleaner. If the resin is low add. If the resin is

more than 10 years old have the resin replaced.4. If Hardness persist call your Water Treatment Supplier and have softener serviced immediately

FEED WATER# Maintain hardness level < 0.5 ppm. BLUE COLOUR. EXPECTED. If RED COLOUR check

softener and condensate for hardness. Record Feed water TDS, Hardness & Tank Temp..

BOILER WATER Sample of boiler water must be at room temperature before testing.‚ Maintain Sulphite levels during normal Boiler Operating Period at 50 - 80 ppm ( 10 - 16 drops). ‚ On Fridays before shutting down for week end raise the sulphite values to 100 ppm ( 20 drops) in

the boiler. This will protect boiler over week end when it is not operating. Note: 1 drop = 5 ppm. If Sulphite value is low increase pump setting / timer. If Sulphite value is high reduce pump setting

‚ If on a Molybdate Program maintain Molybdate value at 100 - 150 ppm in boiler water

‚ Maintain TDS in boiler at 3500 - 4000 MMHOS by controlling boiler blowdown If TDS Value is Lower than 3500 mmhos reduce blowdown. If TDS Value is higher than 4000 mmhos increase blowdown. CONDENSATE‚ Check for Hardness. Maintain values of hardness as BLUE. If water turns RED look for source of

hardness leakage. (Leaking heat exchanger / Hard water by pass)‚ Check TDS in condensate for steam purity. If values are > 60 mmhos inform your water treatment

supplier. ‚ Check pH of condensate by adjusting amine feed to maintain pH around 8.6 - 9 AUTOMATIC BLOWDOWN CONTROLLER ‚ Flush probe daily, using valve below probe.

pH TEST PROCEDURE

When collecting sample for testing condensate pH, please carry out the followingprocedure.

1) Sample should be Cooled to Room Temperature before checking pH

2) The pH meter should be calibrated with pH 7 and pH 10 buffer solution at least once /week.2 B) If using pH Test strip, please dip strip into water sample and match to colour onbox, to arrive at pH.

3) Try to maintain a pH range of 8.6 - 9 in condensate by adding neutralizing amine

4) If pH is lower than 8.6 increase amine feed

5) If pH is higher than 9 reduce amine feed.

6) Monitor condensate TDS . If the sample of condensate TDS is higher than 50 mmhos thenthere is a good possibility, that the condensate is contaminated from poor steam quality.Boiler Water is carry overing with steam. If this is the case reduce TDS in boiler to <4000 mmhos

7) Determine what is causing carry over and rectify. High TDS in boiler or high Alkalinitycould cause carry over.

NOTE: Carryover will cause problems with fouling of Heat exchanger. Low pH will result in condensate piping failures. Higher than 9 pH will result in corrosion of Yellow metals. Eg. Brass valves, copper in system Copper in boiler feed water is dangerous and can cause galvanic pitting on steel boiler tubes.

BOILER CONTROL RECORDS

WATER TREATMENTTo maintain your Boiler in good condition, a Good Water Treatment program is essential.

Your Water Treatment program should be considered just as critical, as operating your car without thenecessary oil changes.

For a good Water Treatment Program to be effective, the following Standard equipment should be partof your system.

EQUIPMENT REQUIRED FOR GOOD CONTROL OF WATER TREATMENT:Duplex Softeners for a 24 hour Operation. Single Softener for 8 hour operation is adequateSoftener Polisher on all Low Volume or Coil Tube BoilersWhere very poor water quality only is available, a Reverse Osmosis unit is recommendedA Dealkalizer or Reverse Osmosis is recommended where the use of neutralizing amines is prohibited. Contact Water Meter to control a Chemical Timer and Chemical Pump.Chemical timers with accumulators. Feed Water Tanks should having a Steam heater. A Deaerator is recommended where very high watermake up occurs.An Automatic Surface Blowdown Controller with needle valve and solenoid or motorized valve

WATER TREATMENT TESTINGThe following water test should be carried out a minimum of once / day / shift.

SOFTENER TEST:This is one of the most essential tests and should be done at least once per day on the preboiler system

Water samples should be taken from the softener and the polisher. A sample should also be taken fromthe Feed Water tank or deaerator. A minimum of three (3) Test areas for Hardness should be monitored.A. Flush sample lines and rinse the sample jar properly before taking a sample.B. Collect the correct sample amount, based on the test procedure used. Sample amount ----- mlsC. Add Hardness Indicator to the sample ----- dropsD. Add Hardness Buffer to the sample ---- dropsE. Sample should turn SEA BLUE , if water is SOFT. If hardness is present , sample will turn REDF. If RED, titrate with appropriate solution, until sample turns BLUE. Record hardness value.G. If Hardness is present, always determine the reason and rectify the problem.

TROUBLE SHOOTING FOR HARDNESS 1. Check if salt level in Brine Tank is LOW. Level should always be 3/4 of Brine Tank 2. Check to see if the salt has bridged in tank due to heat. Add water and break salt up 3. Check to see if Clock Time is correct, alter if not. Make sure Electric power is on softener. 4. Check if the Emergency bypass valve has been left opened. Always keep closed. 5. Check if the Emergency bypass valve, is leaking water. 6. Check if softener drain line is plugged or damaged. Repair if required. 7. Check if the Softener brine line has a kink, preventing brine from getting to the softener resin. 8. Check if the Resin has got fouled with iron. Add a resin cleaner to the brine tank periodically. 9. If hardness test was done on the Feed Tank and soft water was detected at the softener but not in the Feed Tank, then hardness can be coming back with the condensate. Check if cold hard water quenching is occurring. Stop this practice if this is happening. Check if a leaking hard water line is connected to the condensate and rectify immediately.

Duplex SoftenerPolisher

10. Softener needs a Service Technician if problem cannot be corrected. Call immediately for Service. In the event of Hardness Leakage, call your Water Treatment Supplier, and at the same time implement the following procedure. A Increase Boiler Blowdown by reducing Boiler TDS to 1500 mmhos from standard. B. Increase Boiler Dispersant Feed Rate by twice if using. C. The Boiler may require inspection to determine if any damage was caused. (Scale Build up)

BOILER CONDUCTIVITY (TDS) TEST:Check conductivity value in the boiler by following this procedure.I. Flush line and collect a sample of water from the boiler gauge glass

or off the surface blowdown line.II. Cool the sample to room temperature. III. Add sample to hand held conductivity meterIV. Control level to maintain is --------- - ------- mmhos in boiler V. If less than --------- mmhos you are blowing down too muchVI. If higher than -------- mmhos you need to increase blowdown.VII. If an Automatic Blowdown Controller is in use, check unit to see if it needs calibrating. Hit reset button always before calibrating. VIII. If values are consistently low, it is possible that you may have a

leaking solenoid valve or valve on the boiler, leaking water out of theboiler. Check blowdown pipes for heat loss.

IX. If values are high and you do not have an Automatic BlowdownController, then consider investing in an Automatic BlowdownUnit.

X. If values are high and you have an Automatic BlowdownController, then check if the solenoid valve has failed or needlevalve is plugged.

XI. The automatic blowdown probe should be flushed daily for (3)three seconds as shown on the picture.

XII. Set Automatic Control as shown. Calibrate control weekly.

SULPHITE TEST: If using this product.To protect the boiler and feed water tank from oxygen corrosion, the use of sodium sulphite isa common treatment program.A. Flush and collect a sample of water from the boiler gauge glass, or off the surface blowdown line.B. Cool the sample enough for safe handling. C. Measure appropriate sample, based on test procedure into a jar . Sample size ---- mlsD. Add 1 scoop of Acid Powder Starch reagent to sample.E. Titrate, using Potassium Iodide Iodate solution until sample turns BLUE. F. The value to maintain is - ppm in the boiler. ( ---- to ---- drops depending on size of sample)G. Less than ----- ppm (---- drops), in boiler, increase feed rate of chemical pump or increase chemical timer setting.

H. Higher > ---- ppm (---- drops) in the boiler, reduce feed rate of chemical pump or reduce timersetting.

I. If the Feed Water Tank is cold < 180 F, the feed rate of the chemical will be higher. IncreaseFeed Water temperature of Tank to 180 F, to reduce chemical usage.

J. If pH of Feed Water is < 8.4, the consumption of sulphite will be increased. Adjust pH in feedwater tank, to achieve a level higher than 8.4 to reduce chemical usage & protect the boiler.

K. If Boilers are not operating 24 hours / day, 7 days / week you may have to increase the feed rateof sulphite, to achieve protection of the boiler during idle periods, where the boiler loses heat.Sodium Sulphite consumption is temperature dependant and will be consumed, as thetemperature in the water gets colder. If you are having problems maintaining control, discuss thiswith your Water Treatment Supplier for other options available.

TROUBLE SHOOTING CHEMICAL LEVELS 1 If chemical is low, check to see if drum is empty.2 If chemical is low, check to see if chemical pump has lost prime. Prime pump, If required3 If pump continues to loose prime, check pump Check valves and replace if required.4 If chemical is low, check if pump strainer is plugged. If required clean strainer.5 If chemical is low, adjust chemical pump timer or chemical pump frequency by increasing.6 If chemical value is high, reduce pump stroke or timer setting.7 If chemical value is high, check boiler TDS. If higher than recommended, increase blowdown and leave chemical timer and chemical stroke the same. Monitor TDS and control to range.8 If chemical level is low ,check boiler TDS. If value is low, you are blowing down the boiler too much or have a leaking valve/s etc. Fix leak and correct TDS to recommended range.

MOLYBDATE TEST: If using this productTo protect the boiler and feed water tank from corrosion, the use of special blends of Molybdate areavailable which can overcome many of the problems associated with a sulphite treatment program1. Flush & collect a sample of water from the boiler gauge glass or off the surface blowdown line.2. Add the sample to the test tube provided, and fill to the 5 ml mark3. Add 1 drop of Reagent # 1 to the sample. (Using Jacklyn Reagent)4. Add 3 Drops of Reagent # 3 to the sample. (Using Jacklyn Reagent)5. Place test tube in comparator and compare sample with slide.6. Recommended values to maintain is 100 - 150 ppm 7. Less than 100 ppm, increase feed rate. Higher than 150 ppm , reduce feed of chemical

TROUBLE SHOOTING: Follow same check procedure shown above, with a sulphite program.

pH TEST of CondensateA. Flush and collect a sample of water from the condensateB. Cool sample to room temperatureC. Using pH meter, check pH of sampleD. Control range to maintain is 7.6 - 8.6 pHE. Less than 7.6 pH increase feed rate of amineF. Higher than 8.6 pH reduce feed rate of amine

TROUBLE SHOOTING: Follow same procedure shown above with a sulphite, Item # 1 - 6 only.

NOTE: If you are getting Boiler carryover, you will also get false high pH readings. Carryover of boilerwater will damage a steam system. In addition, you lose energy and contaminate heat exchangers, andprocess. This condition is also dangerous and could cause water hammer and break steam lines. Hardness Test of CondensateFlush and collect sample of condensateFollow same procedure for hardness test, as done on softenersIf hardness is detected, please enforce same strict procedure as discussed with softener test.

Conductivity Test of CondensateFlush and collect sample of condensateCheck conductivity of condensate, to determine steam quality1. Conductivity of condensate should be < 50 mmhos, if good steam quality is occurring. 2. Conductivity > 50 mmhos, please review with your Water Treatment Specialist why this is high.

COPPER PIPING IN CONDENSATE SYSTEMSCopper should not be used in condensate systems. Copper tracing piping, copper heat exchangerbundles, can result in possible galvanic corrosion, occurring in boiler systems.Copper has the potential in steam systems, to corrode at high pH and at low pH. As both of thesepossibilities are common, it is strongly recommended that copper should not be used.If galvanic corrosion occurs, the potential result is pitting on the boiler tubes, resulting in tube failure. Asnormal Water Treatment programs do not address this problem, the risk of failure is high and coppershould be avoided in all equipment in condensate systems.Failure of boiler tubes can result in very expensive repairs and loss in boiler down time.Monitoring copper levels in the feed water will provide indication of possible problems, ASME recommends that copper should be < 0.05 ppm in the Feed water

DISPERSANT FEED :If chemical dispersant is being used separately, control dispersants based on the feed raterecommended.Note: Feed rate will depend on make up, boiler cycles and feed water quality.If feeding dispersants separately, by separate pump, follow same Trouble shooting procedure shown forchemicals.

DEAERATORIf you have a deaerator to mechanically remove oxygen, you will still need to use an oxygen scavenger.The deaerator functions well, operating at a pressure of 5 psig. The storage tank temperature of a

Thermostat

deaerator, should run about 228 F, if the deaerator pressure is 5 psig.In addition, the deaerator must have a vented gas plume, to remove the gasses. This plume should beabout 2 - 3 feet high. It can be observed from outside the building. If the gases are not being ventedproperly, corrosion may occur in the deaerator.

ENERGY SAVING TIPSTo maintain an efficient boiler system, the following should be addressed.1. Insulate all hot exposed areas, such as Feed Tanks, feed water pipe lines, steam lines, hot

exposed areas on the boiler and condensate lines.2. Repair any pipe insulation that has been removed or damaged.3. Have a good Planned Maintenance Program on traps. Trap leaks are one of the biggest steam

energy losses. Repair failed traps immediately.4. A good sign of trap leaks, can be determined if the Feed water tank is venting off high steam

plumes. Also if the boiler feed tank temperature shows higher than 200 F5. Maintain conductivity in boiler at the recommended control range. Low conductivity values means

excessive blowdown and energy loss.6. Reduce Wet Steam by controlling Boiler Blowdown effectively.7. Recover Flash steam or blowdown water and use to pre heat make up feed water, through heat

exchanger8. Carry out Fuel Combustion Test every 6 months.9. Make sure your Burner Technician, has set up your boiler to the maximum achievable air to fuel

combustion ratio, for the best combustion efficiency.10. Return all condensate that can be returned that is not contaminated.11. Monitor water make up regularly, to make sure you are not losing return condensate water. 12. Maintain a scale free boiler, by keeping softeners producing soft water . 13. Do not run higher boiler pressures than required.14. Run boilers sized to Load. Over sized boilers have higher radiation and Purge Losses15. Shut off steam going to areas that are not requiring steam any longer.16. Repair immediately all steam leaks.17. Make sure that the boiler room has adequate air in / out and room

temperatures are in a range not to effect electronic equipment.

BOILER BLOWDOWN TANKBoilers of steam pressure >15 psig, require in Ontario to be blowndown intoa blowdown tank, designed for this operation. In addition the water exitingthe blowdown tank to sewer, needs to be controlled below a specifiedtemperature, based on the local regulations.To do this, boiler blowdown tanks should be outfitted with a temperaturethermostat, to control the exit water temperature to the sewer. Adjustthermostat to suit. This will inject cold city water into the tank. Furthermore,care should be taken to protect drain lines, by making drain lines of tile orsteel construction and not PVC due to the temperatures. PVC drains will fail withhigh heat in a very short time. BLOWDOWN CAUTIONWhen blowing down boilers under pressure, the valves must be opened slowly. Any quick action couldresult in the pipe breaking, resulting in injury or death.In addition, caution should be to have a get away path, in the event of the pipe breaking.Make sure to have a good clear access path all round the boiler, at all times.Follow all TSSA rules and procedures, as they are the Governing Body responsible for the safetyoperation of boilers in Ontario.
