20

The increase of maintenance projects of the device should be notice to all staff. Eye-catching bulletin boards and futures should be a written notice, to prevent misconduct and danger caused by human error. Before the maintenance of electrical equipment, we should switch or remove fuses, break it with circuit. The device should be marked with the date and tags. Before the pipeline maintenance, check the pipe should be no pressure and the valve should be closed. Remove the valve hand wheel or lock with chain. The valve operated by the motor should break up with circuit. All valves should provide notations. Maintenance of gas pipeline should use safety gear. Temporary demolition work platform, rails, etc., should be marked with warning signs to prevent falls and accidents. Use lifting equipment, work does not have to crawl or reach out enough. During maintenance period, all temporary arrangement should return to the original condition, inform other workers the work has concluded. Annex 1 Some common sense of heavy oil usage Heavy oil is crude oil extracted gasoline, diesel heavy residual oil, which is characterized by high molecular weight, high viscosity. The proportion of heavy oil is generally 0.82 to 0.95, in the 10,000 ~ 11,000 kcal / kg or so. The composition is mainly carbon hydrates, with part of another (about 0.1 ~ 4%) of sulfur and traces of inorganic compounds 1. Variety features It also known as heavy fuel oil, residual oil, the dark brown fuel viscous liquid, medium viscosity, fuel performance, heat large. Use for boiler fuel, good for atomization, full of fuel, coke and ash less corrosive. Higher flash point, safe for storage and usage. Fuel oil is refined out of crude oil in oil, widely used in ship boiler fuel, heating fuel, metallurgical furnaces and other industrial furnace fuels. Mainly by cracking fuel oil residue from oil and oil made from straight-run residues, which is characterized by high viscosity, containing non-hydrocarbon compounds, resin and asphalting and more. The main technical indicators of fuel oil viscosity, sulfur content, flash point, water, ash, and mechanical impurities. 1、Viscosity: Viscosity is the most important performance index of fuel oil, fuel oil level is the main basis for classification. It is a measure of liquidity resistance capability, its size, said fuel oil fluidity, easy to pump and ease of atomization performance is good or bad. More commonly used domestic and 40 ℃ Viscosity (distillate type fuel oil) and 100 ℃ Viscosity (residual type fuel oil). Fuel oil in China in the past the industry standard with a viscosity (80 ℃, 100 ℃) as a quality control index, kinematic viscosity at 80 ℃ divided by grade. Oil kinematic viscosity is the oil dynamic viscosity and density ratios. Kinematic viscosity of the units is Stokes, That Stokes, called Sri Lanka. When the fluid dynamic viscosity as a park, when the density of 1g/cm3 dynamic viscosity of 1 stokes. CST is an abbreviation Centistokes means determined here, that a one per cent of Stokes.

21

2、 the sulfur content. The sulfur content of fuel oil can cause excessive corrosion of metal equipment and environmental pollution. According to the level of sulfur content, can be classified as high sulfur fuel oil, sulfur and low sulfur fuel oil. 3、 flash point. Involving the use of safety indicators, flash point is too low which will bring fire hazards. 4、water. The presence of moisture will affect the fuel's freezing point, with increasing water content, pour point fuel oil increased gradually. In addition, the water will also affect the combustion properties of fuel oil machinery, may cause the furnace flame, shutdown accident. 5、ash. Ash remaining after burning the part cannot be burned, especially catalytic cracking cycle oil and slurry oil mixed with fuel oil, the Si-Al catalyst powder makes pumps, valves and accelerated wear. In addition, the ash will be covered in the boiler-heating surface, so heat transfer of deterioration. 6、mechanical impurities. Mechanical impurities clog the filter, causing pump wear and fuel injector plug, affecting the normal combustion. Second, the classification of fuel oil Fuel oil as the oil refining process in the final variety, quality control has a strong specificity. The formation of the final fuel products are crude oil varieties, processing techniques, processing depth, and many other factors. According to different standards, fuel oil can look Category: 1、according to whether the formation of the factory goods, fuel and fuel oil can be divided into goods for personal use fuel oil. Fuel means goods of goods shipped form part of the fuel; own fuel for refineries that produce raw materials or fuel without the formation of commodity sectors in the factory fuel oil. 2、according to the machining process, fuel oil, heavy oil can be divided into pressure, decompression of heavy oil, heavy oil catalytic heavy oil and mix. Atmospheric pressure of heavy oil that refineries out of heavy oil distillation unit; decompression means heavy oil refinery vacuum distillation unit out of heavy oil; catalytic heavy oil that refineries, fractionation of the heavy oil cracking unit (known as slurry); mixed heavy oil generally that decompression of heavy oil and heavy oil catalytic mixture. 3、according to use fuel oil can be divided into marine fuel oil and furnace fuel oil (heavy oil) and other fuel oil. Third, the current domestic situation 1、 recent years, domestic oil prices get higher. Lots of heavy oil in the market do not meet national standards, with excessive moisture, excessive moisture can affect the success rate of ignition, combustion caused outages also the quality of the fire phenomenon, take a bit of heavy oil on the newspaper, burning with a lighter point, if the water would be to burn more or issued Zizi's voice. Then heavy oil is good for dehydration. 2、the so-called the "burn oil" is a coal tar, chemical oil, blended oil, a pungent smell unpleasant, serious corrosion. The burners on the seal, oil pump, nozzle, oil gun, air valve, heater with serious injuries. Reduce life circle greatly. Therefore, it shall prohibit. 3、the usage of heavy oil and light oil can not have chemical reaction, because in 3 minutes before the end of combustion with a light oil purging channel, to prevent the solidification of heavy oil in the pipeline, the impact of the second use. If the heavy oil and light oil in the chemical reaction of heavy oil pipelines cannot be wash out, and even blocked pipe. We can put a little light oil and heavy oil in a plastic disposable cups, stirring gently with a tool which. If there is something very sticky, like produce, cannot use this light oil. Should be change for other things a kind of light oil; if the light oil to heavy oil completely dissolved, and just the light oil can be used.
