APPENDIX-I
DETERMINATION OF GROSS ENERGY BY USING BOMB
CALORIMETER
Principle:
The gross energy is the amount of heat produced from unit feed when it is completely burnt down to its ultimate oxidation products (CO2 and H2O).
The feed is burnt is a closed container (Bomb calorimeter) and heat produced from it is measured (AOAC, 1995).
Procedure:
1. Filling the bomb: a) Press the material (feed or excreta) into a tablet weighing 0.5 – 1.0g.
b) Weigh the material, wrap it in weighted cigarette paper and secure with
20-cm long thread of uniform thickness.
c) Connect a 10-cm platinum wire of stainless steel wire to the two
electrodes of the bomb.
d) Place the tablet in the crucible and tie the thread to platinum wire to
carry the flame to the tablet in the crucible.
e) Add about 10ml of distilled water to the bomb.
f) Put the assembly in the bomb, tighten the cap and fill oxygen into the
bomb through its inlet value up to 25-lbs. Pressure per square inch.
2. Adjustment of water temperature in the pail:
Add 2000 ml of distilled water to the pail and keep it in proper position in the outer jacket. Keep the temperature of the outer jacket 5-60 F higher than
the water taken in the pail. 3. Assembling the calorimeter:
a) Place the bomb in the pail and connect with mains of the switch box.
b) Place the stir, thermometer and lid of the calorimeter in their proper
position.
4. Ignition: a) Switch on the stirrer and record the initial temperature after about five
minutes.
b) Ignite the bomb by pressing the push button for 3-4 seconds.
c) Record the final temperature after it is constant for 2-3 minutes.
5. Dissembling the calorimeter: a) Remove the connecting wires, thermometer, stirrer and covering lids. Take
out the bomb and release slowly the gas pressure inside the bomb.
b) Open the bomb, wash all interior surfaces with a jet of distilled water.
c) Collect the washings in 250-ml beaker for estimation of H2SO4 and HNO3
formed form sulphur and nitrogen present in the test sample.
6. Measurement of heat of combination
Calculate heat of combustion from the rise in temperature and water equivalent (mentioned below). Correct it for the formation of acids.
7. Correction for the acid formation:
a) Boil the washings collected in the beaker.
b) Cool and titrate against N/10 barium hydroxide using phenolphthalein
indicator.
c) Add to it 20ml N/10 sodium carbonate solution and boil.
d) Cool the contents filter and wash with hot distilled water (2-3 washings).
e) Titrate the washings against N/10 HCL using methyl orange indicator.
Calculate the heat liberated by H2SO4 and HNO3 using the following factors: 1ml N/10 Ba (OH)2 = 3.60 cal.
1 ml N/10 Na2 CO3 = 1.43 cal.
8. Determination of water equivalent: Use benzoic acid (dried over P2O5) which is a standard material having heat of combustion 6319 cal/g. Compute water equivalent of the calorimeter from the
following equation: HM + C1 + C2 + C3 W = T
Where,
W = Water equivalent of calorimeter in calories / 0 F H = Heat of combustion of standard benzoic acid in cal/g (6319)
M = Weight of benzoic acid in grams T = Rise in temperature of water of the pail
C1 and C2 = Correction for heat combustion (cal) of H2SO4 and HNO3 respectively.
C3 = Heat of combustion of used wire, paper and thread. (Heat of combustion of paper, thread and fuse wire may be taken as 3234 cal/g, 3962
cal/g and 1400 cal/g, respectively).
Calculations
T x W – (C1 + C2 + C3) Gross heat of combustion (cal/g) = M
Where,
T = Rise in temperature W = Water equivalent
M = Weight of substance
