The following data are obtained in a Bomb Calorimeter experiment.

Weight of coal burnt = 0.95g

Weight of water taken = 700g

Water equivalent of calorimeter = 2000g

Increase in temperature = 2.480C

Acid correction = 60.0cal

Cooling correction = 0.02oC

Fuse wire correction = 10.0cal

Latent heat of condensation = 587 cal/g

Calculate the GCV and NCV of the fuel if the fuel contains 92% of C. 5% of H and 3% of

ash.

2. On burning 0.72g of a solid fuel in a Bomb calorimeter, the temperature of 250g of water is

increased from 27.3oC to 29.1oC. If the water equivalent is 150g, calculate the HCV of the fuel.

3. A sample of coal was found to have the following percentage composition. C= 75%, H= 5.2%,

O= 12%, N= 3.2% and ash =4.5%. Calculate the minimum air required for complete combustion

of 1 kg of coal.

4. In an experiment in a Bomb calorimeter, a solid fuel of 0.90g is burnt. It is observed that

increase of temperature is 3.8oC of 4000g of water. The fuel contains 1% of H. calculate the

HCV and LCV value (equivalent weight of water = 385g and latent heat of steam = 587 cal/g)
