Q. 18 C4.0( 6 Votes )
The calorific value and ignition temperature of fuel A are 55 kJ/g and 80oC, respectively. These values for fuel B are 80 kJ/g and 10°C, respectively. On burning, the fuel A produces CO2 and H2O while the fuel B produces CO2, CO and SO2. Give three points of relative advantages and disadvantages of these two fuels.
Answer :
Fuel A:
Advantages:
No toxic gases are released.
Proper ignition temperature of around 80°C.
Disadvantages:
It has a lower calorific value of 55kJ/g.
Fuel B:
Advantages:
It has a high calorific value of 80kJ/g.
Disadvantages:
It releases toxic gases like CO and SO2.
It has a very low ignition temperature of 10°C.
