Question

The calorific value and ignition temperature of fuel A are 55 kJ/g and 80°C, 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 and disadvantages of these two fuels.

Solution

Advantages of fuel 'A'.
       1.It has a moderate ignition temperature.
       2. It does not produce any harmful gases.

      Disadvantage:
       1. It has a low calorific value and produces less heat per unit mass.

     Advantage of fuel 'B':
       1. It has a high calorific value and hence generates more heat.

     Disadvantages:
       1. It has a very low ignition temperature and hence is unsafe to use.
       2. It produces harmful gases, such as CO and SO₂_.
