4.It should have moderate rate of combustion.
5.Combustion should be easily controllable i.e., combustion of fuel should be easy to start or stop as and when required.
(b)
The calorific value of LPG is 55000KJ/Kg means when 1Kg of LPG is burned completely then 55000 KJ of heat energy is produced. ... This means that burning of a given amount of LPG will produce much more heat than burning the same amount of cow-dung cakes or coal.
