Gas Fuel Rotary Kiln Use Coal Gas, Liquefied Petroleum

The calorific value of natural gas is not as high as that of liquefied petroleum gas, but in some countries with abundant natural gas reserves, cement rotary kilns used in cement production mostly use natural gas as the main fuel. Natural gas can replace oil fuel and raw coal as the main fuel of rotary kiln.

Replacing coal by natural gas in kilns - Page 1 of 1

Re: Replacing coal by natural gas in kilns. There are at least 2 reasons why cement kilns fired with natural gas are less productive than those fired with solid fuels: (i) the combustion product gas volume is higher with natural gas due to its higher hydrogen content, therefore the effective capacity of the induced draft fan of the kiln is reduced, and (ii) the emissivity of a gas flame is ...
