while the coal is burning what gas is produced - .

When coal is burnt,we get three main constituents out of it- coal tar,coke and coal gas. So here,Coal Gas is produced due to the burning of coal. Coal gas contains a mixture of gases such as ethylene, hydrogen, carbon monoxide, methane etc. It acts as a fuel due to high calorific value of these gases, when burned. Hope This Helped You :)

1.7 Lignite Combustion - US EPA

Coals are classified by rank according to their progressive alteration in the natural metamorphosis from lignite to anthracite. Coal rank depends on the volatile matter, fixed carbon, inherent moisture, and oxygen, although no one parameter defines rank. Typically coal rank increases as the amount of fixed carbon increases and the amount of volatile matter decreases. Lignite is a coal in the ...

Can You Burn Coal In A Wood Burning Stove? | .

If you use coal inside a wood burning stove then it won't burn properly due to incomplete combustion. Inadequate combustion of fuel is bad for both you and your stove. Fuel that doesn't burn properly will produce more smoke as a result. Larger quantities of creosote can also be produced, which lines the inside of your chimney or flue and requires you to have it swept more often. I've ...
