How did the gas come out?
Here let us look at some of the commonly used methods of gas production, to see how the gas is made of it. We usually eat most of the food cooked, put it in a pot, cover, fire underneath the pot heating, put the cooked food. The coking gas and this is very similar, just "the pot" is not food, but put on coal. Is usually the first to break coal, washed, and then according to a certain formula will mix different kinds of coal, into the refractory brick for special "pot" - coke oven. Coke oven furnace is just like a flat box, the box at each end of a door, is like the pot lid, in order to produce coke. Coal is sealed in the furnace, and the outside of the air isolation, both sides of the box close to the fire, the fire path through the common gas to burn heating, so that the furnace temperature of the raw coal gradually increased.
There are many ways to make gas, because the method is different, the gas is not the same. For example: coke oven gas, producer gas, water gas, oil and gas, artificial gas, blast furnace gas, cracking gas and so on many kinds.
Another common method is the use of gas, gas generator manufacturing, coal ignition and combustion in furnace, if we pass the bottom of the air fire restrictions, in the furnace of coal will not get enough oxygen, the carbon content in coal is not fully oxidized, resulting in gas - a large number of carbon monoxide. When the gas is produced by the gasification method, the gas discharged from the exhaust pipe of the top of the furnace is mainly composed of carbon monoxide, carbon dioxide and nitrogen.
