Coal immemorial plants into. "Carboniferous" dating back 300 million years ago, the Earth's climate is warm and humid, lush plant growth. Especially marshes, grew bright with tall trees. Due to changes in the crust, these plants are buried in the ground, after a long era, under tremendous pressure, temperature, and the role of bacteria decomposing deterioration when some gases, such as CO, CO2, CH4, H2O volatile become Flammability carbon-rich rock, of this combustible rock is coal. The coal-forming process, called coalification. This process is very long, and have at least a few hundred million years. These plants initially become peat carbon is about 59%; culminating in the lignite, the carbon content of about 69%; then into bituminous coal, the carbon content of 82%; finally turned anthracite carbon content of up to about 95%. Therefore, we say, peat, lignite, bituminous coal and anthracite are the remains of ancient plants in the coal-forming process at different stages of the product.

Coal combustion in the grate of the tunnel kiln in the inverted flame kiln or coal burning, it is the ignition, burning, burn the three phases are mutually staggered. For example, the Xintian into the coal is in the ignition stage, below it is now in the stage of combustion of the coal, the new coal fire the heat required is in the stage of combustion of the coal supplied to the heat released by this, in this layer is at below the coal to the combustion stage, is added to the previous batch of coal, has entered the burnout stage. Over a period of time, and added into a number of new coal. Began its coal fire stage, the original ignition phase of coal into the combustion stage, the original coal burning phase into the burnout stage, while the original burnout stage already become ash. Coal grate is such a time, inter-related to burning.
