What Is the Chemical Equation for the Combustion of Coal

The chemical equation for the combustion of coal is C + O2 = CO2. In this equation C represents the carbon in the coal which reacts with air represented by O2 to form carbon dioxide or CO2. When coal combustion occurs in an environment low on oxygen the equation C + CO2 = 2CO may result.

2 Gasification of Coal University Of Maryland

Conversion of coal from its solid form to a gaseous fuel (or gaseous chemical) is widely practiced today. During earlier years (1920–1940) coal gasification was being employed to produce manufactured gas in hundreds of plants worldwide and such plants were called manufactured gas plants (MGPs).

A mathematical model of gas flow during coal outburst

The energy of elastic deformations stored in the coal microstructure activates chemical reactions to tilt the energy balance in a coal–gas system. Based on this concept a mathematical model of a gas flow in the coal where porosity and permeability are changed due to chemical reactions has been developed.
