The world''s relative dependence on coal does not mean that the role of coal burning in global climate change will continue unchecked. A variety of options, referred to as "Clean Coal Technologies", are being researched and implemented throughout the world, with South Africa and Eskom making significant contributions to this field.
Abstract. Many thermal power generation plants rely on combustion of pulverised coal carried out in large furnaces. Design and improvement of these furnaces can be effectively assisted by using numerical modelling with Computational Fluid Dynamics (CFD) techniques to develop a detailed picture of the conditions within the furnace, and the effect of operating conditions, coal type, and furnace ...

Pulverized Coal Burning System. Coal is pulverized or ground to the size of a fine grain (powdered coal or coal dust), mixed with air and burned in the flue gas flow. Principle: Coal is pulverized before firing for achieving a stable and efficient combustion. If the coal is made fine enough, it will burn almost as easily and efficiently as a gas.
Integrated Gasification Combined Cycle (IGCC) An alternative to achieving efficiency improvements in conventional pulverised coalfired power stations is through the use of gasification technology. IGCC plants use a gasifier to convert coal (or other carbonbased materials) to syngas, which drives a combined cycle turbine.
Fluidized bed combustion (FBC) is a combustion technology used to burn solid fuels.. In its most basic form, fuel particles are suspended in a hot, bubbling fluidity bed of ash and other particulate materials (sand, limestone etc.) through which jets of air are blown to provide the oxygen required for combustion or gasification.
The coal, oxygen and if required a moderator (steam) as well as support fuel (methane) is fed to the burner which can be situated at the top or bottom of the gasifier. A part of the pulverised coal is burnt with oxygen thereby producing the required heat for the endothermic gasification reaction.
Reactivity analysis of pulverised coal in O 2 /N 2 /CO 2 environments was carried out using thermo‐gravimetric method. At all temperature ranges, coal combustion in O 2 /CO 2 and O 2 /N 2 environments using equivalent oxygen concentrations was almost similar. However, when oxygen concentration increased the coal burning rate also increased thus reducing the burnout time and net .
This is what is special in a coal fired power plant, especially large thermal power plants. Burning the coal in the combustion process to release the energy in the fuel. Why Pulverizing ? The basic requirement of coal combustion is that all the carbon particles in coal should get sufficient air to burn and release the heat.
