Mathematical Modelling of the Pulverised Coal Preparation for Combustion Using Plasma

This paper studies the physics of pulverised coal preparation within a plasma burner (muffle). Compared with conventional coal burners, in this concept a proportion of the pulverised coal and air mixture is diverted from the main flow and heated by a low temperature air plasma flame. The plasma flame, as a heat source and oxidant, provides a high temperature radical-rich environment wherein complete volatiles evolution and partial gasification of the carbon residual takes place. This highly reactive fuel fraction, entering the combustion chamber of the furnace, mixes with and ignites the main stream of pulverised coal and air. The resulting flame does not require any additional heat source or any additional fuel to maintain the combustion stability.
