The ultimate and proximate analysis of the fuel used for CFD modelling purposes is shown in Table 1 along with the fuel particle size distribution. The actual plant fires the fuel at a 99 % maximum continuous rating (MCR) with an excess air ratio of %.As the plant turns down from full load the excess ratio is increased to ensure sufficient air and fuel mixing in the furnace.

The most important concern regarding the use of coal combustion in transient processes, as encountered in reheating furnaces, is the justifiable compromise between computational expense and accuracy. Further, to the authors' knowledge, very few works have been reported for simulation with pusher type reheating furnaces [19].

A pulverized coalfired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox.. The basic idea of a firing system using pulverised fuel is to use the whole volume of the furnace for the combustion of solid fuels.
