ABSTRACT
A parametric study intended to determine optimum burning parameters of locally available coal from mines in
Darra Adam Khel is being reported. The coal samples were tested in a cyclone combustor using the pulverized coal
combustion technique. Effect of mesh size, primary and secondary air velocity at various air fuel ratios was investigated
to quantify the combustion performance by measuring the furnace temperature. Mesh size 200 was found to
be readily combustible within the operating ranges, while tight control of the operating parameters was required
to combust coal at mesh size 150. Optimum ranges of primary air and Air-Fuel Ratio are suggested for effective
combustion. The study will help in effective utilization of indigenous coal reserves of Pakistan.
