A system and method for combustion of pulverized coal in small and medium boilers. The system includes a combustion chamber (101) comprising an internal chamber and an external chamber separated by an inner wall (103) and connected at the apex of the combustion chamber, one or more nozzles (105), a primary air pumping mechanism, and a secondary air pumping mechanism for supplying additional combustion air into the combustion chamber. During the combustion of the pulverized solid fuel, the primary and secondary air pumping mechanisms creat a reflux of fuel-air flow within the combustion chamber, improving the overall efficiency of combustion of the fuel. |
