Combustion of pulverized coal fuel in a spray vortex burner

Abstract

The process of combined combustion of pulverized coal and liquid hydrocarbon fuels has been studied. A vortex oil-steam burner was developed and modernized, and it was adapted to experiments on combustion in a closed combustion chamber of a low-power household hot-water boiler. The heat release and gas composition were measured during the co-combustion of pulverized coal and liquid hydrocarbon fuels with the supply of superheated steam to the combustion chamber. It is shown that the combustion method under study is characterized by high combustion efficiency and low levels of harmful emissions.
