Abstract

Abstract

Combustion tests of a sludge coal water slurry (S-CWS) and Datong bituminous coal water slurry (Datong bituminous CWS) were performed in a 3.2 MW horizontal furnace to investigate the industrial application feasibility of S-CWS. The properties of ignition, combustion, slagging and pollutant emission were analyzed respectively. The results indicate that S-CWS with sludge mass ratio of 10% can be easily fired and combusted stably. With better burning and slagging properties than Datong bituminous CWS, S-CWS produces ample flame in uniform distribution. The addition of sludge results in high concentrations of sulfur dioxide and nitrogen oxides in flue gas, which can be relieved by adding desulfurizing agents in practice. Generally, it is satisfactory to burn S-CWS in the 3.2 MW furnace, offering a new feasible method of sludge disposal.
