Abstract
On a one-dimensional flame furnace and ignition furnace, blend burning tests for Shenhun coal and high sulfur content coal from Chongqing energy (Nengtou coal) were carried out. The influence of mixing proportion, coal fineness and operation oxygen content on ignition temperature, burn-out rate, slagging and pollutant mission of the blended coals were studied. The results show that, with an increase in mixing proportion of the Nengtou coal, the ignition temperature of the mixed fuel increased, the burn-out rate and slagging tendency decreased, and the emission concentration of NOx and SO2 rose substantially. The field blended coal combustion experiment in the power plant boiler indicated that, the boiler efficiency and slagging characteristics had no obvious change, while the NOx emission concentration increased a little, the SO2 concentration increased significantly, leading to an increase in the operation cost.关键词
