The slag generated from coal gasification process contains a certain amount of heat value

reasonable utilization of the slag can not only reduce the operating cost of coal-fired power generation enterprises

but also effectively solve the environmental pollution problems. To deepen the utilization of gasified slag

the gasified slag and a coal commonly used in a thermal power generation enterprise were blended to investigate the co-combustion characteristics and economic feasibility

through ash composition analysis

ash fusibility characteristics analysis combustion characteristics analysis. The results show that

the gasified slag can be use after drying. When the blending ratio of the gasified slag was less than 30%

the spherical temperature of the mixed fuel was higher than that of the boiler design coal

the boiler could run safely theoretically. With the increase of the blending ratio of the gasified slag

the combustion characteristic parameters such as ignition temperature

temperature of the maximum combustion rate and burnout temperature all decreased

indicating that increasing the gasified slag proportion could enhance the combustion efficiency of the mixture fuel. However

the reaction intensity and the maximum combustion rate reduced.
