摘要：
Experiment of co-combustion of coal and biomass pellet on a 7 MW chain stoker boiler was carried out and the performance of the chain boiler was tested under 5 mixing ratios of biomass pellet to coal, 0%, 10%, 25%, 20% and 30%. The results of experiment showed when mixing ratio of biomass pellet was different, the boiler could work safely and stably, the boiler's fuel consumption reduced and sulfur dioxide emissions of the boiler decreased significantly. When the biomass pellet mixed, the coal was easier to burn out, the carbon in ash residue of coal boiler and heat loss from solid incomplete combustion also decreased, enhanced the overall operating efficiency of the boiler.
