Experimental Study on the Mixed Combustion Characteristics of Biomass and Municipal Solid Waste

In the light of the shortcomings of the power generation method by burning a mixture of municipal solid waste and biomass resulting in inferior economic benefits,set up was a biomass and municipal solid waste mixed combustion test system with the influence of the main controllable parameters during the design and operation of the system on the furnace temperature and fuel combustion efficiency being mesured. It has been found that the furnace temperature will rise with an increase of the primary air rate and dilution/mixing mass percentage content,and decrease with an increase of the excess air ratio. The fuel combustion efficiency will increase with the primary air rate and dilution/mixing mass percentage content. It will increase first and then decrease with an increase of excess air ratio. When the excess air ratio is set at 1.7,dilution/mixing mass percentage content is 15% and the primary air rate is 75%,the furnace temperature will reach 880 ℃ with the fuel combustion efficiency being assessed at 97.4%.
