Numerical Simulation Study on Collaborative Disposal of Agricultural and Forestry Wastes by Fluidized Bed Boilers

Numerical simulation of agricultural and forestry waste blended firing in a 75 t/h circulating fluidized bed boiler was conducted. The correctness and reliability of the simulation model were verified by the experimental data through comparison. The effects of blending conditions and boiler operating parameters on combustion characteristics in the furnace, pollutant emission and furnace wear were analyzed thoroughly. The results show that the combustion characteristics are improved by low blending ratio of the agricultural-forestry waste and high primary air ratio. While high blending ratio of the agricultural-forestry waste will reduce pollutant emission.
