Description
Summary:The thermal conversion of solid fuel is considered (for the example of biomass), with assessment of the yield of volatiles and coke residue. The optimal temperature range for its pyrolysis (the range corresponding to maximum heat of combustion of the gases per unit mass of the initial product) is identified. The influence of steam and air flow rates on the gasification products is studied. A system for the generation of thermal and electrical energy in the steam-gas cycle is proposed, with a biomass gasification unit. The energy loads of a population center are calculated, with engineering and economic assessment of the steam-gas cycle. Biomass-based cycles are compared, from the perspective of the energy efficiency of a cogeneration system.
