The distributed biomass feedstock gasification treatment has significant characteristics such as high conversion efficiency

low emissions and relieving urban transportation problems. This paper studies a kind of biomass feedstock gasification cogeneration system

and the models of gasifier

internal combustion engine

and double-effect lithium bromide unit are established and verified based on the principle of thermochemical balance. Through performance analysis of the system

it can be found that

the low heating value of syngas decreases from 8.26 MJ/m~3 to 3.12 MJ/m~3 as the air equivalent ratio increases. As the demand for power generation increases

the consumption of biomass feedstock increases from 7.5 kg/h to 15.6 kg/h

the cooling capacity and heating capacity increases from 5.24 kW and 1.8 kW to 11.7 kW and 2.73 kW

respectively

and the primary energy utilization rate

the reduction rate of operating cost and the reduction rate of CO_2 gas increases from 15.5%

23.7% and 68.7% to 24.3%

51.5% and 80.1%

respectively. The research of this paper has certain reference significance for the distributed biomass feedstock treatment.
