摘要

分布式生物质原料的处理具有转化效率高、低排放、缓解运输压力等显著特点。基于热化学平衡的原理

本文对一种生物质原料气化联产系统进行了研究

建立了系统模型

包括气化炉装置、内燃机和溴化锂制冷机组

并对模型进行了验证。通过分析系统性能发现:合成气低位热值随着空气当量比的增加由8.26 MJ/m~3降至3.12 MJ/m~3;随需求发电量的增加

生物质原料的消耗量由7.5 kg/h增加到15.6 kg/h

制冷量和制热量分别由5.24、1.8 kW升至11.7、2.73 kW

系统的一次能源利用率、运行成本降低率和CO_2气体减排率分别从15.5%、23.7%、68.7%升至24.3%、51.5%、80.1%。该研究成果对于城市分布式生物质能源化处理具有一定的参考意义。

Abstract

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.
