Exergy Analysis of A Biomass Gasification System
摘要
Abstract
Based on the latest progress of ecological thermodynamics,the exergy theory was firstly used to study biomass gasification system.With a 20 MW biomass gasification gas-steam combined cycle power generation project in Yancheng City,Jiangsu Province as study case,the ecological environment benefits was comprehensively analyzed.The exergy-based indicators of the biomass gasification system was calculated and compared with other renewable exergy conversion systems including wind power generation system,solar thermal power generation system,corn-ethanol production system and biogas system.The results showed that the total exergy inputs of the biomass gasification system is calculated to be 1.04E + 15 Jc/a,and exergy conversion rate is 2.64 Jc/J.Labor inputs are the main contributor to total exergy inputs,taking up 86.04％.Similar to other renewable exergy conversion systems,biomass gasification system is mainly supported by exergy purchased from outside.But it has advantages in sustainable development and eco-environmental benefits.关键词
