【摘要】：文章提出了一种基于下吸式固定床气化炉的新型生物质冷、热、电联供(CCHP)系统,以整个系统为研究对象,通过系统模型的建立与计算,研究了气化子系统的气化特性以及系统在全工况条件下的能量输出特性、运行经济特性、二氧化碳排放特性。研究结果表明:生物质气内燃机的功率明显低于天然气内燃机的功率,基于生物质的CCHP系统不能实现满负荷运转,系统输出最大电量时对应的内燃机部分负荷率(PLR)为75%;基于生物质的CCHP系统的一次能源利用率与效率较低,一次能源利用率为11.52%~40.68%,效率为11.52%~18.60%;基于生物质的CCHP系统的运行经济特性和二氧化碳排放特性非常突出,最大运行费用节约率为64.71%,二氧化碳减排率为57.40%~82.17%。
[Abstract]:This paper presents a novel based on biomass downdraft fixed bed gasifier cold, heat, electricity cogeneration (CCHP) system, the whole system as the research object, through the establishment and calculation of the system model, the energy output characteristic of gasification characteristics of the gasification system and in all conditions, economic operation characteristics of carbon dioxide emission characteristics. The results show that: the biomass power gas engine was significantly lower than the power of natural gas engine, CCHP system can not achieve full load operation of biomass based on the maximum output power of the internal combustion engine part load rate was 75% (PLR); a CCHP system of biomass energy utilization and efficiency based on lower primary energy utilization rate is 11.52%~40.68%, the efficiency for the 11.52%~18.60%; CCHP the operating characteristics of the economic system of biomass and carbon dioxide emissions with outstanding characteristics based on the maximum The operation cost saving rate is 64.71% and the carbon dioxide emission reduction rate is 57.40%~82.17%.
