摘要
本文以2MW秸秆简单气化—内燃机发电系统为具体研究对象,建立了基于生命周期分析方法的数学模型和支撑数据库,对系统边界、环境影响指标、决定系统环境性的重要参数进行了讨论。同时,对秸秆气化发电系统进行了生命周期评价,全面分析了秸秆气化发电过程中不同排放物和能源消耗对环境的影响。最后,得出秸秆气化发电是一种环境友好型的能源生产方式,发展秸秆气化发电要注意对其排放物的处理等结论。
Taking the power generation system with simple gasification-internal combustion of 2WM straw as a case study,this paper establishes a general methodological model and a basic database based on the life cycle analysis method,and discusses the system boundary,the index of environmental impact and the important key factors in environmental characteristic of system.And it evaluates the life cycle of straw gasification power generation system,and analyzes the impacts of different emissions and energy consumption on environment in the process of straw gasification power generation.Finally,it draws the conclusion that straw gasification power generation is an friendly environmental energy production,and developing it should pay attention to the treatment of its emissions.
