秸秆发电系统能值分析
Energy Evaluation of Straw-based Power Generation System
摘要
Abstract
Energy analysis was applied to evaluate three typical straw-based power generation systems: 1 MW gasification and power generation system, 5. 5 MW gasification and power generation system, and 25 MW combustion and power generation system. Based on the concepts of energy costs and energy benefits, two indicators were employed: environmental yield ratio (EYR) and net energy. The results show that the 5. 5 MW system is the most efficient one in recovering energy from straw ( the highest EYR) and is capable of saving the greatest quantity of energy per MJ of straw used ( the highest net energy) ; the 1 MW system is the best one in terms of energy costs, but the worst in terms of energy benefits. Compared with the 1 MW system, the 25 MW system has a lower EYR but higher net energy.关键词
