湖州市餐厨垃圾产沼气发电能值分析
|
Abstract:
为实现餐厨垃圾资源化利用，依托湖州市餐厨垃圾产气试点项目，采用能值分析方法分析了湖州市餐厨垃圾产沼气发电和火力发电的环境影响。结果表明：基于能值分析方法，列出两种发电模式的能值输入输出表，并选取了五个能值指标进行计算分析，其中，餐厨垃圾生产沼气进行发电的能值转换率约占到传统火力发电的十分之一，环境负载率(ELR)低于火力发电的81.52%，可再生指数(PR)高于火力发电的75%，能值产出率(EYR)和环境可持续性指数(ESI)也都高于火力发电。
In order to realize the resource utilization of kitchen waste, based on the pilot project of kitchen waste gas production in Huzhou City, the energy analysis method was used to analyze the envi-ronmental impact of biogas and thermal power generation from kitchen waste in Huzhou city. The results showed that: Based on the energy analysis method, the energy input and output tables of the two power generation modes are listed, and five energy indexes are selected for calculation and analysis. Among them, the energy conversion rate of biogas produced by kitchen waste for power generation accounts for about one-tenth of that of traditional thermal power generation, and the environmental load rate (ELR) is lower than 81.52% of that of thermal power generation. The renewable index (PR) is higher than 75% of thermal power generation, and the energy rate (EYR) and environmental sustainability index (ESI) are also higher than thermal power generation.
