摘　　要：针对新建填埋气发电厂在投运初期存在填埋气产量不足,发电机组容量不能有效利用问题,提出掺烧天然气助燃方案。采用此方案后,填埋气发电机组效率的提高与多利用低甲烷含量填埋气将取得一定收益。通过对荣昌填埋气发电厂数据分析计算,若荣昌电厂采用掺烧方案,估算其2016年11月、12月以及2017年1-4月将多取得6.784万元、6.273万元与24.627万元收益,掺烧方案具有良好的经济性。Resource utilization of landfill gas is mainly used for power generation in China. However, the shortage of landfill gas production and low capacity usage of generator sets always impacted the income of new landfill gas power plants, a co-firing project was put forward to solve those problems in this paper. After adopting the project, the efficiency improvement of landfill gas generator sets and making the use o^more low methane content of landfill gas can gain a certain benefit. Through the data analysis of Rongchang landfill gas power plant, the revenue grew 67.84 thousand R_MB in Nov 2016, 62.73 thousand RMB in Dec 2016, and 246.27 thousand RMB from Jan to Apr 2017 compared with the same period, when the power plant put the project into operation. To summarize, the co-firing project have a favorable economic performance.
