填埋场沼气发电及余热利用的设计与分析

Design and Analysis of Landfill Gas Power Generation and Waste Heat Utilization

根据垃圾填埋场的特点,建立了沼气产气模型,预测了沼气产量与收集量,并进行了相应沼气发电机组的设计。再根据沼气机组的余热特点,提出了余热回收系统中供水增压、热水循环发电、烟气、缸套水和用户热水等系统的发电方案。

According to the characteristics of landfills,the biogas production model was established,the biogas production and collection quantity were predicted,and the corresponding biogas generator set was designed.Finally,based on the characteristics of waste heat of biogas unit,the power generation schemes of water supply pressurization,hot water circulation power generation,flue gas,jacket water and user hot water in waste heat recovery system were put forward.
