燃气分布式能源站余热深度利用技术方案研究

Technical schemes for waste heat deep utilization in gas distributed energy stations

为提高燃气分布式能源系统的余热利用率,结合某分布式能源项目的设计案例,从烟气余热深度利用设备的选型、运行模式、投资及运行经济性等角度进行分析,提出了余热深度利用系统的配置方案。分析了在不同负荷工况下系统的工艺流程及运行模式,对技术方案进行了详细介绍,并与常规技术方案进行了经济性对比。在项目有充足且较为稳定的热负荷需求时,选用合理的余热深度利用方案,具有良好的经济性。

To increase the utilization rate of gas distributed energy stations,taking the design of a distributed energy project as an example,analysis was made from equipment selection,operation mode,investment and operation economy,and a waste heat deep utilization scheme was proposed.The technical scheme was introduced from the technological process and operation modes under different load conditions in detail,and its economy was compared with conventional technical schemes.If there is sufficient and stable heating demand,distributed energy project can be economic within a reasonable waste heat deep utilization scheme.
