摘要
兴建垃圾电站是解决城市环保及实现资源再生的主要方法。由于垃圾电站的特殊性 ,《小型火力发电厂设计规范》不能满足垃圾电站汽机及主要辅机的选型。根据设计实例 ,垃圾电站应选用进汽温度 42 5℃ ,压力在 4.5～ 5MPa之间的汽轮发电机组 ;对于主要辅机 ,除氧器、给水箱、给水泵、汽机旁路、凝汽器、凝汽器抽气器均与小火电机组不同。建议尽早编制有关的设计规范并及早研制垃圾电站的汽轮机组和低流量高扬程的给水泵系列产品 ,以促进我国垃圾电站的设计和发展。
Construction of the refuse power stations is a major method to solve the urban environment protection and realize the regeneration of resources.Due to the specificity of the refuse power station 《Design code of small thermal power plants》can not meet the model selection for turbine and main auxiliaries of the refuse power stations.According to the practical design the refuse power station should adopt the turbine-generator unit with a steam input temperature of 425℃and pressure between 4.5～5 MPa;while for major auxiliaries,deaerator,feedwater tank,feedwater pump,turbine bypass,condenser,condenser air extractor are all different from the small thermal power units.It is recommended to work out concerned design codes and develop the turbine unit and serial products of feedwater pump with low flow and high head for refuse power stations in order to promote the design and development of the refuse power stations in China.
