10、流线型铸铁式节煤器完成单位:常州锅炉厂、南京工学院该课题是在对现有3种节煤器的技术性能和经济指数进行比较,对某些节煤器的堵灰现象进行分析后而研制出的新一代流线型铸铁式节煤器。使用该节煤器可减轻积灰,避免堵灰。用于2 T/H以下锅炉,热效率可提高8～9%,用于4 T/H以上锅炉,热效率可 10. Streamlined cast iron type economizer Completed units: Changzhou Boiler Works, Nanjing Institute of Technology This topic is to compare the technical performance and economic index of the existing three types of economizers and to perform certain ash blocking phenomena for economizers. A new generation of streamlined cast iron economizer was developed after analysis. The use of the economizer can reduce dust accumulation and avoid clogging. For boilers up to 2 T/H, thermal efficiency can be increased by 8-9%, for boilers above 4 T/H, thermal efficiency can be
