Abstract:

The change of exhausted gas temperature has a great influence on boiler efficiency. After the 600MW direct aircooled lignitefired subcritical unit of Baiyinhua Jinshan Power Generation Company Limited put into operation, there exist a problem of high exhausted gas temperature. This paper deeply analyzed the main reason of high exhausted gas temperature, and adopted some measures, such as adjusting oxygen volume, optimizing coal pulverizing system and adjusting combustion, etc. Then it conducted a technical transformation of economizer. After the transformation, the exhausted gas temperature reached the design value basically.
