The Retrofit of Pulverized Coal Burner to GB-65/39-M Boiler&Its Optimization Combustion Adjustment

Cheng Qing-gang

Abstract

After saving energy technical retrofit of BG-65/39-M boiler,the pulverized coal burner was changed to the type of STF-Ⅲ,namely two-way stable combustion pulverized coal burner.That resulted in combustion sta bi -lization when lean coal was combusted and heat efficiency was enhanced,also the ratio of carbon in flying ash was re-duced.The boiler may be performed stably at it60%specified load with out oil aid.
