660MW secondary reheat ∏ type boiler start up commissioning technology study

Abstract

Abstract:

Secondary reheat technology was widely applied due to high economic efficiency. This is not any application of secondary reheat unit in our country yet. Base one the first 660MWclass ultrasupercritical secondary reheat boiler, the unit boiler features were introduced. Key technologies of secondary reheat boiler were discussed from cold state ventilation test, low load stable combustion, preliminary burning adjustment and other aspects. Solutions for the problems of combustor, fan and control logic were provided. After commissioning and improvement, unit operation is stable and reliable. All parameters meet the generation requirements.

Key words:
