Based on situation of debugging in start-up of supercritical boiler with W-shaped flame in Xingyang Power Plant

the main technical points in start-up of said boiler

such as control of temperature and thermal deviation

control of boiler water circulating pump

manipulation in transfering process to once-through operation

as well as prevention of off-set burning etc.

have been summarized and optimized.After adopting corresponding measures

abnormalities in start-up and operation

i.e.overtemperature

unstable combustion

outfire

water-flooding

water shortage

and fault of boiler water pump etc.

haven't occurred

the operation parameters and various indices all reach excellent level.
