In the past 10 years

the economizer of 330 MW CFB boiler in FY power plant has been running for many times

such as tube burst

blown-out and stoppage. The abrasion of medium and high temperature section is particularly serious. At the same time

due to tube burst

25 tubes have been blocked up

resulting in high exhaust gas temperature of the current boiler

which has seriously affected the safety and economy of the boiler. In order to solve the problem of high exhaust gas temperature caused by severe wear and tear

technicians

through investigation and analysis

put forward the transformation scheme of replacing middle and high temperature section and retaining low temperature section

which has achieved good results in implementation

not only good operation of the equipment

but also brought considerable economic benefits.
