Abstract:

To improve the safety and economic efficiency of boiler soot blowing system, steam resource shall be properly selected. After compared three steam resource plans, mixed resource from high pressure cylinder exhaust and low temperature reheater inlet was selected. After reconstruction, boiler heat consumption rate and generation coal consumption decreased. Working condition of soot blowing control valve was improved. Unit safety was enhanced.
