Application of improved HT-NR3 swirl burner in supercritical and ultra supercritical unit boilers
Taking two(ultra)supercritical boilers as the examples
operating characteristics of the improved HT-NR3 swirl burner and its combustion adjustment test results were presented.The effects of air distribution parameters on boiler operating economy and pollutant emissions were discussed.Moreover
against the widespread problems of swirl burner
such as high CO concentrations
high temperature corrosion of water wall
combustor nozzle slagging
steam temperature and oxygen deviations
corresponding regulations were proposed to improve the boiler efficiency and reduce pollutant emissions
like on the internal secondary air flow of main burner
the opening degree of external swirl damper in the main burner
the external swirl damper of SOFA burner
internal direct air flow of SOFA burner and two side dampers of wind box.
