QXX Series 14MW Circulating Fluidized Bed Boiler

QXX Series 14MW Circulating Fluidized Bed Boiler has the characteristic:combustion efficiency and boiler thermal efficiency is very high. Conducive to ash utilization.improving economic efficiency.

QXX Series 14MW Circulating Fluidized Bed Boiler adopts double drums.Fuel is into the furnance by coal feeder.It burns with air from isobaric bellows.The gas from burnning goes up into horizontal cyclone. Cyclone is composed by three membrane wall so as to keep the cyclone operation stable.The ash from gas is seperated by inertia.It is sent into furnace by loose wind through back forehearth.Then it circulating burns. It improvs the burnning efficiency.The seperated gas go out from cyclone.It from up to down through U flue bend ,further separate the particals from flue gas,scour convection tube bundle.Then goes into steel economizer.The economizer is two layout.Flue gas scour the economizer into air preheater,then into the chimmey by ID fan through dust collector. Boiler ventilation mode isthe balanced ventilation of blower and fan.

Layout and select measuring points must be met with TSG G0002-2010(Appendix B:Boiler Instrument Configuration Requirements).Boiler must be install the interlocking devices.When all induced draft fan power outage,it can automatically cut off the air and fuel supply.When all forced draft fan power outage,it can automatically cut off the fuel supply.
