Among the industrial boilers, circulating fluidized bed (CFB) boiler is a special kind of boiler with low pollution and clean combustion technology. The 20TPH coal fired CFB boiler can be used for pharmaceutical application. Pharmaceutical boiler types can vary depending on fuel source, unit location, emissions, boiler controls, and heating requirements. ZBG can help you maximize the efficiency of your coal fired CFB boiler by repairing or upgrading super heaters, water well panels, power and process piping, drums, and more.
The 20 ton coal fired CFB boiler for Pharmaceutical Industry is a natural circulation water tube boiler with double cross drums. Fuel is sent to the furnace from stoker and it is mixed with air from equal pressure air chamber, the flow gas produced from it burned goes upside into horizontal cyclone separator. The separator is composed of three pieces of membrane walls to guarantee separator work reliable. Flying ash in the flow gas is separated by mass force, and it is sent into the furnace to re-burn by air along feedback path, which improve the burning efficiency,. Flow gas from cyclone separator, after re-separated by U-flue to get rid of ash, flushes convection bank breadth wise. Cast iron economizer and air heater are both one stage, and flow gas gets into dust catcher from air heater and is finally discharged to chimney by induced draft fan.
