Lignite fired Boiler structural features
Lignite fired boiler is of single steam drum, suspension combustion mainly to stoker firing as a supplement, natural circulation and water cooled vibration stoker. Boiler proper, except economizer and tubular air preheater, is complete suspension and membrane wall construction. Meanwhile, validity of various biofuel is also taken into consideration.
Lignite fired boiler is of outdoor arrangement and composed of the following five parts: furnace, primary, secondary and third gas pass, and HRA. Primary air plenum, stoker, furnace combustion zone, rising zone and back panel superheater are arranged in furnace from bottom to top in sequence. High temperature superheater is arranged in primary gas pass, intermediate temperature superheater and primary low temperature superheater are arranged along the direction of flue gas flowing in secondary gas pass. Supporting structure is adopted for the third gas pass and HRA, and secondary low temperature superheater and economizer are arranged along the direction of flue gas flowing in the third gas pass, and air preheater is arranged in HRA. Pressure rating of products includes following two types: meduim pressure (3.82MPa.g) and high pressure(9.8MPa.g). Fuel：crops branch and shell, calorific value proportion could reach 100%.
As a kind of coal fired boiler , Lignite fired Boiler can also be used as bituminous coal fired boiler and anthracite fired boiler ,coke coal fired boiler and other coal fired boiler .
The oil steam boilers from ZG in an output range from 1t/h to 20 t/h are available for a wide range of applications.Based on oil types ,it can be Gasoline fired boiler,Kerosene fired boiler,Waste oil fired boiler,Diesel oil fired boiler,Heavy oil fired boiler,Light oil fired boiler.ZG WNS automatic light oil fired steam boiler is the horizontal, 3-pass, fire-tube boiler, mainly consisted of shell, undee furnace, diversion smoke chamber, fire
