ZG Series 75 t/h Mediate Pressure Biomass Boiler is natural circulation, "N"layout,it adopts corner boiler self-load bearing structure.
ZG Series75 t/h Mediate Pressure Biomass Boiler introduction
ZG Series75 t/h Mediate Pressure Biomass Boiler adopts cleaning combustion technology.It's fuel is straw.Staw energy is released though reasonable burning.It transfers the thermal to water.Water turns into steam.It is for power station or production crafts.The boiler is fit for kinds of staw fuel.The combustion efficiency is high.It can resolve the effect of high chlorine, sulfur which is contented in the staw fuel.It can reduce the corrosion and wear of equipment.It also can reduce the environment pollution.It has the feature of high burning efficiency and low pollution.The boiler doesnot add to other bed material.The ash and dregs which is exhausted from the boiler can be used for farmyard fertilizer.So it is high-efficiency,energy-save,environmental-protect production.
ZG Series75 t/h Mediate Pressure Biomass Boiler water circulation is natural circulation ,N layout. It adopts corner boiler self-load bearing structure,the tail adopts frame support structure. The full welded membrane water-cooler wall around the furnance and the down flue.the down flue layout high and low superheater, double degree convection heating surface.Spray detemperature device layout in the middle of double degree convection heating surface,section economizer and air preheater layout in the tail upper flue.
ZG Series75 t/h Mediate Pressure Biomass Boiler is designed as the interior decoration,operation floor elevation is 7m,The boiler architecture is metal structure.it is for 7 degree seismic intensity
