1.corner tube chain grate:

The ZG biomass fired steam boiler adopts corner tube pattern,self-supporting structure.This kind of structure is simple and reliable.

All welded membrane water wall structure is adopted around the furnace and the descending gas pass, which contributes to the good sealing,less heat loss of them and makes them clean.

Both the air preheater and the coal economizer adopt box structures,which ensures the easy transportation and installation of the boiler,and strengthens the seal performance of tail fuel gas duct.

The flag pattern heat surface is arranged before the high-temperature superheater so that the high temperature ability of superheater can be ensured,thus the superheater can operate stably in the serious fuel gas environment produced by the burning of biomass.

The ZG biomass fired steam boiler uses the crossgirder grate,it has the features of less operation resistance, better cooling effect,lower breakdown rate and less fuel leak. And the combustion system is manufactured by the first-rated domestic manufacturer.

The fuel is sprayed into the furnace,which ensures the layer combustion and suspension combustion of fuel,thus the combustion efficiency is enhanced.

The ZG biomass fired steam boiler adopts the light grate wall structure,the boiler weight is light.

The fuel for this boiler is only straw or other kinds of biomass material so the ash and slag left can be used as fertilizer directly.Thus,it is a high efficient, energy-saving and environment-friendly product.

2.circulating fluidized bed:

The ZG biomass fired steam boiler adopts the structure of single drum transverse type,"π" type layout.

Suspended membrane water wall structure furnace,and the inlet of separator is membrane water-cooled gas pass.

The bell jar type blast cap is easy to replace and has low resistance.

The separator and center cylinder has low resistance and high separating efficiency.

The feeding device with patent technology is adopted and the independent roots blower is equipped to provide wind,thus the power consumption is lowered.

Low bed pressure operation mode is adopted.

The use of low pressure fans reduces the power consumption.

Optimization of the secondary air layout and the vents flow rate reduces the secondary air pressure head.

The air preheater adopts the multi-tube box arrangement and the low-temperature section uses the corrosion-resistant steel,which avoids the wholesale replacement caused by low-temperature corrosion.
