DZH biomass horizontal steam boiler, is a horizontal three - return water - fire tube hybrid boiler, in the boiler barrel arranged with a bunch of threaded smoke pipe.The left and right sides of the furnace chamber are equipped with water cooling walls of light pipes.It adopts light movable grate, manual feeding, equipped with blower and induced draft fan for mechanical ventilation.The front and rear arches of the furnace adopt new energy saving technology.After the fuel falls on the grate, enters the furnace and burns, the flame, through the rear arch refraction, turns upward through the burning Chambers on both sides of the body, turns back to the front smoke box, and then returns to the tube bundle in the pot through the front smoke box, enters the economizer through the rear smoke box, and then is pumped by the induced draft fan to the air through the flue to the chimney.
Boiler feature
1,Horizontal,3 pass and large furnace
Ensure the sufficient combustion.
The large diameter boiler increase the heating surface to ensure the high thermal efficiency.
2,The spirally corrugated tube
Strength the heat transfer and improve the thermal efficiency .The smoke in the tube has the distribution effect,the dust not easy to deposit ,the tube can cleat by itself.
3,High temperature resistance refractory brick
The furnace wall is poured by the heat resistance concrete and high temperature resistance refractory brick,decrease heat loss,increase the boiler thermal efficiency.
4,The economizer
Made of ND corrosion resistance steel,make full use of gas heat .reduce the exhaust temperature improve thermal efficiency.
Manual operation type boiler belong to DZH series boiler,its main featuers as fellow: horizontal type,feed fuel by hand with less trouble when oprating wood chips boilers.
