2 Ton/H 2000 Kg/Hr Biomass Steam Boiler For Corrugated Box Production Line
DZH horizontal biomass steam boiler
Specification model: 0.5 -- 4 tons
Thermal efficiency: 85%
Applicable fuel: biomass pellet, wood block, straw
Application: heating, central heating, hot water, aquaculture, bathing, etc
DZH type biomass pellet fired steam boiler is a horizontal three-return water-fire tube type boiler. A row of water-cooled wall tubes are arranged on the left and right sides of the furnace, and two sets of tube bundles are arranged in the drum to form two return paths. The boiler has sufficient heating surface and is equipped with a tail heating surface economizer. It is equipped with drums and induced draft fans for mechanical ventilation. Layered combustion.
This biomass steam boiler has high automation level, automatic adjustment of boiler feed water, high and low water level alarm, low water level interlock protection, and interlocking protection of lead and blower. Auxiliary auxiliary equipment is complete.
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.

Automatic control and fault protection features
Boiler steam pressure automatic regulation system: boiler steam pressure automatic regulation system control system into the state of work, to meet the necessary conditions of combustion: boiler steam pressure is higher than or equal to the set pressure limit, the control system output stop signal.Until the induced draft fan is stopped.
Water supply automatic control: when the system is working or normal, start the water pump, the water pump will work, the water level differential pressure transmitter will detect the water level signal and keep the water level of the drum stable.Ensure the quality of steam.The water level gauge shows the boiler water level.
Manual control: you can also manually control the water pump by touching the button manually on the control panel.
Application for biomass steam boiler
Wood fired steam boiler is suitable for painting room, drying box, drying tower painting line and other purposes.It is especially suitable for central heating in urban residential areas, industrial production, enterprises and institutions, schools, hotels, bath centers and other places where heating, hot water and steam are needed.
