DZH series coal/biomass fired steam boiler realizes almost zero pollution with the use of special dust collector solution. This series boiler is single drum horizontal type shell boiler, the combustion equipment is moving grate. The fuel could be II class bituminous coal and biomass fuel, the diameter of coal should be 6-25mm, and ash content should be less than 32.4%, and for the biomass fuel, carbon content should less than 50%, sulphur content less than 0.08%, and ash content less than 3%.

Working principle
The horizontal hand-fired biomass steam boiler is composed of a shell, a head, a furnace liner, a furnace roof, a U-shaped ring, a cupola, etc. The combustion chamber is arranged in the furnace liner, and the furnace is divided into two upper and lower chambers with a refractory concrete furnace arch. In the combustion chamber, the flue gas generated from the lower combustion enters the secondary combustion chamber through the throat of the refractory concrete furnace arch and is mixed with the secondary air input from the upper furnace door to be fully combusted. The high temperature flue gas generated is radiated and heat exchanged by the heating surface of the furnace. After that, convection heat exchange is performed again through the annular smoke box, and finally discharged into the atmosphere through the chimney.
Applicable fuel This product uses a chain grate. The applicable fuel is shaped pellet fuel. A small amount of wood slats and blocks can be added, or it can be mixed with coal.
Technical Specification

1. The steam boiler is the horizontal quick-loading boiler with natural circulation of working medium.
The boiler heat exchange system is composed of a boiler barrel, a set box and a water cooling wall. The main heating surface is composed of a furnace water cooling wall, part of the boiler barrel and a convection tube bundle inside the boiler barrel.
2. Advanced design performance:
The main heating surface tube of the boiler is made of seamless steel tube of no. 20 low and medium pressure boiler, and the boiler barrel is made of special steel plate for the boiler.The left and right containers are made of seamless steel tubes.
3. The boiler arch is made of fire-resistant concrete.The rear arch is low and long, so it burns well. The wings of the flue and the side wall tiles are made of refractory sintered bricks.Boiler front wall and back wall adopt universal firebrick.
4. Reasonable exhaust ventilation, large combustion chamber and strong applicability of coal.Suitable for all kinds of bituminous coal or anthracite, mixed coal.Well burned.Because the high-temperature flue gas first enters the settlement chamber, and then from both sides enters the two wings of the flue and the front smoke box, so the effect of smoke removal and dust removal is good.
5. Simple water circulation, reasonable structure of pressurized parts, and safe operation under the condition of ensuring water quality.

The fuel can be biomass pellet, wood chips, waste wood, sawdust, corn stalk, rick husk, biomass pelelt
Application for biomass steam boiler 
Wood fired steam boiler has high heating temperature, low working pressure, energy saving, and can be widely used in various industrial heating processes. Coal fired 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.

1. What are the differences between vertical type boiler and horizontal type boiler with the same capacity?

1. Structure of vertical boiler is compact, occupy a limited area,

2. Convenient on installation and removal.

3. Low cost and investment on capital construction. Steam exhausted fast and sufficient.

1. The combustion space of horizontal is big, fuel can be burned completed.

2. The thermal efficiency is higher than the vertical boiler,

3. Horizontal type: less thermal loss, stronger output, and higher steam quality.

2. What are the limitation (size, humidity, chemical element concentrations) of coal fuel/solid fuel/wood fuel?

Size requirement of coal:6-25mm

Size requirement of blending coal: <50mm (the coal less than 6mm should less than 30%)

Diameter of biomass particle: 6~10mm, length: 25~50mm, water content < 15%, ash content < 2%, sulphur content<0.07%, chlorinity <0.07%, nitrogen content < 0.5%

3. What is the size of furnace door and blower hopper?

Size of furnace door:

Standard elliptical furnace door:300*800*1500

Blower hopper size:

2 tons conical hopper: 1400*800*1500

4 tons conical hopper: 2200*1400*1500

4. What is the combustion mode of coal/biomass fired boiler?

The combustion mode of coal/biomass fired boiler is layer combustion. Place the flue on the fixed or moved grate, to form an evenly fuel bed with a certain thickness, air comes from the bottom of grate, and combustion occurred on the fuel bed.
