Product Description

DZH type active grate biomass steam boiler has a wide range of fuel sources. It is a renewable green energy source. It contains almost no sulfur and less ash. Its growth process can absorb all the CO2 generated by the combustion process and achieve zero CO2 emission. Biomass energy will gradually replace coal and become one of the main energy sources. Biomass fuels include straw, wood shoots, bamboo wood processing waste, grain shell skin, fruit shells, sugar residue, oil residue, and so on.Compared with coal-fired boilers, biomass fuels are less expensive and significantly reduce operating costs.

Boiler Specification

Boiler Advantage

 1. The boiler is a horizontal fast-installed steam boiler with natural circulation of working fluid. The steam boiler heat exchange system is composed of a boiler drum, left and right headers, and water walls. The main heating surface has a water wall in the furnace, and part of the drum and the drum have convection. Tube bundle. This series of steam boilers are composed of five parts when they leave the factory: the boiler body, flue duct, dust collector, and piping system. The first four parts have been manufactured in the factory and can be transported to the installation site for assembly, which can be greatly shortened The installation cycle can guarantee the quality of product installation.
    2. High-quality boiler design performance: The main heating surface tube of the steam boiler is made of seamless steel pipe for 20# low and medium pressure boiler, and the drum is made of special steel plate for boiler. The left and right headers are made of seamless steel pipe.
    3. The steam boiler arch is made of refractory concrete. The back arch is low and long, so it burns well. The two wings flue and side wall bricks are made of refractory sintered bricks. The front and back walls of the boiler are made of general refractory bricks.
    4. The boiler grate has reasonable air distribution, large combustion chamber, and strong coal type applicability. It is suitable for all kinds of bituminous coal, anthracite, and mixed coal. It burns fully. Because the high temperature flue gas enters the settling chamber, it enters the two-wing flue from both sides, The front smoke box, so the smoke and dust removal effect is good.
    5.The water cycle is simple, the structure of the pressure parts is reasonable, and it can be operated safely under the condition of ensuring the water quality.
6. The boiler combustion equipment is a quick-installed grate. The combustion equipment is manufactured and installed in the factory and can be directly installed on the foundation after being transported to the construction site. It has a reasonable and compact structure and low steel consumption, which makes the boiler performance, weight and structure Compared with domestic boilers of the same capacity, the size has obvious advantages

2.fuell set 2 ton capacity industrial biomass pellet steam boiler can load in one 40ft flat rack due to over-width
3.fuell set 4 ton capacity industrial steam boiler can load in one 40ft flat rack also due to over-width

FAQ
1. 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%
 
2. 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
 
3. 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.
