Product Description
DZL series coal/biomass fired steam boiler realizes almost zero pollution with the use of special dust collector solution (bag dust collector, double towers desulfurization, etc.). This series boiler is single drum horizontal type shell boiler, the combustion equipment is chain grate (small scale flaker is available), has the advantages of feed mechanically and strong adaptability of different fuels. The fuel could be II class bituminous coal, the diameter should be 6-25mm, and ash content should be less than 32.4%. Otherwise, DZL series boiler could also burn biomass fuel, including wood, straw, bagasse, rice husk, coconut shell, cotton seeds, peanut shell, etc

Biomass Fired Boiler Burning process
The fuel falls from the coal hopper to the front of the grate. With the operation of the grate, the coal undergoes preheating, dry distillation, ignition, and embers. The slag falls into the slag hopper and is discharged from the furnace at any time by the slag remover. The flue gas is in the front and back arches. The throat between the throat can form a vortex to fully mix with the air, heat the front arch, improve the fire conditions, enter the two-wing convection tube bundle through the exit smoke window on the upper part of the arch, enter the threaded smoke pipe through the front smoke box, and pass through the economizer and dust collector. The induced draft fan is led to the chimney and discharged.

Steam Boilery Heating System
biomass boiler fuel has wide applicability, which can be applied to coal, biomass particles, sawdust, palm shell, straw and other fuels; At the same time, relevant structures shall be reasonably designed according to different fuel characteristics to ensure efficient, energy-saving and stable operation of the boiler.
DZL series coal boilers are widely used in food factory, drinking factory, juice factory, sugar refinery, tire factory, soap factory, cement production, concrete production, paper-making, brick-making, carton plant, chemical fertilizer plant, feed mill, knit mill, tissue mill, textile mill, palm oil factory, gloves factory, alcohol plant, chicken processing plant, instant noodle plant, medical and chemical industries, etc.
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.
