DZH series manual wood fired steam boiler, use movable fire grate, equip with blower, draft fan, economizer, deduster, automatic water treatment, water pump, steam header, control cabinet, valves and meters etc auxiliary machines. Due to the less of auxiliaries of this series boiler, so low fault of machines, reduce maintenance cost, easy operation, save time and materials, is an economical boiler type. Suitable for various types of coal fuels, environmental protection, price position moderate, is the first choice of small and medium enterprises who use steam for processing line.
Boiler Specification

Boiler Advantage

1. High Thermal Efficiency
1.1 Spirally corrugated tube strengthen the heat transfer and improve thermal efficiency. Flue gas has the foundation of disturbance, avoid ash depositing in tube.
1.2 Furnace wall was poured entirely by heat-resistance concrete and high temperature resistance refractory brick, excellent leakproofness and no air leakage. Boiler shell use aluminium silicate board for heat preservation, low heat loss.
1.3 Equip with economizer, make full use of heat of flue gas, decrease the exhaust smoke temperature, increase thermal efficiency.
2. Avoid Bulging
Riser tube bundle under boiler drum, remove the dead water region at the bottom of drum, sludge is not easy for depositing, the high temperature area of drum has better cooling, prevent bulging.
3. Avoid Tube Plate Cracking
3.1 The steam boiler adopts arched tube plate and spirally corrugated tube, change the quasi-steel body into quasi-elastic body structure, reduce stress.
3.2 Arrange two sides gas duct in drum, the smoke gas could enter into the front smoke chamber smoothly, the temperature of tube plate is lower than 600℃, avoid cracking leaded by high temperature.
4. Sufficient Output
Adopts horizontal type three pass structure and large furnace, to ensure the sufficient combustion, and the boiler could absorb the thermal expansion effectively. The large diameter boiler drum increases the radiant heating surface, to ensure the sufficient output.
5. Environmental protection
5.1 The splayed wall and smoke outlet have the function of dust removal, decrease the concentration of smoke emission.
5.2 The moving grate boiler adopts several environmental protect measures ( bag dust collector, double towers desulfurization, etc.) to meet national emission requirements.

FAQ
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
