Structure
Combustion process:
The fuel enters the furnace and burns on the grate. The flue gas from the production enters the convection tube bundle on both wings along the bottom of the boiler barrel through the smoke outlet on the middle partition wall, enters the threaded smoke pipe through the front smoke box, passes through the dust collector, and is pumped and discharged into the atmosphere through the chimney by the induced draft fan.
Technical characteristics
11. High Thermal Efficiency
1.1 The spirally corrugated tube strengthen the heat transfer,
improve thermal efficiency. The flue gas has the foundation of
disturbance, avoid ash depositing in tube.
1.2 The furnace wall was poured entirely by the heat-resistance
concrete and high-temperature-resistance refractory brick, and the
boiler shell uses aluminium silicate board for heat preservation,
low heat loss.
1.3 Equip with economizer, make full use of the heat of flue gas,
decrease the exhaust smoke temperature, increase thermal
efficiency.
2. Anti-coking
2.1 For the easy coking biomass fuels, increase the size of
furnace, large space to achieve sufficient combustion.
2.2 Adopt unique double secondary air design, improve the ignition
condition of biomass fuels, sufficient air supply to make sure the
high combustion efficiency.
3. Avoid Bulging
The riser tube bundle under the 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.
4. Avoid Tube Plate Cracking
4.1 The boiler adopt arched tube plate and spirally corrugated
tube, change the quasi-steel body into quasi-elastic body
structure, reduce stress.
4.2 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.
5. Sufficient Output
Adopt 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
increase the radiant heating surface, to ensure the sufficient
output.
6. Environmental Protection
6.1 The biomass fuels do not content sulfur, do not pollute the
environment, and the cost of biomass fuels are low.
6.2 The splayed wall and smoke outlet have the function of dust
removal, decrease the concentration of smoke emission.

1. Q: What is steam boiler used for?
A: Industrial steam boiler are designed for low-pressure or high-pressure applications. Low-pressure boilers are limited to 15 psig design, and are typically used for heating applications. High-pressure boilers are typically used for process loads and can have an operating pressure of 16 to more tan 1000 sig. Most steam boiler systems require saturated steam, which means the water and the steam in the vessel are at the same temperature.
2. Q: What are the available fuel for the steam boiler?
A: Natural gas, LPG, Light Oil, Diesel, Heavy oil, oil/gas dual fuels, coal, biomass pellet, rice husk, bagasse, etc.
3. Q: What capacity are provided for steam boiler?
A: 0.5t/h, 0.7t/h, 1t/h, 2t/h, 3t/h, 4t/h, 6t/h, 8t/h, 10t/h, 12t/h,15t/h, 20t/h.
For other capacity, please confirm with us firstly.
4. Q: What design pressure are provided for steam boiler?
A: 0.7Mpa(7Bar), 1.0Mpa(10Bar), 1.25Mpa(12.5Bar), 1.6Mpa(16Bar).
Operating pressure can be controlled in the range of design pressure.
5. Q: What’s the differences between fire tube boiler and water tube boiler.
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.
Horizontal type:
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.
