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.
