DZL series chain grate biomass steam boiler, is a kind of horizontal three-pass water tube and fire tube shell boiler, the left and right side water cooling wall of furnace is radiation heating area, both side of flue and thread fire tube of inner boiler drum is convection heating area. Front and back furnace wall and both side of water cooling wall made up of refractory bricks. Use light chain grate add fuels mechanically, and equip with blower, draft fan for mechanical ventilation, also equip with scraper slag extractor for discharging the ash automatically.
Performance Features:
1. Excellent Chain Grate
1.1 The small scale chain grate boiler could resist the temperature as high as 1200℃, long working life.
1.2 The chain grate has a low coal leakage because of the small gap.
1.3 High automatic degree, decrease labor cost.
1.4 Convenient for maintenance, it could be done without boiler shut down.
1.5 For solid fuels with high humility, increase the length of preheating section of chain grate, to dry the fuels before burning, increase combustion efficiency.
2. High Thermal Efficiency
2.1 The spirally corrugated tube strengthen the heat transfer, improve thermal efficiency. The flue gas has the foundation of disturbance, avoid ash depositing in tube.
2.2 The furnace wall was poured entirely by the heat-resistance concrete and high-temperature-resistance refractory brick, and the boiler shell use aluminium silicate board for heat preservation, low heat loss.
2.3 Equip with economizer, make full use of the heat of flue gas, decrease the exhaust smoke temperature, increase thermal efficiency.
3. Anti Coking
3.1 For the easy coking biomass fuels, increase the size of furnace, large space to achieve sufficient combustion.
3.2 Adopts unique double secondary air design, improves the ignition condition of biomass fuel, sufficient air supply to make sure the high combustion efficiency.
4. 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.
5. Avoid Tube Plate Cracking
5.1 The boiler adopts arched tube plate and spirally corrugated tube, change the quasi-steel body into quasi-elastic body structure, reduce stress, solves the problems of tube plate cracking.
5.2 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.
6. 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 increases the radiant heating surface, to ensure the sufficient output.
7. Environmental Protection
7.1 The biomass fuel do not content sulfur, do not pollute the environment, and the cost on biomass fuel is low.
7.2 The splayed wall and smoke outlet have the function of dust removal, decrease the concentration of smoke emission.
