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.
This series boiler is single drum horizontal type shell boiler, the combustion equipment is chain grate, has the advantages of feed mechanically and strong adaptability of different fuels.
DZL series coal fired steam boilers are designed as single-drum boilers with fire tubes and water tubes. They have fast heat conduction, fast steam pressure rise, strong adaptability to biomass fuel, compact structure and high thermal efficiency. This series of steam boilers adopt the latest science and technology in the industry such as arched tube plate and threaded flue smoke pipes, which effectively improves the overall efficiency of the boiler and prevents the occurrence of faults such as grate coking and tube plate leakage.
Performance advantage
1, the use of efficient heat transfer components - threaded smoke pipe, with a reasonable flow rate of flue gas, boiler thermal efficiency than the national professional standards of 6-8 percentage points higher.
2. Arched tube plate and threaded smoke pipe make the pot shell change from quasi-rigid body to quasi-elastic body, and cooperate with airfoil flue, completely avoid the defect of cracking of high temperature tube plate of traditional firework tube boiler.
3. Reasonable water circulation loop and unique backwater ejector device (hot water boiler) can improve the water speed of rising pipe and avoid the pipe bursting of water-cooling wall.
4. Adopt the inertial separation of smoke and dust in the furnace, supplemented by efficient multi-pipe dust collector, so that the dust concentration of the boiler can meet the requirements of a class of areas.
5. Reasonable boiler structure can support its own weight without steel frame.
6, the use of energy saving, strong radiation furnace arch, can ensure the stable combustion of fuel.
7. Adopt high standard and high quality auxiliary machines, accessories and automatic control equipment to ensure the safe and stable operation of the boiler and reduce the labor intensity of the stoker.
8. Compact structure, 1-20T /h(0.7-14MW) boiler can be arranged in one layer.
-automatic fuel feeding duel to chain grate design;
-high efficiency due to big heating surface and grate area;
-low emission,friendly to environment;
-wide fuel adaptability, applicable for wood pellet, coal, palm nuts, etc;
-intelligent boiler controller with PLC and touch screen, easy for operation and parameters setting;
-good looking & long life span;
