Product Desciption
Product Characteristics:
DZL series package boilers are horizontal three-pass water & fire tube boilers with a chain grate stoker structure. Threaded pyrotechnic tubes are arranged in the drum to form a convection heating surface, while the drum and the water walls on both sides form a radiation heating surface in the furnace. Each package system is fully installed and wired before being transported to site and is electrically controlled to provide functions such as stepless speed regulation for the stoker, threshold parameter alert and interlock protection.
Technical advantages:
1.Energy saving and environmental protection: uses the latest gas combustion technology, sets up advanced gasification rotary combustion chamber, the rotational flow secondary air distribution, makes the fuel burning more fully.
it uses the high efficiency heat transfer original threaded pipe, with reasonable flue gas flow rate, so that the boiler thermal efficiency is more improved. Thermal efficiency can reach above 85%.
Boiler adopts the national promotion of green renewable biomass wooden pellet fuel, CO2 achieves zero emissions, dust emission concentration fish 50mg / m3, flue gas blackness is less than Salinger I the level, the indicators reach the first class national regions environmental standards.
2.Low operating cost: because the boiler itself using lignocellulosic biomass fuel particles belongs to the country to support the promotion of new environmentally friendly fuel ,which is a renewable resource. With high calorific value,low cost,characteristics of a wide range of sources. The operation cost is only one fourth of the electric boiler, burning oil (gas) boiler under half.
3. High degree of automation: digital integrated controller, it can automatically control the combustion conditions according to the user sets, the operation is simple and convenient, automatic ignition, automatic feeding, automatic cleaning, and same convenient as the fuel, gas boiler operation.
4.Safety: it uses the high standard, high quality auxiliary , appendix and automatic control equipment ensure the safety of boiler and the steady operation.
CNC manufacturing technology
The key processing technologies such as steel plate blanking, circling, drum and tube plate drilling adopt advanced CNC machining to reduce the assembly stress and prolong the service life of the boiler.
Steel tube cutting, thread tube pressing and convection tube processing all adopt advanced CNC technology.
Arched tube sheets and threaded fire tube was first adopted in China to increase heat transfer and completely solve the problem of cracking of the back tube sheet.
Chain grate plate and back smoke chamber plate is cut by CNC plasma cutting machine, which looks neat and beautiful.
Advanced welding process
The vertical and circumferential seam welding of the boiler adopts advanced automatic submerged arc welding technology to ensure the welding quality. All vertical and circumferential welds will go through 100% ray detection.
The welding of smoke tube and the tube plate adopts pre-expansion to eliminate the gap between the tube and tube plate, then be welded by automatic argon arc welding, which effectively eliminate stress and prolong boiler life.
The flange of the socket is welded by robots.
The chain grate is manufactured by our factory, and it is tested for 72 hours before leaving the factory to ensure that the tightness is moderate and won't deviate.
Precision parts processing
Advanced manufacturing technology, using assembly line automatic spinning manufacturing.
Enhance heat transfer and raise boiler thermal efficiency.
Threaded smoke tubes are highly efficient heat transfer elements which is from many years research of our company. After continuous optimization, the heat transfer coefficient is 1.8 times higher than normal smoke tubes.
Unique structural design
Disturbed flue gas to ensure complete combustion of volatiles.
The air volume accounts for about 30% of the total, and the wind speed is about 50m³.
The independent secondary fan makes it easy to control and adjust the wind volume and pressure.
The high-temperature smoke generated by the combustion first enters the horoscope flue on both sides of the boiler proepr from the tail (in this case, the boiler is water tube type), and the flue gas flows outside the tube.
The flue gas cooled by the horoscope flue enters the threaded tube (in this case the boiler is fire tube type) arranged in the drum from the front smoke chamber.
The flue gas will be exhausted from the back smoke chamber, this design fundamentally solves the problem of cracking of the tube sheet of a simple fire tube boiler.
Abundant auxiliary configuration
Feeder: Feeding fuel equally to avoid flashback.
Gearbox: Designing reasonable rotating speed according to the combustion speed to make sure the fuel burning completely.
Cover plates: Cold-rolled pressed plates, strong and elegant.
Inspection door: reasonable manhole and hand hole layout, easy for maintenance. Inspection doors in furnaces for easy access and maintenance.
Scope of application:
Horizontal automatic biomass fired steam boiler main purpose is to provide high quality steam and motive power for industrial production, such as textile, papermaking, rubber, food, hospital and other industries.
