DZL series package boilers are horizontal three-pass h2o & fire tube boilers with a chain grate stoker composition. Threaded pyrotechnic tubes are arranged in the drum to sort a convection heating floor, whilst the drum and the water walls on the two sides kind a radiation heating surface area in the furnace. Every package deal method is fully set up and wired just before becoming transported to website and is electrically controlled to give functions this kind of as stepless velocity regulation for the stoker, threshold parameter warn and interlock safety.
1.Strength saving and environmental safety: uses the newest fuel combustion engineering, sets up innovative gasification rotary combustion chamber, the rotational circulation secondary air distribution, helps make the gasoline burning much more completely.
it employs the high effectiveness warmth transfer original threaded pipe, with sensible flue fuel circulation charge, so that the boiler thermal efficiency is more enhanced. Thermal performance can get to over 85%.
Boiler adopts the national advertising of green renewable biomass picket pellet gas, CO2 achieves zero emissions, dust emission concentration fish 50mg / m3, flue fuel blackness is considerably less than Salinger I the stage, the indicators achieve the very first class countrywide areas environmental requirements.
2.Low operating value: since the boiler itself making use of lignocellulosic biomass gasoline particles belongs to the region to assistance the promotion of new environmentally helpful gas ,which is a renewable source. With substantial calorific value,reduced value,attributes of a wide variety of sources. The operation price is only one fourth of the electric boiler, burning oil (gasoline) boiler under 50 %.
3. Substantial degree of automation: electronic built-in controller, it can instantly control the combustion conditions in accordance to the consumer sets, the procedure is easy and handy, computerized ignition, computerized feeding, automatic cleansing, and very same convenient as the gasoline, fuel boiler procedure.
4.Security: it utilizes the substantial regular, large quality auxiliary , appendix and automatic control products ensure the basic safety of boiler and the continual procedure.
CNC production engineering
The key processing systems this sort of as steel plate blanking, circling, drum and tube plate drilling adopt innovative CNC machining to minimize the assembly anxiety and prolong the service daily life of the boiler.
Metal tube slicing, thread tube pressing and convection tube processing all adopt advanced CNC engineering.
Arched tube sheets and threaded hearth tube was 1st adopted in China to boost heat transfer and completely fix the issue of cracking of the back tube sheet.
Chain grate plate and again smoke chamber plate is cut by CNC plasma chopping device, which appears neat and lovely.
Sophisticated welding approach
The vertical and circumferential seam welding of the boiler adopts innovative computerized submerged arc welding engineering to make sure the welding good quality. All vertical and circumferential welds will go through a hundred% ray detection.
The welding of smoke tube and the tube plate adopts pre-growth to eradicate the gap between the tube and tube plate, then be welded by automatic argon arc welding, which successfully eliminate pressure and prolong boiler life.
The flange of the socket is welded by robots.
The chain grate is created by our manufacturing unit, and it is analyzed for 72 hrs before leaving the manufacturing facility to make sure that the tightness is moderate and will not deviate.
Precision components processing
Sophisticated manufacturing engineering, making use of assembly line automatic spinning manufacturing.
Increase heat transfer and raise boiler thermal efficiency.
Threaded smoke tubes are hugely productive heat transfer aspects which is from numerous years investigation of our business. Following steady optimization, the warmth transfer coefficient is one.8 occasions greater than typical smoke tubes.
Distinctive structural design and style
Disturbed flue gas to make certain comprehensive combustion of volatiles.
The air quantity accounts for about 30% of the overall, and the wind velocity is about 50m³.
The unbiased secondary enthusiast helps make it straightforward to manage and modify the wind volume and stress.
The substantial-temperature smoke generated by the combustion initial enters the horoscope flue on both sides of the boiler proepr from the tail (in this case, the boiler is water tube variety), and the flue gasoline flows exterior the tube.
The flue gas cooled by the horoscope flue enters the threaded tube (in this circumstance the boiler is fire tube sort) arranged in the drum from the entrance smoke chamber.
The flue fuel will be exhausted from the again smoke chamber, this design and style fundamentally solves the problem of cracking of the tube sheet of a simple fireplace tube boiler.
Ample auxiliary configuration
Feeder: Feeding gas similarly to keep away from flashback.
Gearbox: Planning sensible rotating velocity in accordance to the combustion speed to make sure the gas burning completely.
Include plates: Chilly-rolled pressed plates, robust and classy.
Inspection doorway: affordable manhole and hand gap format, simple for servicing. Inspection doorways in furnaces for easy access and routine maintenance.
Scope of software:
Horizontal automated biomass fired steam boiler principal purpose is to give high high quality steam and motive power for industrial creation, this kind of as textile, papermaking, rubber, foods, clinic and other industries.
