szl series biomass-fired steam boiler vertical dual drums chain grate water tube steam and hot water boiler, adopts quick fitting and assembly structure. The 4-6t/h boiler is of quick fitting tube structure, exit shop after completely assembled, the boiler of 6-35t/h is composed of 2 main components. The upper assembled component is the boiler proper heat absorbing part, and the lower assembled component is of combustion equipment. The former part of the boiler proper is arranged a membrane wall, the upper part of it is connected to boiler cylinder, and its lower part is connected to collective chest, so as to form a combustion room and absorb the radiated heat from the furnace. Its rear part is arranged with dense convection tubes between upper and lower boiler cylinders. The high temperature smog after combustion shall stand for twice returning flushing transversely to the heat accepting surfaces, and shall be introduced to coal saver singly arranged, and flow into duster and exhausted from chimney in the end.
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.
Automatic production line.
The welding of important parts like the vertical and circular seams of the boiler, the tubes, the inside of boiler and the flange are all adopted automated welding processes such as submerged arc welding or gas shielded welding to ensure the welding quality. All the vertical and circular seams will be done 100% radiographic inspection.
Tube flange weld adopts robot welding.
The chain grate panel, front and rear smoke chamber panel adopts CNC plasma cutting machine to cut orderly and beautifully.
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.
According to different capacity, different numbers of independent air bins are arranged from front to back of the grate.
The user can reasonably adjust the air distribution according to different combustion conditions to ensure that the fuel is fully burnt.
Secondary air is input to disturb fuel gas in the furnace, to ensure the fuel is burnt totally. The independent secondary fan makes it easy to control and adjust the air volume and air pressure.
Feeds evenly feeding and avoid flashback.
