SZL Series Double Drum Biomass Steam Boiler

SZL series biomass steam boiler is a horizontal double drum chain grate biomass steam boiler. The main body of the boiler is designed with two drums arranged longitudinally. The upper drum is equipped with a steam-water separation device, and the lower drum is equipped with a timed blowing device. Water-cooled wall tubes are installed on both sides of the furnace. It adopts a light chain grate for automatic fuel feeding. The rear of the furnace is a re-combustion chamber and convection tubes, and the tail of the furnace is a economizer or air preheater. It is equipped with a blower and an induced draft fan for mechanical ventilation, and also has a slag discharge device for automatic slag removal. The fuel falls onto the grate and enters the furnace for combustion. The flue gas passes through the furnace, recombustion chamber, convection tube, economizer or air preheater into the tail flue, then enters the dust collector, induced draft fan and chimney, and is finally discharged into the atmosphere.

Main Feature

1.The two wing flue is set, so that the smoke smoothly into the front smoke box, so that the temperature of the tube plate before the same, to avoid the tube plate cracks caused by temperature stress.
2.The advanced threaded smoke pipe structure improves the heat transfer coefficient of the boiler.
3.The boiler design is reasonable, compact structure, not only easy to disassemble and assemble, but also easy to transport.
4.The boiler adopts the secondary air inlet arrangement, which improves the combustion efficiency and saves the operating cost.
5.The ash after combustion can be used as farm fertilizer, very energy saving.
6.The use of advanced chain grate design, reduce the grate installation, maintenance workload.
