SZL series 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.
Boiler is manual operation boiler which adopting manual fuel feeding, manual slag removing. The fuel can be firewood, wood logs, biomass pellets, peanuts shell, grain shell, etc. Equipped with special dust collector solution (water film dust collector, bag type static electricity dust collector, double towers desulfurization, etc.), it can realize automatic fuel feeding, automatic ash removing. It is the most popular products in Southeast Asia, Central Asia, Africa.
Classical Structure
Advanced Structure: SZL boiler adopting threaded fire tubes, single water drum, horizontal shell type boiler with 3 fire-passes structure, water-tube fire-tube mix design. Comparing with DZL series boiler, SZL series boiler has better adaptability on fuels, it can fire coal, rice husk, nut shell, sawdust, waste wood pieces, also can fire wood logs, straws. But, DZH boiler can only support manual fuel feeding, and manual ash remove.
High Quality Control
High Quality Control: In manufacturing processes, we has adopting steel strength test, automatic steel cutting/ plate rolling/ welding, 100% x-ray welding check, magnetic particle check c-scan ultrasonography Ultrasound check, fluorescent penetrating check, hydraulic (water) pressure test, boiler thermal efficiency test,etc, to make sure all finished products is qualified.
Low Fuel & Labor Cost
SZL boiler can firecoal, rice husk, nut shell, sawdust, waste wood pieces, also can fire wood logs, straws. This will markedly reduce user’s fuel consumption cost, increase company’s benefits. Only need 1 worker to operate the fuel feeding and slag removing.
