SZL series coal-fired hot water boiler Hot water Product thermal capacity: 2.8-29 MW Working pressure: 1.0-1.25 MPA Outlet temperature: 95/70℃, 115/70℃ Available fuel: Bituminous coal, lean coal, anthracite Available industries: Heating, hotels, schools, hospitals Introduction SZL series vertical dual drums chain grate water tube 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. Technical advantages • 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. • Automatic production line.
