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.
Product features:
SZL series pressure double drum chain grate biomass hot water boiler, boiler host design as double boiler drum longitudinal layout, set steam water separating device in upper boiler drum, set periodic blow-off device in lower boiler drum, there are water cooling wall tubes at left and right side of furnace.
Use light chain grate add fuel automatically, the back of furnace is re-burning chamber, convection tubes, the tail of furnace is economizer or air preheater, equip with blower, draft fan for mechanical ventilation, and also equip with slag extractor for slagging automatically. Fuel fall down to chain grate and enter furnace for burning, the flue gas go through furnace, re-burning chamber, convection tubes, economizer or air preheater into tail flue, enter deduster, draft fan and chimney, and finally discharge into atmosphere.
