SZL Series Hot Water Boiler Introduction
SZL series coal fired 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 SZL series hot water boiler 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.
SZL Series Hot Water Boiler Advantages
- SZL series double-drum longitudinal-type chain furnace drain hot water boiler adopts quick assembly or assembly structure. 2.8~4.2MW is the structure of quick-loading water pipe, which is factory-installed after being completely assembled in the factory; 4.2~29MW is composed of two upper and lower parts, the upper part is the body heating surface, and the lower part is the combustion equipment.
- The front end of the boiler body is surrounded by the upper part of the water-cooled wall and the lower part of the drum is connected with the header to form a combustion chamber to absorb the radiant heat of the furnace. And the rear end of the boiler is arranged with a dense convection tube bundle between the upper and lower drums, and the high-temperature smoke after combustion
- After passing through the second return stroke. The gas is flushed to the convective heating surface and then led to the separately arranged economizer, and finally enters the dust collector and is discharged through the chimney.
- The boiler body of this series is designed with double boiler barrel, single layer layout, compact structure, large heating area, boiler heating surface 10% more than similar products, with full output, safe and reliable, short construction period, low installation cost and so on.
- The SZL series hot water boiler is equipped with cyclone combustion chamber, which reduces the dust content of flue gas. At the same time, the hot carbon black particles are further burned, which improves the boiler thermal efficiency and reduces the blackness of flue gas. The concentration of soot emission meets the requirements of a class of environmental protection areas.
- The small roller structure and the patented technology of side grate are adopted to improve the reliability of boiler operation.
- SZL series coal fired boilers adopt airtight chamber and two – sided grate air – adjusting device. At the same time, the cone sealing structure is machined, which improves the sensitivity of furnace exhaust air adjustment.
