SZL series boilers are designed by our company's technical staff according to domestic and foreign advanced technology and experience designed horizontal double drum vertical set of chain furnace drain steam and hot water boilers. The technical, performance and environmental protection indicators of this series have reached the international advanced level and are the leading products of the boiler industry.

　　Boiler adopts quick assembly or assembly structure. 4~6t/h is a quick-fill water pipe structure, which is delivered after the whole assembly in the factory; 6-35t/h is composed of two large and small parts. The upper part is the main heating surface, and the lower part is the combustion equipment. The front end of the boiler body is the upper part of the water wall, which is arranged around, and the lower part of the connection between the water drum and the header forms a combustion chamber to absorb the radiant heat of the furnace. The rear end of the boiler is arranged with dense convection tube bundles between the upper and lower drums, and the high-temperature smoke after combustion. After the gas passes through the secondary return stroke, the convective heating surface is laterally directed to the separately arranged economizer, and finally the dust collector is discharged through the chimney. The 20tb assembled water pipe saw furnace is composed of a forehearth, a post furnace, a convection pipe east, a governor, and a chain grate, and the wells are separately assembled to leave the factory.

　　This series of boilers draws advantages from quick-loading boilers, with a compact structure, single-layer arrangement of boiler furnaces, convenient on-site installation, short cycle time, low usage, and easy operation. This series of steam boilers is suitable for industrial and domestic use. The corresponding capacity of water heaters is suitable for industrial and civil heating.
