SZL series boiler is the horizontal dual cylinder arranged,chain grating,pipe steam and hot water boiler designed by our technical personnel according to advanced technology and experiences from home and abroad.The technology performance and environmental protective index of this series of products reach the international advanced level,and this product is the mainstay one in boiler industry.
The boiler uses quick fitting or assembly structure.The 4-6 t/h boiler is of quick fitting pipe structure,exit shop after completely assembled,the boiler of 6-35 t/h is composed of 2 main components: The upper assembled components is the body heat accepting part, and the lower assembled component is of combustion equipment. The former part of the boiler body is arranged an water cooling 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 pipe bundle 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.The 20 t/h assembled water pipe boiler is composed of front furnace, rear furnace, convection pipe bundle,coal saver and chain grating,and which are assembled in big components respectively for delivery.
This series of boiler absorbs the merits from quick fitting boiler, features compact in structure,the boiler's shop is of one storey arranged,convenient for site installation,short in construction period, cheap in cost, simple in operation and etc.This series of steam boiler is suitable for isustrial and living steam consumption,the correspondent capacity hot water boiler is applied for industrial and civil heating purpose.

01CNC manufacturing technology
02Advanced welding process
|The welding of important parts like the vertical and circular seams of the boiler, the pipes, the inside of boiler and the flange are all adopted automated welding processes such as submerged arc welding or gas shielded welding to ensure the welding quality. All the vertical and circular seams will be done 100% radiographic inspection.|
03Tube flange weld adopts robot welding.
|The chain grate panel, front and rear smoke chamber panel adopts CNC plasma cutting machine to cut orderly and beautifully.|
04Unique structural design
