The design and manufacture of the furnace body adopts three return wet back type eccentric furnace with asymmetric structure. The furnace can be designed in a waveform to reduce the thermal expansion stress and increase the radiant heating surface. Advanced digital control technology is adopted to realize remote monitoring of combustion process. Fully automatic, a variety of guarantee perfect. Selection of high quality imported low NOx burners, full combustion, environmental protection products. Choose condensing heat exchanger and air preheater, hot water boiler to improve boiler efficiency. The communication interface can be attached to realize the control of the upper computer. In strict accordance with the relevant national standards to manufacture boiler production specifications. Machine quick assembly factory, beautiful appearance, bright color.

Fully automatic oil-gas steam boiler, all use shell three return full wet back steam boiler.

... The fuel oil is burned under a small positive pressure in the furnace, and the high temperature flue gas enters the flue tube bundle through the return chamber along the back of the furnace tube, and the steam boiler enters the second flue tube bundle through a 180° turning point through the front chimney, and is discharged into the atmosphere through convection heat transfer.

A three-return steam boiler with large capacity is designed by using the design idea of central symmetrical three-return structure. This is the characteristic of boilers.
