Gas boiler structure:

   Hekou Gas-Fired Boilers are currently mainly:WNSSeriesSZSSeries.WNSSeries boilers are primarily composed of the drum and the firebox as the two main bodies, featuring a second and third return螺纹tubing heating surface, also known as horizontal three-return boilers. What is meant by that is...“Wet-back style” Boilers refer to the transition of the smoke chamber into the interior of the drum, where the tube plate, back plate, and cylinder of the smoke chamber are all surrounded by boiler water.(Immersed in furnace water)Therefore, it is referred to as“Wet Back Style”(Also known as water-backed style)。
   CurrentlyWNSAll the regenerative chambers in the series are submerged in water, making them wet-back boilers. The dry-back boilers, however, do not have a fully submerged flue chamber. Hekou gas boilers use a wet-back structure. Additionally, to ensure the safe and economic operation of the boiler, instruments and auxiliary equipment, as well as automatic control and protection systems, are also added.

    SZSSeries boilers belong to the double-drum longitudinal flue-tube type room combustion boilers. These boilers are upper and lower drum boilers with water-cooled walls. Between the drum and the lower header, there are downcomers and water-cooled wall tubes, forming the framework of the combustion chamber.
