Gas boiler structure:

   Hebei Gas-Fired Boilers currently mainly have:WNSSeriesSZSSeries.WNSThe series of boilers is mainly composed of two major components: the drum and the firebox. It features a second and third return threaded flue tube heating surface, also known as a horizontal three-pass boiler. What is meant by...“Wet Back” Boilers refer to a design where the smoke chamber of the boiler is incorporated into the drum, with the tube plate, back plate, and cylinder all surrounded by the boiler water.(Immersed in furnace water)Therefore, it is referred to as“Wet Back”(Also known as water-backed style)。
   CurrentlyWNSThe regenerative chambers in this series are all submerged in water, making them wet-back boilers. The dry-back boilers do not have a smoke chamber fully enclosed in water. The Hekou gas boilers use a wet-back structure. Additionally, to ensure safe and economic operation of the boiler, auxiliary equipment such as instruments, automatic control systems, and protection systems are also added.

    SZSThe series of boilers belong to the double-drum vertical chamber type fire-tube boilers. These boilers are of the upper and lower drum type 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.

Energy-saving effect of gas boilers is much better compared to other types of boilers. Gas boilers account for a high proportion in developed countries like Europe and the US. Due to historical reasons, coal-fired boilers dominate in our country. With the severe air pollution in recent years, especially in the Beijing-Tianjin-Hebei region, as well as Shandong, Shanxi, and Henan, smog during winter is extremely severe, severely affecting people's health. With widespread attention from all sectors of society, the understanding of smog has deepened, and the "Coal-to-Gas" project has been vigorously implemented as a sharp sword.Shandong Hezhou PotBoilers are also actively stepping up production with high-quality, energy-saving, and environmentally friendly gas boilers.
