Well-designed:
Horizontal internal combustion three-return full wet-back design100%Wavy furnace tube,Excellent thermal expansion properties. The water-in-fire overall design, with ample heating surface area and reasonable structural arrangement, ensures the high efficiency operation of the boiler.
High-efficiency and energy-saving:
Steam and hot water boiler series all have high thermal efficiency of97%-99%The spacious combustion chamber, combined with rational structural arrangement, allows more heat to be transferred into the water, greatly enhancing the heat exchange efficiency between fuel and steam, as well as fuel and hot water.
Meets environmental requirements:
The combustion chamber is spacious, maximizing radiant heat exchange, and coupled with a high-quality, reliable imported burner, it ensures complete combustion of the fuel, significantly reducing harmful emissions in the flue gas. Our company's fuel (gas) steam and hot water boilers have been tested and meet national environmental protection standards, making them ideal eco-friendly products.
Superior configuration:
World-renowned burner compatibility, advanced control systems (with imported main components), valves, and pumps are all made with national top-quality products. An excellent boiler accessory configuration ensures the safe and stable operation of the boiler.
Fully Automated Operation:
Users simply need to press the start button, and the boiler will run according to the set program. Load regulation, water supply, and other operations are all fully automated, requiring no constant supervision.
Easy maintenance and repair:
Boilers are equipped with removable ash box doors at both front and rear. The rear features observation holes and inspection ports, allowing for entry into the furnace for inspection and cleaning. A manhole is also provided on the boiler body, with a structural design that considers ease of maintenance and future repairs.
Principle of Operation for Gas Boilers:
Water in the pot (pot shell) is continuously heated by the energy released from the combustion of gas fuel in the furnace. As the temperature rises, it produces pressurized steam. Since the boiling point of water increases with pressure, the pot is sealed, and the expansion of steam inside is restricted, creating pressure to form thermal power (strictly speaking, the steam in the boiler is formed by water being heated to saturation in the pot shell at a constant pressure and then vaporizing). As an energy source, it is widely used.
Gas boiler structure:
Hekou gas boilers are currently mainly available in the following types:WNSSeriesSZSSeries.WNSThe series of boilers is mainly composed of two major components: the boiler shell and the furnace tube. The design includes the second and third return螺纹烟管 heating surfaces, also known as horizontal three-return boilers. What is meant by that is...“Wet Back” A boiler refers to a type of boiler where the smoke chamber extends into the drum interior, with the pipe plate, back plate, and cylinder of the smoke chamber all surrounded by boiler water.(Immersed in furnace water)Therefore, it is referred to as“Wet Back”(Also known as waterback style)。
CurrentlyWNSAll the regenerative chambers in the series are submerged in water, making them wet-back boilers. The smoke chambers of dry-back boilers are not fully surrounded by water. Hebei gas boilers use a wet-back structure. Additionally, to ensure the safe and economic operation of the boiler, instruments and auxiliary equipment, automatic control, and protection systems are also added.
SZSSeries boilers belong to the double-drum longitudinal chambered fire-tube boilers. These boilers are of the type with water-cooled walls, featuring upper and lower drums connected by a downcomer and water-cooled wall tubes, forming the framework of the combustion chamber. The upper part of the drum is equipped with a steam-water separator to reduce the amount of water carried away by steam. The heating surface of the drum is the lower part, with water-cooled wall tubes and flue tubes, separated by a membrane-type wall between the water-cooled walls to create a smoke return path. Generally suitable for large tonnage or working pressure≥1.6MPaOven type
