Shandong Heze Babjehec Boiler Gas Boiler Supplier
Gas boiler structure:
Hekuo gas boilers are currently mainly available in the following types:WNSSeriesSZSSeries.WNSThe series of boilers is primarily composed of the kettle shell and the firebox as the two main components. It features a second and third return threaded smoke tube heating surface, also known as a horizontal three-return boiler. So what is meant by that?“Wet Back” Boilers refer to the transition chamber of the boiler being incorporated into the drum, with the tube plate, back plate, and cylinder of the transition chamber all surrounded by boiler water.(Immersed in furnace water)Therefore, it is referred to as“Wet Back”(Also known as water-backed style)。
CurrentlyWNSThe series of regenerative chambers are all submerged in water, and they are all wet-back boilers. The smoke chambers of dry-back boilers are not fully surrounded by water. Hekou gas boilers use wet-back structures. In addition, to ensure the safe and economic operation of the boiler, auxiliary equipment such as instruments, automatic control, and protection systems are also added.
SZSThe series of boilers belong to the double-drum longitudinal vertical room-type room combustion 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.
Huzhou Boiler Factory Co., Ltd.
Project Notes Explosion-proof Device Top-mounted gravity explosion-proof device with constant opening pressure; explosion-proof door cover with double-sealing structure, tight seal; easy disassembly and reinstallation of the inspection door, low personnel requirements; large relief area, safer boiler; safe during pressure relief, the hot gas ejected will not injure personnel. Front and Rear Smoke Boxes The front and rear smoke boxes have a double-stage sealing structure, ensuring a tight seal; undergo air leakage test upon factory shipment, achieving 100% smoke-tightness; welding of smoke boxes is inspected on the surface to prevent gas leakage, condensation formation, and corrosion of the skin. Boiler Support The support is fixed at one end and slides at the other, allowing the boiler to expand and contract freely from cold to hot operation, eliminating binding stress and ensuring safety. Packaging and Insulation Special insulation structure, with excellent support for insulation effect; uses refractory fiber from the largest manufacturer in Asia, "Luyang," for thermal insulation material, keeping the skin temperature low and minimizing surface heat loss.
Performance Features
Design Reasonable: Horizontal internal combustion triple-return full-wet-back design with 100% corrugated furnace tube. Features good thermal expansion. Integrated water and fire design, ample heating surface area and rational structural arrangement ensure the high-efficiency operation of the boiler.
Manufacturing Standards: The company has established a comprehensive quality assurance system that operates reliably, with the entire product manufacturing process strictly controlled and supervised by a special inspection agency on-site.
High Efficiency Energy Saving: The thermal efficiency of our steam and hot water boiler series ranges from 92% to 99.8%. The large combustion chamber, combined with rational structural arrangement, allows for more heat to be transferred into the water, significantly enhancing the heat exchange capacity between fuel-steam and fuel-hot water.
Meets environmental protection standards: Large combustion space, fully utilizing radiant heat exchange, combined with high-quality and reliable imported burners, ensuring complete combustion of fuel and significantly reducing the emission of harmful components in flue gas. Our company's oil (gas) steam and hot water boilers have passed legal department testing and comply with national environmental protection standards, making them ideal eco-friendly products.
High heating quality: Steam boilers feature ample steam storage capacity, ensuring the supply of high-quality dry steam during significant load fluctuations.
Superior Configuration: Equipped with world-renowned burners, an advanced control system (main components are imported), valves, and pumps all utilize top-quality national products. The excellent boiler accessories configuration provides a strong guarantee for the safe operation of the boiler.
Fully Automatic Operation: With just a push of the start button, the boiler operates according to the set program, with load regulation and water supply all being fully automatic, requiring no constant supervision.
Long service life: The professional design of our boiler products, advanced production technology, and high-quality boiler steel ensure that the normal lifespan of the boiler body is over 15 years.
Maintenance and repair are convenient: The boiler is equipped with movable smoke box doors at both front and back, with observation and inspection holes at the rear, allowing access to the furnace chamber for inspection and cleaning. Manholes are also provided on the boiler body, with the structural design taking into account ease of maintenance and repair in the future.

Energy Saver: ND Steel Advantages
ND steel is the most ideal material for "withstanding low-temperature dew point corrosion" both domestically and internationally, widely used in the manufacture of economizers (energy savers), air preheaters, heat exchangers, and evaporators that operate in high-humidity flue gases, to resist dew point corrosion caused by flue gas condensation. ND steel also has the ability to withstand chloride ion corrosion. The main evaluation criteria for 09CrCuSb (ND steel) seamless steel tubes/plates (immersed in 70° 50% H2SO4 solution for 24 hours) are corrosion rates not exceeding 14mg/cm2·h, which is 1.84 times that of Japan's CR1R steel, 2.97 times that of 1Cr18Ni9 steel, 8.63 times that of Corten steel, and 14.11 times that of Q235B steel, when compared to carbon steel, imported Japanese steel of the same type, and stainless steel in terms of corrosion resistance. The superior corrosion resistance and excellent cost-performance ratio of ND steel make it a perfect substitute for stainless steel, and the best material that surpasses stainless steel in terms of dew point corrosion resistance. ND steel holds significant economic value and aligns with today's "green" concepts of high efficiency, longevity, energy conservation, and environmental protection, as well as with the national development policy orientation. Comparison of 09CrCuSb (ND steel) with other steel grades
Steel Grades 09CrCuSb (ND Steel) CRIR (Japan) 1Cr18Ni9 Corten S-TEN (Japan) A3 (Q235B) Corrosion Rate 7.30 13.40 21.70 63.00 27.4 103.50 Multiples 1 1.84 2.97 8.63 3.75 14.11
Note: Corten steel, also known as weathering steel, is divided into two main categories: Corten A and Corten B. It represents the Cu-P series steel in the United States and is a low-alloy, high-strength atmospheric corrosion-resistant structural steel. In China, it is referred to as weather-resistant steel.
