Heze 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-sealed structure, providing tight sealing; easy to disassemble and reinstall the check door with minimal personnel requirements; large pressure relief area, enhancing boiler safety; pressure relief is safe, and the hot gases expelled will not injure personnel. Front and Rear Smoke Boxes Front and rear smoke boxes feature a double-sealed structure for tight sealing. Factory leak test ensures 100% smoke-tightness; smoke box welding is inspected for surface quality to prevent gas leakage, condensation, 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 during operation from cold to hot state, eliminating binding stress for increased safety. Packaging and Insulation Special insulation structure with excellent thermal support and insulation properties. The insulation material uses refractory fiber from "Luyang", the largest manufacturer in the Asian region, resulting in lower skin temperature and reduced surface heat loss.
Performance Features
Design Reasonable: Horizontal internal combustion triple-return full-wet-back design with 100% wave-shaped furnace. Features good thermal expansion. Integrated water包围fire design, with ample heating surface area and reasonable structural arrangement, ensuring high-efficiency operation of the boiler.
Manufacturing Standards: The company has established and reliably operates a comprehensive quality assurance system. The product manufacturing process is fully controlled and supervised by a special inspection agency on-site.
High Efficiency Energy-Saving: The steam and hot water boiler series have thermal efficiencies ranging from 92% to 99.8%. The large combustion chamber combined with rational structural arrangement allows for more heat to be transferred into the water, greatly enhancing the heat exchange capabilities between fuel-steam and fuel-hot water.
Meets environmental protection standards: Large combustion space, fully utilizing radiant heat exchange, and equipped with high-quality and reliable imported burners, ensuring complete combustion of the fuel and significantly reducing the emission of harmful components in flue gas. Our company's fuel (gas) steam and hot water boilers have passed official department testing, comply with national environmental protection requirements, and are ideal eco-friendly products.
High heating quality: Steam boilers feature ample steam storage capacity, ensuring high-quality dry steam even during significant load fluctuations.
Superior Configuration: Equipped with world-renowned burners, advanced control systems (main components are imported), valves, and pumps all using national high-quality products. The excellent boiler accessory configuration provides a strong guarantee for the safe operation of the boiler.
Fully Automatic Operation: With just one press of the start button, the boiler operates according to the set program, with automatic load regulation and water supply, etc., 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 convenience: The boiler is equipped with movable smoke box doors at both front and rear, with observation and inspection holes at the rear, allowing easy access to the furnace chamber for inspection and cleaning. Manholes are provided on the boiler body, with the structural design fully considering ease of maintenance and repair in the future.

Energy Saver: ND Steel Advantages
ND steel is the most ideal steel for "withstanding low-temperature dew point corrosion" both domestically and internationally, widely used in the manufacturing of devices such as economizers (energy savers), air preheaters, heat exchangers, and evaporators that operate in high-humidity flue gases to resist dew point corrosion in flue gases. ND steel also exhibits resistance to chloride ion corrosion. The main evaluation criteria for seamless steel tubes and plates made of 09CrCuSb (ND steel) are that the corrosion rate does not exceed 14mg/cm²·h after soaking in a 70°50% H2SO4 solution for 24 hours, which is 1.84 times that of Japanese 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 dew point corrosion resistance and very high cost-performance ratio of ND steel make it a perfect substitute for stainless steel, and the best material surpassing stainless steel in terms of dew point corrosion resistance. ND steel holds significant economic importance and aligns with the current "green" concept of high efficiency, longevity, energy conservation, and environmental protection, as well as the national development policy orientation. Comparison of 09CrCuSb steel (ND steel) with other steel grades.
Steel Grades: 09CrCuSb (ND Steel), CRIR (Japan), 1Cr18Ni9, Corten, S-TEN (Japan), A3 (Q235B) Corrosion Rates: 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 is a representative steel of the American Cu-P series and belongs to a low-alloy, high-strength atmospheric corrosion-resistant structural steel. In China, it is referred to as weather-resistant steel.
