Energy-saving effect of gas boilers is significantly better compared to other types of boilers. Gas boilers account for a high proportion in developed countries like Europe and the U.S. In China, due to historical reasons, coal-fired boilers dominate the market. In recent years, with the severe air pollution in China, particularly in the Beijing-Tianjin-Hebei region and Shandong, Shanxi, and Henan provinces, winter smog has been extremely severe, severely impacting people's health. With widespread public attention and deeper understanding of smog, the campaign to protect blue skies has been intensifying, and the "coal-to-gas" project is a sharp sword in this battle.Shandong Hezhou PotBoilerAs early as 2003Actively produce high-quality, energy-saving, and environmentally friendly gas boilers.

Fully Automatic Operation:
With just a press of the start button, the boiler operates according to the set program, with load regulation and water supply all running automatically; no need for constant supervision.
Easy maintenance and repair:
Boilers are equipped with removable smoke box doors at both front and back, featuring observation and inspection openings at the rear for easy access to the furnace chamber for cleaning. The boiler body features a manway, with the structural design meticulously planned for convenient maintenance and future repairs.
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-sealing structure, providing tight sealing; easy to disassemble and reassemble the inspection door, low personnel requirements; large pressure relief area, enhancing boiler safety; pressure relief is safe, the hot gas sprayed out will not harm people. Front and Rear Smoke Boxes The front and rear smoke boxes feature a double-stage sealing structure, ensuring tight sealing. Factory-leakage test is conducted to ensure 100% smoke-tightness; welding of smoke boxes is inspected on the surface to prevent smoke leakage, condensation water 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 during operation from cold to hot, eliminating束缚 stress, and ensuring greater safety. Packaging and Insulation Special insulation structure with excellent support for insulation effect. The insulation material uses refractory fiber from "Luyang", the largest manufacturer in the Asian region, keeping the skin temperature low and minimizing surface heat loss.

Energy Saver: ND Steel Advantages
ND steel is the most ideal steel for "resistance to low-temperature dew point corrosion" both domestically and internationally. It is widely used in the manufacturing of devices and equipment such as economizers (energy savers), air preheaters, heat exchangers, and evaporators that operate in high-humidity flue gas environments, to combat dew point corrosion in flue gas. ND steel also exhibits resistance to chloride ion corrosion. The main evaluation criteria for 09CrCuSb (ND steel) seamless steel pipes/plates (soaked in 70° 50% H2SO4 solution for 24 hours) are that the corrosion rate does not exceed 14mg/cm2·h, 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, compared to carbon steel, imported Japanese steel of the same type, and stainless steel in terms of corrosion resistance. ND steel's superior resistance to dew point corrosion and its very high cost-performance ratio make it a perfect substitute for stainless steel and the best material to surpass stainless steel in terms of dew point corrosion resistance. ND steel holds significant economic value and aligns with the current "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 Cor-Ten 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 low-alloy high-strength atmospheric corrosion-resistant structural steel, known as weather-resistant steel in China.
