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 inspection door, low personnel requirements; large relief area for increased safety of the boiler; safe during pressure relief, hot gases expelled will not harm people.    Front and Rear Smoke Boxes    The front and rear smoke boxes feature a double-stage sealed structure for tight sealing. They undergo air leakage tests before shipment to ensure 100% smoke-tightness; welding is inspected on the surface to prevent smoke 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, eliminating restraint stress for enhanced safety.    Packaging and Insulation    Special insulation structure with excellent support for insulation effect; uses refractory fiber from "Luyang," the largest manufacturer in the Asian region, for insulation materials, resulting in lower skin temperature and reduced surface heat loss.

Energy Saver: ND Steel Advantages

ND steel is currently the most ideal steel for "withstanding low-temperature dew point corrosion" both domestically and internationally. It is widely used in the manufacture of devices such as economizers (energy savers), air preheaters, heat exchangers, and evaporators that operate in high-sulfur flue gas environments to resist dew point corrosion in flue gas. ND steel also exhibits resistance to chloride ion corrosion. The main assessment criteria for 09CrCuSb (ND steel) seamless steel tubes/plates (immersed in a 70°50% H2SO4 solution for 24 hours) show corrosion rates not exceeding 14mg/cm2·h. Compared to carbon steel, Japanese-imported similar steel, stainless steel, and corrosion resistance, it is 1.84 times more resistant than Japanese CR1R steel, 2.97 times more resistant than 1Cr18Ni9 steel, 8.63 times more resistant than Corten steel, and 14.11 times more resistant than Q235B steel. ND steel's superior dew point corrosion resistance and very high cost-performance ratio make it a completely viable substitute for stainless steel and the best material to exceed stainless steel in dew point corrosion resistance. ND steel holds significant economic value and aligns with the current "green" concepts of high efficiency, long life, energy saving, and environmental protection, as well as with the national development policy orientation. Comparison of 09CrCuSb (ND steel) with other steel grades.

Steel Grade 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 Multiplier 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 structural steel with excellent atmospheric corrosion resistance, known as weather-resistant steel in China.

Heze Boilers  Gas Boilers  Natural Gas Boilers  Gas Steam Boilers

Fully Automatic High-Efficiency Energy-Saving Gas Steam Boiler

I. Principle of Boiler Operation:

    WNThe S series fuel (gas) steam boiler is a quick-assembly internal combustion boiler that employs a high-performance fully automatic burner as the primary combustion equipment. It generates a high-temperature flame through the automatic ignition function, which exits the boiler via the upper flue outlet and is discharged into the atmosphere through the chimney. This type of boiler boasts high heat exchange efficiency, simple structure, and a long service life.

II. Features of the Boiler Body:

1. Constructed with high-quality boiler steel plate, in compliance with the national JB/T10393 standard.

2. Utilizes a pipeline through-flow structure, offering high heat exchange efficiency and a long service life.

3. Boilers' weld seams 100% X-ray inspected and accompanied by a certificate of compliance.

4. Utilizes high-quality, efficient thermal insulation materials with minimal heat loss.

3. Features of Boiler Electrical Control System:

Pressure Limiting Full-Automatic Control Device

2. Automatic safety valve exhaust device

3. High or low water level, trigger an alarm and immediately stop heating.

4. Overcurrent shutdown and alarm

Principle of Operation for Gas-Fired Boilers:

Water in the pot (pot shell) is continuously heated by the energy released from the combustion of gas fuel in the furnace, causing the temperature to rise and producing pressurized steam. As 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.
