Finding a reliable Industrial Steam Boiler Supplier means looking beyond the price tag. It requires a partner who understands how a boiler performs after 8,000 hours of running, not just on the day of installation. At Hebei Xiangyi Mechanical, we build and deliver complete steam boiler systems for board production lines, such as calcium silicate board and gypsum board lines. Our units operate in real-world plants across Central Asia, Southeast Asia, the Middle East, and Africa. This page explains what you can expect from our equipment, from material specs to on-site service.
Product Overview: Built for Continuous Production
Our industrial steam boiler is designed for factories that need steady heat and pressure, 24 hours a day, 7 days a week. Unlike residential or small commercial units, this boiler uses a three-pass wet-back structure combined with a condenser at the exhaust end. This design lowers the exhaust gas temperature to approximately 70°C (158°F), recovering latent heat that would otherwise escape up the stack. The result is measurable fuel savings, month after month, without changing your daily operations.
Why this matters to you
A lower exhaust temperature means less fuel burned for the same heat output. For production lines running two shifts or more, the difference covers operational costs clearly within the first year. The condenser also captures condensate from flue gas cooling, reducing visible plume and cutting pollutant emissions (PM2.5, CO, SO, NOx) below local limits in most regions.

Material, Design, and Construction Details
The condenser uses ND steel finned tubes. This material resists sulfuric acid dew-point corrosion and low-temperature corrosion. In actual projects in Uzbekistan and Indonesia, these tubes have survived over eight years without replacement, even with high-sulfur fuels.
Where the flue gas pipe meets the tube sheet, we use gap-eliminating expansion welding. This is not standard tack welding. It prevents tiny cracks from temperature swings between day and night shifts. Many unplanned shutdowns start from these small cracks – we designed our process to avoid them.
The chamber is oversized relative to typical designs, which allows fuel to burn more completely (resulting in lower CO and unburned fuel), provides a wider safe water level range to reduce the risk of dry-run damage, and maintains higher thermal efficiency even when the load changes quickly.
Instead of smooth pipes, we use threaded smoke pipes inside the boiler shell. The threads create turbulence, which breaks the boundary layer of hot gas. This pulls more heat into the water. Compared to bare pipes, our pipes transfer 1.5 to 2.1 times more heat over the same surface area. It also reduces ash buildup and air leakage.
Applications: Where Our Boilers Work
Our steam boilers are not general-purpose units. They are matched to production lines we know well:
Gypsum board production lines – stable steam for drying and setting
Calcium silicate board lines – consistent pressure for autoclave curing
Fiber cement board lines – humidity and temperature control
Mineral wool board lines – steam for bonding and shaping
Mortar mixing stations – heating aggregates and maintaining mix temperature
Example from our records
In 2010, we supplied an 8 million sqm/year gypsum board line in Uzbekistan. The boiler room is located at 400m altitude, with winter ambient temperatures dropping to -15°C. Our boiler maintained output without freeze protection failures, thanks to the automatic purge cycles and low-water protection. That line is still running today, with the same pressure vessel.
Hebei Xiangyi Mechanical Co., Ltd. was founded in 2002. We started as a general mechanical design and manufacturing firm with 100+ employees and 50+ processing machines. Over 22 years, we specialized into complete production lines for building materials, and the boilers that power them.

FAQ (Frequently Asked Questions)
1. What exactly is an industrial steam boiler for board production?
+
-
An industrial steam boiler is a closed pressure vessel that heats water into steam using fuel (gas, oil, or dual fuel). For gypsum board or calcium silicate board lines, the steam is used in drying, curing, and forming stages. Unlike a power plant boiler, ours is designed for stable medium pressure (typically 0.8–1.6 MPa) over long hours, with frequent small load changes as the production line speeds up or slows down. The condensing type adds an extra heat exchanger to recover latent heat from flue gas.
2. How does a condensing steam boiler actually save fuel?
+
-
A non-condensing boiler loses about 15–20% of its heat out of the stack as hot vapor (mainly water vapor from combustion of hydrogen in fuel). A condensing boiler adds a large surface area condenser at the exhaust. When the flue gas temperature drops below about 60–70°C, water vapor condenses and releases its latent heat back into the system. For every 1°C drop in exhaust temperature, efficiency rises roughly 0.02–0.03%. Dropping from 180°C to 70°C is not just 110°C difference – it recovers the phase-change energy, giving a real-world efficiency gain of 5–8% on natural gas. That means 5–8% less fuel for the same production.
3. How does your three-pass wet-back design compare to a two-pass dry-back boiler?
+
-
Three-pass means flue gases pass through the boiler three times before exiting, extracting more heat per cubic meter of gas. "Wet-back" means the reversing chamber is surrounded by water, not refractory brick. Wet-back designs run cooler externally, have less thermal stress, and do not need brick replacement every 2–3 years. Dry-back boilers often develop cracks at the tube sheet because of uneven heating. Our three-pass wet-back structure also has a fully corrugated furnace liner, which expands and contracts without cracking. Customers in Ukraine and Russia have reported no tube sheet cracks after 8+ years.
4. Where have you installed these boilers in real production lines?
+
-
We have operating boilers in Uzbekistan (8 million sqm gypsum board, running since 2010), Indonesia (5 million sqm, since 2009), Russia (Kazan, 3 million sqm since 2007), India (8 million sqm since 2008), Bangladesh, Belarus, Tajikistan, Pakistan, Iran, Iraq, Kuwait, and many provinces in China. Some have been running over 15 years with only standard maintenance (burner service, gasket changes, water treatment). We keep records of each installation and can connect you with past buyers for reference.
5. Can you help if our factory has low or inconsistent fuel gas pressure?
+
-
Yes. Our control system includes high and low gas pressure protection and leak detection. If your site has fluctuating supply, we can specify a burner with a larger gas train or add a gas booster. We ask for your local gas pressure range during the pre-sale stage. For example, a client in Bangladesh had winter gas pressure dropping below 30 mbar. We switched to a dual-fuel burner (gas + LPG backup) and added a small buffer tank. The line never stopped. We do not guess – we design based on your actual conditions.
Tell us your current boiler fuel consumption and production volume. We will calculate the potential savings with our high-efficiency design - typically 8-15% lower fuel use compared to older units.
