Project Overview
A petrochemical plant, covering approximately 1,400 square meters, has introduced two advanced 75-ton medium-temperature and medium-pressure boilers from Fangkuai Boiler. These units efficiently utilize by-product hydrogen generated during the production of key chemicals such as Methyl Tert-Butyl Ether (MTBE) and Ethylbenzene.
Challenge
Previously, the plant faced significant underutilization of by-product hydrogen—a valuable resource produced in large volumes daily. This not only represented a wasted energy opportunity but also added to operational inefficiencies.
Solution
Fangkuai Boiler provided a turnkey solution by leveraging its advanced fuel adaptability and precise combustion control technology. The two 75-ton boilers were designed to operate efficiently using by-product hydrogen as a primary fuel, transforming it into a clean and reliable source of steam power.
Key Advantages & Outcomes
Exceptional Thermal Efficiency ≥99%
Compared to conventional boilers in the industry, which average around 95% efficiency, Fangkuai’s boilers achieve thermal efficiency of ≥99%. This high-efficiency performance reduces natural gas consumption significantly, saving the plant tens of thousands of RMB daily.
Fast Deployment & Modular Design
The boilers were delivered in modular sections, allowing easy transportation and quick on-site assembly. By simplifying installation—mainly involving pipeline connection—the project timeline was shortened by over 70%. This acceleration enabled earlier commissioning, contributing to higher production output and notable savings in time-related costs.
Economic & Operational Benefits
Daily fuel savings from high-efficiency hydrogen combustion.
Reduced external energy procurement costs.
Increased operational availability thanks to shorter installation time.
The combined value from early production ramp-up and ongoing fuel efficiency surpasses the savings from fuel alone on a daily basis.

Conclusion
By adopting Fangkuai Boiler’s hydrogen-fired boiler solution, the petrochemical plant has turned a waste by-product into a high-value energy resource. The project highlights how innovative boiler technology can enhance sustainability, lower operating costs, and improve overall productivity in energy-intensive industries.
Fangkuai Boiler's hydrogen solution helped a petrochemical plant reach ≥99% efficiency, use by-product hydrogen as fuel, cut installation time by 70%, and save thousands daily. Turn waste into energy!
Qingdao, China — Autumn 2025 — FangKuai Boiler Co., Ltd. made a striking appearance at the 67th National Pharmaceutical Machinery Expo & China International Pharmaceutical Machinery Expo held in Qingdao. As a leading name in industrial boiler technology, FangKuai’s booth at Hall CW-9 (West Entrance) drew steady crowds and emerged as one of the event’s standout attractions.
FangKuai’s 75T “Lego” modular boiler ships as factory-assembled modules that stack on site for fast installation, a smaller footprint and easier maintenance. Key features include a top-mounted large steam drum for better steam quality, a flattened low-profile layout to cut vibration risk, and a straight-path wing-tube condensation design for low resistance and efficient heat recovery.
