Ten years of rapid development in chemical engineering technology; praise for the prosperous and strong China. This is just a starting point to encourage more participation from everyone. HaiChuan becomes even better with your involvement – we welcome all to join in the forum discussions. Be careful with fire risks as the heat increases in July. ---------------------------------------------- At the beginning of July 2023, the Lanzhou Petrochemical Equipment Branch of China National Petroleum Bohai Petroleum Equipment Manufacturing Co., Ltd. (referred to as Bohai Equipment Lanzhou Petrochemical Equipment Company) and Wuxi Huatian Gas Turbine Co., Ltd. held a meeting in Lanzhou to evaluate the performance of the “high-efficiency pure hydrogen gas turbine combustor” product. 　　“In close collaboration with Wuxi Huatian Gas Turbine Company, and after nearly 2 years of hard work, we have successfully overcome challenges such as the high risk of fuel spontaneous ignition and high tempering risks. We have developed an ‘efficient pure hydrogen gas turbine combustor’, thereby entering this entirely new field of hydrogen-fueled gas turbines. ”According to Zhang Yong, manager of Bohai Equipment Lanzhou Petrochemical Equipment Company, the company leverages its technical expertise in high-temperature turbines and special high-temperature valves to collaborate with Wuxi Huatian Gas Turbine Company on the research and development of hydrogen combustion chambers for gas turbines. By taking into account the combustion characteristics of hydrogen, the combustion chambers of existing turbine models are optimized to accommodate factors such as the shorter ignition delay time, higher flame propagation speed, unstable combustion, and high combustion temperatures associated with hydrogen. 　　It is understood that Bohai Equipment, Lanzhou Petrochemical Equipment Company, and Wuxi Huatian Gas Turbine Company have initially tested the pure hydrogen combustion technology, and completed experimental verification of a combustion configuration using 100% hydrogen. “We are currently conducting verification tests on dry low-emission hydrogen combustion technologies using lean premixed fuel and micro-mixing methods. It is expected that component-level tests will be completed by 2024, while full-scale tests and demonstration operations will take place in 2025, thereby laying a technical foundation for the large-scale commercial use of domestically produced low-emission pure hydrogen engines in the future. ”said Lu Gang, the company’s chief engineer.
