Two Technologies from a Dalian Company Selected for the 2025 National "China Good Technology" Program

Deep News10-27 00:10

Recently, the China Association of Productivity Promotion Centers released the selection results for the 2025 national-level "China Good Technology" project database, and two technologies independently developed by Dalian Paisi Gas Equipment Co., Ltd. were successfully included in the Category C project database, fully demonstrating the innovative competitiveness of Dalian enterprises in the field of hydrogen-blended natural gas.

The technologies selected from Dalian Paisi Gas Equipment Co., Ltd. are the "Natural Gas and Hydrogen Blending Power Generation Gas Filtration and Mixing System" and the "Natural Gas and Hydrogen Blending Power Generation Gas Preheating System."

These two technologies are mainly applied to the front-end modules of gas turbines in gas-fired power plants, and can significantly optimize the operational efficiency and safety of hydrogen-blended power generation. Among them, the gas filtration and mixing system greatly improves the uniformity of the mixed gas and the precision of dynamic proportioning, while reducing the concentration non-uniformity coefficient of the mixture by 5% compared with traditional equipment; the gas preheating system can precisely control the blending temperature, with heat exchange efficiency increased by 15% and the hydrogen blending ratio raised to 20%.

This selection is an affirmation of Dalian Paisi Gas Equipment Co., Ltd.'s years of tackling technical challenges, and marks that the technical advantages of Dalian enterprises in the field of hydrogen-blended natural gas have received national-level recognition.
