Scope
GB/T 41148-2021 is the English-translated version of 气体燃料发电机组通用技术条件.
GB/T 41148-2021 sets the general requirements for generating sets fuelled by natural gas, biogas and other gases, with a rated voltage of 15 kV or less and a rated frequency of 50 Hz.
Its technical requirements cover the matching of the set, environmental conditions, installation, power ratings and operating modes, starting and gas supply, performance limits, temperature rise, protection devices, heat or gas consumption, structure, limits for environmental pollution, tightness, safety, reliability and maintainability, completeness and marking.
It then sets the inspection items, classification, sequence and conditions, the identification, type, factory and acceptance inspections, and the inspection methods, and ends with packaging and storage.
Sets for other gas fuels, voltages or frequencies can use it for reference. It was issued on 31 December 2021 and has applied since 1 July 2022.
