PROBLEM TO BE SOLVED: To provide a compact city gas pressure regulating installation for a micro gas turbine, wherein high pressure city gas is depressurized to predetermined pressure to be supplied to the micro gas turbine, allowing stable heating of the city gas before depressurized. SOLUTION: The high pressure city gas supplied from a city gas supply line is heated up to a preset temperature using a heat exchanger 5 for heat exchange between hot water supplied from the micro gas turbine 3 and itself. It is depressurized to the predetermined pressure by a first governor 6 and a second governor 7, and then it is supplied to the micro gas turbine 3. COPYRIGHT: (C)2004,JPO&NCIPI
