FIELD: machine building; heating engineering.
SUBSTANCE: invention relates to machine building and heating engineering, namely to preparation means of fuel gas. Aggregate gas-oil unit is located in a separate transportable frame and contains gas filter skids, gas flow meters, two connected consistently among themselves gas-oil heat exchangers and additional gas-oil heat exchanger for heating start-up gas. Between consistently connected gas-oil heat exchangers pressure reducer valve and generator with gas reduction function is installed. Alternatively, aggregate gas-oil unit contains gas filtration units, gas flow meters, two connected consistently among themselves gas-oil heat exchangers and additional gas-oil heat exchanger for heating start-up gas. Between consistently connected gas-oil heat exchangers pressure reducer valve and generator with gas reduction function is installed. At the same time and in addition, to the output of gas-oil heat exchanger, which uses hot oil of gas turbine drive of GPA as a heating coolant, fuel gas electric heater is connected in series.
EFFECT: increase efficiency of GPA.
