FIELD: gas-turbine plants.
SUBSTANCE: proposed method of cooling of hot units of gas-turbine plants, for instance, turbine plants of gas-transfer sets, includes taking air from several zones of gas-turbine plant, forming air flows and dividing them into separate cooling flows for each object. Air taken from several zones of gas-turbine plant is brought out of the limits of engine. Flows are grouped into cooling groups of flows for groups of object with similar parameters. Flows are additionally cooled and are divided into separate flows with required pressure before delivering to each object separately. Each air flow is cleaned by separate air cleaner to required degree of cleanness and then is delivered to object to be cooled.
EFFECT: reduced consumption of air taken for turbine cooling, improved efficiency of cooling of hot units.
