METHOD TO UTILISE HEAT OF EXHAUST GASES OF GAS-TURBINE PLANTS Russian patent published in 2011 - IPC F02C7/10 

FIELD: power engineering.

SUBSTANCE: method to utilise heat of exhaust gases of gas-turbine plants consists in removal of heat from exhaust gases of the gas-turbine plant and its utilisation to heat cycle air in regenerator and water of hot water supply - in water heater. When demand in hot water supply seasonally reduces, the internal line of the water heater is disconnected from the direct and return manifolds of heating-system water, water inside the pipes is drained, cleaned and dried with "hot" compressed air arriving from the compressor. The internal line of the water heater is sealed and connected in parallel to the air line of regenerator to manifolds of compressed air supply/discharge. Water heater heat exchanger surface is used to heat cycle air, mixing it with air heated in the regenerator, and the produced mixture is sent in the combustion chamber of the gas-turbine plant.

EFFECT: increased efficiency of fuel usage for the whole period of the gas-turbine plant operation.
