GAZ TURBINE INSTALLATION AND METHOD OF FUNCTIONING OF GAS TURBINE INSTALLATION Russian patent published in 2017 - IPC F02C3/30 

FIELD: power industry.

SUBSTANCE: gas turbine unit (GTU) contains a compressor, a combustion chamber, a turbine, an energy consumer, a fuel supply line and a waste heat boiler equipped with hot and cold coolant circuits. The hot coolant circuit is made in the form of an exhaust channel of combustion products from the turbine to the atmosphere. The cold coolant circuit is in the form of a countercurrent flow channel with an inlet to the counterflow channel of the fuel supply manifold and the water supply manifold at the inlet, and at the outlet of the steam supply manifold of the mixture of water and fuel into the combustion chamber. The exhaust channel of the combustion products to the atmosphere at the outlet of the turbine is equipped with a series-installed waste heat boiler, a radiator and a water condenser. The counterflow channel of the coolant circuit and the supply manifold of the fuel-water mixture conversion products to the synthesis gas are formed in the form of spiral tubular channels arranged in series along the exhaust duct wall of the waste heat boiler and along the wall of the combustion chamber fire tube. In the way of functioning of the installation in the combustion chamber of the GTU, the products of conversion of the fuel-water mixture into the hydrogen-containing synthesis gas are supplied as fuel.

EFFECT: invention provides fuel economy during incineration and the independence of the plant from external water sources, reduces harmful emissions into the atmosphere and allows the use of gas turbine engines that have worked out their life for a gas turbine plant.
