FIELD: mechanic, energetic. ^ SUBSTANCE: invention refers to heat power industry, in particularity to combined cycle gas turbine. In the proposed combined cycle gas turbine of the thermal electric station it is used the possibility of utilization of thermal gas energy, overworked in gas turbine. The process of utilization of thermal energy it is done through blading section of gas turbine under direction of gas stream to radial canals and/or hollows, generated in nozzle blades of steam turbine stages of cylinder of low pressure. The overworked gas, destined for utilization to the construction elements (nozzle apparatus) of turbine, is working under regime of utilization vapor-generator. The increasing of parameters of low-temperature vapor in blading section, and exclude the possibility of generating of coarse damp and initiate increasing of work efficiency of gas turbine and its reliability in exploitation conditions, especially in no calculable regimes under decreasing of the start parameters of vapor on the inlet to the turbine. The using of thermal energy in the heaters of feeding, net water and vapor of industrial selection instead of energy of high-temperature vapor which initiate the increasing of power of vapor turbine, and accordingly, the generator of electrical energy in integral system of gas-vapor unit of thermal electrical station. The invention allows to increase the efficiency of thermal electrical station work. ^ EFFECT: it is increased the efficiency of thermal electrical station work. ^ 3 cl, 1 dwg |
