Description

This invention relates to combined gas and steam turbines using a hollow shaft as a combustion chamber, and an annular space between the shaft and the stator wall as a steam generator.

In the proposed turbine, the combustion products are directed from the combustion chamber into the channels of the jet gas turbine disk mounted on one end of the shaft, and the exhaust gases in it encompass a steam collector placed in the space between the stator and the turbine casing, where mesh is installed to completely absorb the heat of the exhaust gases. partitions. At the other end of the shaft, a jet steam turbine disk is fitted, equipped with channels to which steam comes from the steam collector.

The schematic drawing shows a longitudinal vertical section of a combined gas and steam turbine.

A disk B with channels of a reactive gas turbine is mounted on one end of the hollow shaft A, the cavity of which serves as a combustion chamber B, and an L disk // with channels of a reactive steam turbine at the other end. The combustible mixture is conducted under pressure into the combustion chamber B, where it ignites an electric spark. The resulting gases pass through the holes in the shaft body, enter the channels of the jet B of the reactive gas turbine and,

the output along the tangent of disk B and the impact of a special niche in the stator create a rotational motion of the turbine. Further, the exhaust gases are directed through the side windows D along the steam generator to the space between the stator and the casing I, where they cover the steam collector E. On the way, these gases pass a row of mesh partitions C designed to more fully absorb the heat of the exhaust gases of the turbine.

The space between the shaft L and the stator wall is used as a steam generator, which is filled with water i / K to the level of half the space between the upper part of the shaft and the upper stator. The heat radiated by the surface of the shaft during the combustion of the mixture inside it is completely absorbed by the water with its vaporization. Vaporization will be significantly accelerated when water is moved by a rotating shaft and by additional heating of the periphery of the boiler (stator wall) by the passing gases of the gas turbine. The steam generated in the boiler is directed to the steam collector E, located above the steam generator, and heated by the spent products, burning, after which, with sufficient pressure, the steam is directed through the steam line through the valve 3 to the shaft through the steam turbine H channel. . When exiting the turbine disk, steam, just like in a gas turbine, hitting the niche in the stator, rotates the disk H of the steam turbine. The exhaust steam through the side holes T is discharged into a special radiator. On the extension of the shaft A behind the disk H of the steam turbine, a group of gears / 7 is fixed to transmit the rotation of the shaft to the corresponding installations.
