Abstract
In order to obtain a compact and serviceable gas turbine plant including a compressor and a turbine rotating about a common axis and further having at least one combustion chamber and an air preheater, the turbine and the compressor are spaced apart axially to provide a space for mounting the combustion chamber or for the gas discharge, respectively. The air-preheater is divided into at least two box-shaped units, each unit including at least two individually mountable exchanger elements. The power take-off with the pertaining reduction gear is located at the compressor end of the plant, leaving the turbine and heat exchanger easily accessible for servicing.
Claims9
A gas turbine power plant including:
- (a) a compressor part having a rotational axis;
- (b) a turbine part operating on the same rotational axis as the compressor part, but being axially-spaced therefrom and means forming a radial passageway for combustion gases between said compressor part and said turbine part, said turbine part being designed for axial flow and having an inward end adjacent to said radial passageway and an outward end remote therefrom;
- (c) at least one combustion chamber for supplying combustion gases to said turbine part;
- (d) airpreheating means for preheating combustion air between said compressor part and said at least one combustion chamber by means of combustion gases leaving said turbine part;
- (e) a common housing enclosing said compressor part, said turbine part and said air-preheating means;
- and (f) a power take-off from the power plant located at the compressor part end of the housing, said air-preheating means including at least two box-shaped units, located to opposite sides of said turbine part extending about from its inward end to its outward end and presenting an inward face towards said turbine part, and turning an outward face away therefrom, each of said units comprising at least two, heat exchange elements, arranged for parallel flow, distribution and collecting means at the axial ends of said elements as well as at the inward and outward faces thereof, said distribution and collecting means being defined by transverse end walls and inward axial walls, said walls being provided with fluid conductive sockets to individually and removably receive said elements, and each of said elements having a hollow stud and socket connector part at one axial end and an expandible bellows connector part at its opposite axial end, and further a stud and socket connector part at its inward face.
