ASSEMBLY COMPRISING A GAS TURBINE

摘要

An assembly includes a gas turbine and a heat exchanger for heating up a gas turbine process fluid by thermal energy. The gas turbine has a compressor, a combustor and a turbine downstream of the combustor, wherein the thermal energy is from the solar receiver. To improve efficiency and reduce power generation fluctuations, the assembly includes a first line to conduct the gas turbine process fluid downstream a compression by the compressor to the heat exchanger, and a second line to conduct the gas turbine process fluid from the heat exchanger to the combustor to generate hot combustion gas from the warmed up gas turbine process fluid burning fuel in the combustor.

1. An assembly (AS) comprising
a gas turbine (GT) and a heat exchanger (HE) for heating up a gas turbine process fluid (GTPF) by thermal energy, said gas turbine (GT) comprising a compressor (CO), a combustor (CB) and a turbine (TB) downstream said combustor (CB), wherein said assembly comprises a first line (L1) to conduct said gas turbine process fluid (GTPF) downstream a compression by said compressor (CO) to said heat exchanger (HE), and wherein said assembly (AS) comprises a second line (L2) to conduct said gas turbine process fluid (GTPF) from said heat exchanger (HE) to said combustor (CB) to generate hot combustion gas (HCG) from said warmed up gas turbine process fluid (GTPF) burning fuel (F) in said combustor (CB), wherein said combustor (CB) is defined by a first shell element (SE1) containing a main combustion zone (MCZ), wherein said combustor (CB) is at least partly surrounded by a second shell element (SE2) to provide an annular channel between said first shell element (SE1) and said second shell element (SE2) as a part of said first line (L1).
