Problems solved by technology
[0007] In view of this, this disclosure proposes a plant layout for the application of multi-axis gas-steam combined cycle units, to at least solve the problem in the prior art that the height of the center line is too high and the investment cost of the main plant is too high, and too many auxiliary machine modules are set And the downward wiring of the bus duct of the generator leads to the problem of reducing the maintenance space, and the problem that the high and low position layout does not give full play to the advantages of large operation and maintenance

The invention relates to a multi-shaft gas-steam combined cycle unit. The multi-shaft gas-steam combined cycle unit comprises at least two sets of gas turbine units, each gas turbine unit comprises a gas turbine, a gas turbine generator and a gas inlet system, the gas turbines are coaxially connected with the gas turbine generators, and the gas inlet systems are located between the gas turbines and the gas turbine generators; the steam turbine sets comprise steam turbines and steam turbine generators, and the steam turbines and the steam turbine generators are coaxially connected; the gas turbine unit and the steam turbine unit are arranged side by side at the same center line height and are both arranged at the middle position, and the center line height is set between the center line height of the unit arranged at the high position and the center line height of the unit arranged at the low position.
Description
technical field [0001] The present disclosure relates to a multi-shaft gas-steam combined cycle unit. Specifically, the present disclosure relates to the arrangement of multi-shaft gas-steam combined cycle units in the main plant. Background technique [0002] Gas steam turbine combined cycle unit is a typical gas turbine unit application in the global thermal power market. It usually consists of waste heat recovery steam generator, gas turbine, generator and steam turbine. A typical plant layout structure is a multi-axis layout. For this arrangement, the shafts of the gas turbine and gas turbine generator are separated from the shafts of the steam turbine and steam turbine generator. There are many arrangements for the one-to-one multi-shaft gas-steam turbine combined cycle unit. [0003] In one of the plant layouts for multi-shaft gas-steam turbine combined cycle units, the height of the center line of the gas turbine unit and the steam turbine unit is relatively high,...
