Abstract

The invention provides a main pipe type micro gas turbine set with two air compressors, which relates to a gas turbine set for generating electricity. The micro gas turbine set solves the problem that the prior micro gas turbine set cannot keep higher running efficiency in a wider load change range. An output shaft of a first motor (8) is connected with an output shaft of a first air compressor (2) through a first lamination coupling (6), an output shaft of a second motor (9) is connected with an output shaft of a second air compressor (3) through a second lamination coupling (7), outputs of the first air compressor (2) and the second air compressor (3) are connected with an inlet of a main pipe (1), an output of the main pipe (1) is connected with an inlet of a combustion chamber (4), an output of the combustion chamber (4) is connected with an inlet of a turbine (5), and an output shaft of the turbine (5) is connected with one end of a third lamination coupling (10). The main pipe type micro gas turbine set achieves the aim of keeping the higher running efficiency in a wider load change range, improves the running performance of the air compressors, and improves the overall economical efficiency of the gas turbine set.

Description

technical field [0001] The invention relates to a gas turbine set for power generation, in particular to a micro gas turbine set for distributed energy applications. Background technique [0002] In the existing micro gas turbine unit, the compressor and the turbine are coaxial (such as image 3 shown), the driving force of the compressor is provided by the turbine. The compressor, combustor, and turbine are used as a whole as a power source, and the shaft power is transmitted to the generator through the coupling, and finally converted into electrical energy to supply power to users. For distributed energy applications, user load characteristics change drastically and there is a huge peak-to-valley difference, which requires its power equipment to provide stable load output within a wide power range. Using the existing micro gas turbine unit as the power equipment of the distributed energy system will face a difficult situation: in order to meet the load needs of users, th...
