Abstract

Provided is a turbogenerator set including a boiler, a steam turbine unit, a generator unit, a superheater, and a reheater in a body of the boiler, a header connection region corresponding to a steam inlet header and a steam outlet header for the superheater and the reheater on the body of the boiler, and pipes connecting the boiler to a high-pressure cylinder and to a medium-pressure cylinder, and transmitting a high-temperature and high-pressure steam. The steam turbine unit is disposed at an outer side of the boiler body adjacent to the header connection region, and an axis of the steam turbine unit vertically point to the boiler body, vertically arranged on a high level; that is, the steam turbine unit is vertically arranged on a high level.

Claims

1. A turbogenerator set, comprising:

a boiler, comprising a boiler body and at least one primary superheater and at least one primary reheater disposed within the boiler body;

wherein each of the at least one primary superheater and each of the at least one primary reheater individually comprises a steam inlet header and a steam outlet header, and the boiler body is provided with a header connection region corresponding to the steam inlet header and the steam outlet header;

a steam turbine unit, comprising at least one high-pressure steam turbine and at least one medium-pressure steam turbine;

a generator unit, comprising at least one generator connected to the steam turbine unit; and

a steam pipe system, comprising at least pipes connecting the boiler to the at least one medium-pressure steam turbine and connecting the boiler to the at least one high-pressure steam turbine and configured to transport a high-temperature and high-pressure steam;

wherein the steam turbine unit and the generator unit are arranged at an outer side of the boiler body adjacent to the header connection region, and the steam turbine unit and the generator unit are arranged in a high-level vertical manner, wherein longitudinal axes of the steam turbine unit and the generator unit vertically point to an axis of a left-right oriented wall of the boiler body.

2. The turbogenerator set of claim 1, wherein the turbogenerator set is common-shaft arranged, and wherein the at least one high-pressure steam turbine, the at least one medium-pressure steam turbine, and the at least one generator are arranged in a same shaft system.

3. The turbogenerator set of claim 1, wherein the turbogenerator set is spilt-shaft arranged, and the generator unit comprises a first generator and a second generator, wherein the at least one high-pressure steam turbine and the first generator constitute a first shaft system;
