Abstract

The invention discloses process equipment for improving the power capability of a steam turbine of a waste heat power generator set. The process equipment comprises a coal gas after-combustion device; one end of the coal gas after-combustion device is connected with a coal gas source pipeline, and the other end of the coal gas after-combustion device is respectively connected with a combustion-supporting blower and an induced draft fan connected with a chimney; the coal gas after-combustion device is respectively connected with a main steam steam-water separator, a main steam heat accumulator I and a main steam heat accumulator II, the main steam steam-water separator is also respectively connected with a steam-steam heat exchanger and a supplementary steam heat accumulator, the steam-steam heat exchanger is connected with a supplementary steam steam-water separator, and the supplementary steam steam-water separator is also connected with a supplementary steam source pipeline; each of the main steam heat accumulator I and the main steam heat accumulator II is connected with a main steam source pipeline; and each of the main steam heat accumulator I and the main steam heat accumulator II is connected with a water supplementing pump by a water supplementing pipeline. By using the process equipment, the problems that the steam consumption rate of the steam turbine of the current waste heat power generator set is relatively high, the generating capacity cannot reach a design value and the change of the power generation load is greater are overcome.

Description

technical field [0001] The invention belongs to the technical field of waste heat power generation, and relates to a process equipment for improving the working ability of a steam turbine of a waste heat generating set. Background technique [0002] The waste heat generator set is generally composed of a steam turbine and a generator. The recovered industrial waste heat generates steam, which drives the steam turbine to do work, thereby driving the generator to generate electricity. Due to the periodic peak and valley changes in the production of industrial enterprises, the quality and flow of steam produced by waste heat recovery are greatly affected by the production status. The working capacity of the steam turbine fluctuates with the change of the production cycle, resulting in unstable power generation load of the generator, and the power generation cannot reach the design value for a long time. At the same time, the steam quality is low, resulting in a high steam consu...
