Improved IBH system of H-25 gas turbine generator set

Abstract

The invention belongs to the technical field of gas turbine generator sets, and particularly relates to an improved IBH system of an H-25 gas turbine generator set. According to the improved IBH system, an original IBH system of the H-25 gas turbine generator set is improved, original bleed air is divided into two paths, one path is arranged in front of an air inlet filter element and used for preventing inlet air from being frozen under the low-temperature condition, the other path is used for arranging an original IBH bleed air pipe bundle in an air inlet channel behind an air inlet silencer, the air supply flow of an original IBH pipe bundle (a main air path) is greatly reduced, the air inlet anti-icing effect is guaranteed in the low-temperature environment, meanwhile, the total bleed air flow is kept to stabilize emission adjustment, the noise level of the whole system device during working is reduced, and the purpose of reducing the working noise of the system under the condition that it is guaranteed that the total bleed air amount of the gas turbine is unchanged is achieved.

Description

technical field [0001] The invention belongs to the technical field of gas turbine generating sets, and in particular relates to an improved H-25 gas turbine generating set IBH system. Background technique [0002] At present, due to the low temperature in winter in some project areas and strict emission requirements for gas turbine units, it is necessary to equip the H-25 gas turbine generator set with an IBH system. However, although the original IBH system can meet the requirements of anti-icing and emission regulation, which improves the emission of the unit in the range of low working conditions, but the operating noise is as high as 120 decibels, which cannot meet the general requirements of my country's industrial power generation field. Noise level of 85 decibels. Contents of the invention [0003] The purpose of the present invention is to provide an improved H-25 gas turbine that can not only maintain the total bleed air flow rate to stabilize the discharge regul...
