Benefits of technology

This patent describes an air supply and conditioning system for a turbine system that includes an atomizing air system, an air processing unit, and a filter housing. The system can cool and condition the air supply from a gas turbine component to a desired temperature and pressure before supplying it to a filter housing for further filtration. The technical effect is to provide a more efficient and effective air supply system for turbine plants, which can improve operational performance and reduce maintenance costs.

Problems solved by technology

The heat exchanger is rather costly from both a part and installation cost perspective, as well as a drain on an auxiliary power system for operation of the heat exchanger.

Embodiment Construction

[0013]Referring to FIG. 1, a turbine system is schematically illustrated with reference numeral 10. The turbine system 10 includes a compressor 12, a combustor 14, a turbine 16, a shaft 18 and a fuel nozzle 20. The compressor 12 and the turbine 16 are coupled by the shaft 18. The shaft 18 may be a single shaft or a plurality of shaft segments coupled together to form the shaft 18. Additionally, an inlet filter assembly 22 ingests an airstream 24 that is filtered and routed to the compressor 12. The combustor 14 uses a combustible liquid and / or gas fuel, such as natural gas or a hydrogen rich synthetic gas, to run the gas turbine system 10.

[0014]The inlet filter assembly 22 includes an entry portion 30 for the airstream 24, where the entry portion 30 typically comprises one or more weather hoods or louvers. The entry portion 30 provides a path for the airstream 24 to enter an inlet filter compartment 32 from ambient surroundings. An inlet duct 34 is configured to contain and route th...

Abstract

An air supply and conditioning system for a turbine system includes an atomizing air system comprising at least one conditioning component configured to receive a compressor discharge air supply at an inlet at a first temperature and a first pressure, wherein the at least one conditioning component conditions the compressor discharge air supply to a second temperature and a second pressure at an outlet. Also included is an air processing unit configured to receive the compressor discharge air supply from the outlet of the atomizing air system, wherein the air processing unit further conditions the compressor discharge air supply to a third temperature and a third pressure. Further included is a filter housing having at least one filter for filtering a main inlet airstream, wherein the compressor discharge air supply is provided from the air processing unit to the at least one filter.

Description

BACKGROUND OF THE INVENTION[0001]The subject matter disclosed herein relates to turbine systems, and more particularly to an air supply and conditioning system for turbine systems, as well as a method of supplying air within such turbine systems.[0002]Turbine systems often include an air processing unit (APU) that provides an air supply for pulsing self-cleaning filters within a filter housing and also that provides an air supply to one or more valves as instrument air. The air supplied to the APU typically is extracted directly from a compressor discharge casing, where the air is relatively hot and requires substantial cooling and lowering of pressure prior to injection into the filter housing. Various devices within the APU are present to perform such cooling and pressure lowering of the air supply, with one such device including a heat exchanger. The heat exchanger is rather costly from both a part and installation cost perspective, as well as a drain on an auxiliary power system...
