Problems solved by technology

[0003] However, it has been determined that for gas turbine filter houses with asymmetrical geometries, the inlet air temperature distribution in the conduit downstream of the cooler coil is not uniform because the coils at different heights in the filter house The velocity of the inlet air flowing above is variable
The resulting uneven air temperature distribution can cause undesirable stress on compressor components

Embodiment Construction

[0034] figure 1 A typical asymmetrical gas turbine filter house 10 is shown including a filter section and cooler coil housing section 12 and outlet conduit sections 14, 16 to a compressor (not shown). A louvered inlet 18 directs outside or ambient air into the filter housing and it is understood that the inlet flow velocity profile varies with height within the upstanding filter and cooler coil housing section 12 . Note that the cooler coils, shown as dashed piping, are arranged substantially vertically (and either upstream or downstream of a filter element (not shown)), and the air velocities over and around the cooler coils and The temperature will therefore also vary according to altitude, since, for example, the air entering at the top of the filter housing, passing through the coil 20 (described below) and along the rear wall to the outlet duct 14 will have a lower velocity, And thus is exposed to the cooling coil for a longer period of time than air entering the filter...

Abstract

A chiller coil system for an asymmetric gas turbine filter house includes a plurality of chiller coil modules arranged in a substantially vertical array, each chiller coil module provided with a cooled fluid inlet pipe and a fluid outlet pipe . Each outlet pipe is connected to a common return pipe and at least some of the inlet pipes are connected to the common return pipe. A mixing control valve is provided for controlling an amount of cooling fluid in the common return pipe to be added to at least some of the inlet pipes.

Description

technical field [0001] The present application relates generally to gas turbines and, more particularly, to cooler coil assemblies in gas turbine inlet filter housings. Background technique [0002] A gas turbine engine typically includes a compressor for compressing incoming air, a combustor for mixing fuel and compressed air and igniting the fuel and air to form a high temperature gas flow, and a turbine section driven by the high temperature gas flow. It is generally accepted that reducing the temperature of the inlet air into the compressor leads to increased power output, and there are known methods for reducing the air inlet temperature of the engine in so-called power amplification systems. The power amplification system may include a cooler coil assembly located in the turbine inlet filter housing that reduces the temperature of the inlet airflow. Examples are described in, eg, US Patent No. 7,007,484 B2 and US Patent Publication No. 2005 / 0056023 A1. [0003] Howev...
