Embodiment Construction

[0030] Gas turbines have a wide variety of applications such as power generation, gas compression, and many other mechanical transmission applications. The various aspects presented herein can be used with any type of gas turbine; however, for convenience, the description will be made here in terms of a gas turbine used in a power plant. Those of ordinary skill in the art will readily understand the adjustments required for other types of appropriate turbines.

[0031] Figure 1 shows a representative configuration of a gas turbine intake section. Arrows show the direction of airflow. Ambient air enters duct 101 through weather louver 102 , screen 103 and air filter 104 to the inlet of gas turbine 10 . Gas turbine 10 includes a rotor with blades and a casing 11 . At the front end of the shaft, compressor blades 12 compress the air to a high pressure, eg typically 10 to 30 times the normal air pressure. The compressed air is delivered to the combustion chamber 13 . Fuel (no...

Abstract

A method and system augments shaft output of gas turbine engines that can be used in multiple modes of operation. The system comprises a washing unit capable of injecting atomized water into the gas turbine engine, thereby obtaining a release of fouling material from the at least one compressor blade; and at least one water injection unit capable of injecting atomized water into the air stream of the gas turbine engine's inlet duct or at the gas turbine, under the control of a computational fluid dynamic model, in order to increase a mass flow of said air flow, wherein the power output from said gas turbine engine can be augmented.

Description

technical field [0001] The present invention relates generally to the field of gas turbines. In particular, the present invention relates to systems and methods for high pressure compressor cleaning in combination with water delivery equipment for increasing the mass flow of a gas turbine, thereby increasing its power output, thereby controlling the system. Background technique [0002] Producing power requires gas turbines to consume large volumes of air. Gas turbines depend heavily on the ambient air conditions for their performance. Ambient air conditions such as temperature, air pressure, and moisture content affect the ability of the gas turbine's compressor to compress the air, thereby affecting its performance. In other words, gas turbine power is a function of the total mass flow achieved by compression, combined fuel and expansion to drive the turbine section. Mass flow is directly proportional to engine power output. Gas turbines are fixed volume machines (ie,...
