Problems solved by technology

For example, compressing the tortuous flow path of the working fluid through the combustor may cause pressure loss and / or create areas of uneven flow through the combustor and / or nozzle
Each of these effects reduces the efficiency of the burner and increases the chances of flame holding in areas of low flow

Abstract

A system for conditioning flow through a plurality of nozzles arranged in a combustor includes a shield circumferentially surrounding at least a portion of the plurality of nozzles and a plurality of baffles disposed circumferentially around the shield. Each baffle is circumferentially disposed between adjacent nozzles.

Description

technical field [0001] The present invention generally relates to a system for regulating flow through a nozzle. In certain embodiments of the invention, a plurality of baffles may circumferentially surround a plurality of nozzles disposed in the combustor to improve distribution of compressed working fluid through the nozzles. Background technique [0002] Combustors are commonly used in industrial production and power generation operations to ignite fuel to produce combustion gases at high temperature and pressure. For example, gas turbines typically include one or more combustors to generate electricity or thrust. A typical gas turbine used to generate electricity consists of an axial compressor at the front, one or more combustors in the middle, and a turbine at the rear. After ambient air is supplied to the compressor, the rotating blades and stationary vanes in the compressor gradually transfer kinetic energy to the working fluid (air) to produce a compressed working...
