Investigation of the Operation of a High-Loaded Three-Register Combustion Chamber for a Gas Turbine,
FOREIGN TECHNOLOGY DIV WRIGHT-PATTERSON AFB OH
Studies of an experimental nature were conducted on a test combustion chamber consisting of a rigid housing, flame tube, fuel injection nozzle, and mixing unit, with three concentrically arranged registers located in the front part of the chamber. The studies aimed at 1 implementation of optimum air distribution 2 determination of the chamber flow resistance 3 determination of the combustion efficiency of the chamber as a function of operating mode, excess-air coefficient, and pressure 4 investigation of the temperature fields of the gas flow within the chamber 5 determination of the velocity fields of the gas flow within the chamber 6 determination of the temperature of the structural components of the chamber and 7 verification of the stability of combustion with the chamber operated under different loads. It is concluded that the test results pointed to adequate service life and acceptable economy in the type of combustion chamber tested efficiency factors of from 95 to 98 were achieved, with a maximum resistance factor equal to, or greater than, 5.
