THE USE OF COMPUTERS TO CALCULATE THE COMBUSTION CHAMBERS OF GAS TURBINES OPERATING ON NATURAL GAS,

Abstract

The introduction of computer technology makes it possible to calculate the combustion processes and heat transfer in gas turbine combustion chambers. In such a problem, the mathematical model includes all known physico-chemical interactions of the parameters of the process and the minimum number of experimental coefficients. Experimental studies in such cases are limited to the determination of these coefficients and to the verification of the correctness of the mathematical model. The accumulated experimental information and its analysis are sufficient to outline a method for carrying out calculations of telescopic single, swirl-cup combustion chambers operating on natural gas. In this calculation method, it is assumed that the flame and wall temperatures and the heat fluxes along the length are constant and equal to the means of their corresponding values. This assumption varies little from the actual process which takes place in a combustion chamber. The method is based on four formulas: (1) the heat liberation formula; (2) the heat removal (balance to the combustion chamber); (3) the heat transfer formula; and (4) the heat balance at the combustion chamber wall.
