AERODYNAMICS AND MIXTURE FORMATION IN BURNERS WITH A MULTI-ROW JET FUEL SUPPLY SYSTEM |
| description |
The purpose of the work is to establish the laws of isothermal flow and mixture formation of fuel and oxidizer in a new modification of microjet burners equipped with a three-row fuel jet system and oriented to operation at various values of the excess air coefficient. The proposed burners are designed to provide the ability to control the composition of the fuel mixture in the flame stabilization zone and, in general, high efficiency of fuel combustion under the conditions under consideration. As part of the work, the following tasks were to be solved: to establish the main characteristics of the flow and mixture formation in the these burners; to identify the effects of various factors on the structure of the flow and mixture formation in these burners; to determine the rational design parameters of the fuel gas supply system, which realize favorable conditions for the mixture formation of fuel and oxidizer in the flame stabilization zone of the proposed burners. Computer simulation using Fluent code was used as a research method.
The main features of aerodynamics and mixture formation of fuel and oxidizer in the considered burner devices are revealed. The dependences of the characteristics of the processes under study on a number of design and operating parameters have been established. In particular, a comparative analysis of the patterns of flow and mixture formation during the operation of burner devices was performed for various values of the excess air coefficient corresponding to the supply of fuel gas to various fuel supply sections. Data have been obtained to determine the values of the geometric parameters of the fuel supply system, under which the necessary conditions for mixture formation in the flame stabilization zone are realized.1548 |
