Numerical Simulation about Fuel Injection Source Location Impacting on Turbulent Combustion Process

Abstract

Abstract: Fuel injection source location has very important influence on combustion process. It determines the location of the furnace flame. The three dimensional model of the furnace was established by the numerical simulation method. Under different conditions, the fuel injection source location on the temperature field within the furnace, the pollutant concentration field, and the flow field distribution inside the furnace combustion process were investigated. The results were compared and analyzed. After analysis, the results show that the fuel injection source location from 1.1 ~ 1.5 meter process of change, the average temperature within the furnace continue to rise, the concentration of pollutants Nitric oxide increased first and reduced after. This will help to explore the fuel injection source location effecting on combustion process, which makes a further understanding on optimization and heat transfer inside the furnace, and this has significance for improved combustion model.

Key words: numerical simulation, combustion, fuel injection source location, temperature field, pollutant concentration field
