摘要
Abstract
The influences of the oxygen-enriched combustion technology on temperature field, velocity field,reactant concentration and fuel consumption in cracking furnace were investigated through a 2D simulation to predict the oxygen-enriched combustion process using the commercial software Fluent. To describe the combustion process accurately,a CHEMKIN file including 16 species and 41 reactions was introduced into the Fluent software. The simulation also took into account the standardk-ɛ turbulence model,P-1 radiation model and turbulence-chemistry interaction. The results showed that,with increasing the oxygen concentration,the fuel burned more completely and the reaction heat increased. When the oxygen concentration(w) increased from 23.5% to 36.5%, in the furnace,the average temperature increased by 7.93% and the peak temperature increased by 4.33%;and at the effluent gas outlet of the furnace,the temperature increased by 3.56%,the CO concentration reduced by 54.5%,the CO2 concentration increased by 9.23% and the NOx concentration increased to 0.350 5%.关键词
