从传热、传质、动量传输和化学反应等基础理论出发,运用FLUENT建立加热炉燃烧模型,对炉膛内的温度、速度、浓度进行分析,考察空气预热温度和过剩空气系数对燃烧状况、炉内温度均匀性及污染物排放特性的影响;综合分析加热炉适宜操作范围及最优操作边界点,以此来确定加热炉优化燃烧卡边条件,改善加热炉燃烧状况,对节能减排都具有积极作用。
Based on the basic theories of heat transfer, mass transfer, momentum transfer and chemical reaction, the combustion model of the heating furnace was established by using FLUENT, the temperature, velocity and concentration in the furnace were analyzed. The influence of air preheating temperature and excess air coefficient on combustion, Furnace temperature uniformity and pollutant discharge characteristics; comprehensive analysis of the heating furnace suitable operating range and the optimal operating boundary point, in order to determine the heating furnace to optimize the combustion card edge conditions, improve the combustion furnace heating conditions, energy saving Has a positive effect.
