摘 要: 通過對環(huán)式陽極焙燒爐的熱工過程進行系統(tǒng)理論分析， 建立了焙燒爐熱工過程的數(shù)學(xué)模型。 對焙燒爐進行模擬計算的結(jié)果表明： 焙燒過程中陽極內(nèi)部溫差最大的地方主要集中在爐頂，應(yīng)采取相應(yīng)的措施減少爐頂?shù)臒釗p失以保持陽極焙燒溫度的均勻性； 同時， 不同的火焰循環(huán)時間和空氣滲漏對焙燒的能耗影響較大， 降低火焰循環(huán)時間將導(dǎo)致能耗增加， 而降低空氣滲漏量則可極大地降低能耗。

Abstract:Through the systematic analysis of ring anode baking process, a mathematical model was developed. Several simulation runs were then made. The simulated results indicate that the maximal temperature gradient is focus on the top of anodes. In order to preserve the uniformity and stability of the baking temperature in anodes, some relevant measures to reduce this heat loss should be taken. It is also found that the fuel consumption increases with the decrease of firing cycle time, and cutting down the air infiltration will be helpful for saving fuel.
Key words: baking furnace; heat transfer; numerical simulation
