高爐熱平衡
英文
blast furnace heat balance-
The temperature distribution on the high temperature side of an electric tunnel furnace is analysed and simulated on the basis of the principle of thermal radiation by the way of thb ( thermal heat balance ). the heated silicon carbon sticks are decomposed into innumerable tiny heating faces, which exchange the heat with the heated materials. a numerical model based on the radiation intensity law is constructed to calculate the energy absorbed by the heated materials and simulated by a computer. the results showed that the even distribution of temperature can be obtained by optimizing the arrangement of the silicon carbon sticks according to the calculation results to make the structure design more reasonable. these calculation results have been used in the practical designs and the expected objectives achieved
利用熱輻射原理，採用熱平衡法對電熱隧道窯的高溫恆溫區溫場進行了分析和模擬.計算中將發熱棒分解為無數微元發熱面與燒結體進行熱交換，依據輻射強度定律，建立了燒結體接收能量的數學模型，並用計算機進行了模擬計算.結果表明，依據模擬結果來優化硅碳棒的排布，可使結構設計更加合理，進而可以獲得分佈均勻的恆溫區溫場.計算結果已在窯爐設計中應用，實踐效果良好There is a chemical reserve zone in the stack. in this zone the fe is present as feo, and the gas component is close to the balance composition of fe0. 947o / fe. so there is a part of longitudinal section, in which : l ) gas keeps its component, as ascending. 2 ) the composition of the gas is close to the equilibrium composition of the fe0 947o + co - " 0. 947fe + co2 under the temperature of the thermal reserve zone of about 1200 + 100k
根據冶煉理論，高爐在爐身一定高度上有一個「化學貯備區」 ，在該區，含鐵物料實際上都是浮氏體，並且煤氣成分接近fe _ （ 0 . 947 ） o fe平衡時的成分，這樣，高爐內存在高爐熱控制模型開發一個縱向區域，在該區內：二）煤氣上升時，成分不變。3. on boiler retrofit, the calculation of fuel burning, the heat calculation of boiler inside structure and convection section, and the design of structure parameter of feed water heat exchanger are made. the flue gas channels " resistance calculation and the boiler strength verifying are also carried out. replacement of water cooling wall improves heat exchanging and decreases loss of heat radiant
