電廠煙風道異型件阻力系數的數值計算方法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
對鍋爐本體進行了燃料燃燒計算、爐膛結構熱力計算、對流受熱面結構熱力計算、鍋爐給水加熱器結構參數設計、煙道阻力計算及鍋爐元件強度校核等;改進了水冷壁布置使換熱效果更好,減少輻射換熱損失;改進對流段結構,更充分的利用爐膛出口煙氣余熱,提高熱效率;並且進行了煙氣阻力計算、熱效率計算和能量平衡測試,對改進后的稠油燃料和改進前進行了對比,燃燒狀況和熱效率有明顯改善。In order to solve the problems effectively, under the auspices of 863 plan in china, the synthesis diagnosis has been carried by means of measuring and numerical imitating the combustion chamber of refining column, and some conclusions is such as : ( 1 ) through measuring the temperature and combustion in the burning chamber of the refining column, the result shows the temperature difference on the same level is more than that in height direction, and there is a few of co in bottom of burning chamber. ( 2 ) in order to ensure normal work of flue system in lead column in the course of zinc refining, theoretic calculation and measure about the flow resistance of exhaust gas are carried through. the results of study reveal that drawing out force of chimney is inadequate, which is mainly caused by illogicality of flue construction
在研究過程中,採取了現場實測和數值模擬手段對韶關冶煉廠鋅精餾鉛塔燃燒室及排煙系統進行了綜合診斷,具體結果包括如下: ( 1 )完成鋅精餾鉛塔燃燒室內溫度測試以及燃燒狀況的測試,結果發現:鉛塔燃燒室內水平方向的煙氣溫度並非均勻,而且其溫差比上下方向的溫差更大,以及鉛塔燃燒室尾部存在co未燃燼問題; ( 2 )為了保證鉛塔煙氣系統的正常工作,對煙道系統的阻力進行了理論計算及測試分析,結果發現:鋅精餾鉛塔煙氣系統中煙囪抽力不夠,這主要是煙道結構不合理所造成的。Secondly, the paper simplified the calculating model of fume in the high tunnel. took the fume restriction into account, the paper provided some equations to calculate the longitudinal fire ventilation. finally, the paper calculated three examples : the zhongliangshan tunnel and the left route of the yanmenguan tunnel
最後,本文將公路隧道火災的通風模型進行簡化,考慮火災煙流阻力(節流阻力,摩擦阻力,火風壓)的影響,提出了縱向式火災通風計算的方程式,並對中梁山隧道的左右線、雁門關隧道的右線進行了實例計算。分享友人
