  1. After thermodynamic calculation on several operation conditions of the furnace, cold - state flow and resistance mensuration, the combustion of the tubular - furnace hearth was changed into swirl and addition of radiate cylinder and oxygen content detection minish 1. 25 surplus air to less than 1. 15, improving the combustion condition and convection and radiate heat transfer efficacy, resuling in reducing the waste - gas temperature 45, decreasing exhaust gas loss, and saving fuel by 6 %

    摘要通過對加熱爐幾種工況進行熱力計算、冷態試驗的流場分佈及阻力測定和熱態試驗的爐膛溫度場分佈及壁溫度等參數的測定,確定將式加熱爐爐膛內直流燃燒改為旋流場燃燒和增加輻射筒,增設煙含氧量分析,可以將燃燒的過剩空系數從1 . 35減小到1 . 15以,極好地改善爐膛內的燃燒狀況和對流輻射傳熱效果,從而低排煙溫度45 ,減少加熱爐排煙損失,節約了量6 %以上。
