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管壁溫度等參數的測定,確定將管式加熱爐爐膛內直流燃燒改為旋流場燃燒和增加輻射筒,增設煙氣含氧量分析,可以將燃燒的過剩空氣系數從1 . 35減小到1 . 15以下,極好地改善爐膛內的燃燒狀況和對流輻射傳熱效果,從而降低排煙溫度45 ,減少加熱爐排煙損失,節約了煤氣量6 %以上。Heat pipe air pre - heater is adopted to recover gas heat to heat up cold air for burning, reducing flue gas temperature and increasing heat efficiency of injecting steam boiler
採用熱管式空氣預熱器,利用排煙熱量加熱冷空氣,降低了煙氣溫度,減少排煙熱損失,提高注汽爐熱效率。There are 3 parts of heat loss for gas boiler, including heat emission loss, uncompleted burning loss and fume hot loss, uncompleted burning loss decreases following the increase of excess air coefficient, while fume hot loss increases. it is obvious that there exit an optimum coefficient of excess air which make boiler own highest efficiency which is the purpose of burning control
不完全燃燒熱損失隨過量空氣系數的增大而減小,而排煙熱損失隨過量空氣系數的增大而增大,不難看出,存在一最佳的過量空氣系數使得兩者之和最小,即使得鍋爐的熱效率最高,燃燒控制的目的即在於此。Via the analysis of heat balance computation model and the computation of online heat balance for industrial coal boiler, this dissertation researched overall input heat, efficient utilized quantity of heat, heat losing of discharge flue gas, heat losing of chemistry and mechanism incomplete combustion, heat losing of dispelling heat of boiler, heat efficiency, air superfluous coefficient, wind speed, wind quantity, computation of primary air circle cutting and whose influence on boiler combustion efficiency
