The reform scheme of no . 1 boiler in fengtai company is confirmed on the basis of cold / hot tests , theoretical discussions and calculations . in the process of field retrofit , it is indicated in the operation of the improved furnace that without the change of furnace structure , the transform of the burner angle has shrunk the tangential diameter and prevented flames burning on furnace walls , and the burning state of furnace has been bettered , simultaneously , lowering the slagging wi in furnace , thus laying sol id foundation for the safe and economic operation of generating units . wuyanrong ( power plant thermal power engineering ) directed by prof 本論文通過(guò)冷、熱態(tài)試驗(yàn),經(jīng)過(guò)論證和計(jì)算,確定了豐泰公司~ # 1爐燃燒器的改造方案,并進(jìn)行了現(xiàn)場(chǎng)改造,改造后實(shí)際運(yùn)行狀況表明:在無(wú)法改變爐膛結(jié)構(gòu)的情況下,改變?nèi)紵鹘嵌?,縮小切圓直徑,使火焰不貼壁,改善了爐內(nèi)燃燒工況,同時(shí)降低了鍋爐結(jié)渣的程度,為機(jī)組的安全經(jīng)濟(jì)運(yùn)行奠定了必要的技術(shù)基礎(chǔ)。
