1、平頂山工業(yè)職業(yè)技術(shù)學(xué)院畢業(yè)設(shè)計(jì)說(shuō)明書(shū)（論文）焦?fàn)t熱平衡系統(tǒng)的設(shè)計(jì)摘 要焦?fàn)t是煉制焦炭的窯爐，是煉焦主要的熱工設(shè)備，焦?fàn)t主要生產(chǎn)的是冶金焦。焦?fàn)t采用煤氣進(jìn)行加熱，消耗煤氣量約占煉焦廠總能消耗的70%左右。為了節(jié)約能源和降低能耗，對(duì)焦?fàn)t進(jìn)行熱平衡測(cè)試有著重要的意義。焦?fàn)t熱平衡又稱(chēng)能平衡或能量平衡，它僅分析熱量在數(shù)量上的平衡。熱平衡的方法又俗稱(chēng)“熱診斷”。焦?fàn)t熱平衡是根據(jù)能量守恒定律對(duì)進(jìn)入焦?fàn)t的物料和產(chǎn)出的煉焦產(chǎn)品進(jìn)行的熱量衡算。焦?fàn)t熱平衡足在焦?fàn)t物料平衡和燃燒計(jì)算的基礎(chǔ)上進(jìn)行的。物料平衡是對(duì)煉焦過(guò)程中焦?fàn)t系統(tǒng)的進(jìn)料量和出料量進(jìn)行的衡算。煤料經(jīng)焦?fàn)t炭化室內(nèi)結(jié)焦過(guò)程得到焦炭、焦?fàn)t煤氣和化學(xué)產(chǎn)品等物料
2、，焦?fàn)t物料平衡就是對(duì)這些物料的量進(jìn)行測(cè)定，列出進(jìn)出料淸單，根據(jù)物質(zhì)不滅定律進(jìn)行衡算，求得煉焦產(chǎn)品的產(chǎn)率和損失率，為焦?fàn)t熱平衡計(jì)算提供依據(jù)。通過(guò)熱平衡計(jì)算，可具體了解焦?fàn)t熱量的轉(zhuǎn)移、分配、利用和損失情況，獲得焦?fàn)t熱功效率和煉焦耗熱量數(shù)據(jù)，明確節(jié)能途徑和方向，為評(píng)定焦?fàn)t爐型和焦?fàn)t熱工狀況提供依據(jù)。關(guān)鍵詞：焦?fàn)t，焦?fàn)t熱平衡，物料衡算，焦?fàn)t熱工效率，煉焦耗熱量平頂山工業(yè)職業(yè)技術(shù)學(xué)院畢業(yè)設(shè)計(jì)說(shuō)明書(shū)（論文）AbstractCokeovenfurnacerefiningcoke,cokethermalequipmentisthemain,mainlytheproductionofmetallurgical
