高爐熱風(fēng)爐可變周期運(yùn)行策略的研究和實(shí)現(xiàn)

提出了一種基于送風(fēng)溫度預(yù)測(cè)實(shí)現(xiàn)的熱風(fēng)爐系統(tǒng)，該系統(tǒng)為可變周期運(yùn)行和控制。它以整個(gè)熱風(fēng)爐系統(tǒng)的最低送風(fēng)溫度作為總的控制指標(biāo)，采用基于實(shí)例的方法推理預(yù)測(cè)送風(fēng)結(jié)束時(shí)間，并根據(jù)預(yù)測(cè)結(jié)果動(dòng)態(tài)地調(diào)節(jié)后續(xù)送風(fēng)熱風(fēng)爐的燃燒終點(diǎn)，從而使各個(gè)熱風(fēng)爐在燃燒階段所積蓄的熱量得到充分的釋放，以達(dá)到降低煤氣消耗和減少熱風(fēng)溫度波動(dòng)的雙重目的。

Abstract：A hot - blast stove system implemented based on predicted temperature of forced air is proposed. The system is operated and controlled under variable cycle. The whole system is operated with the minimum temperature of forced air as the goal，and by using inference for predicted end time of forced air based on practical example，and dynamically regulating combustion end point for feeding air afterwards. Thus the heat storage in each hot - blast stove during combustion period can be fully released，by which the gas consumption is reduced and the temperature fluctuation of hot air is decreased.
