(1)標(biāo)準(zhǔn)荷載下，四川回火臺(tái)車爐設(shè)備，模擬條件的爐身各開孔率均使?fàn)t頂封罩孔洞周邊處于彈性狀態(tài)。

(2)重復(fù)利用熱量，也就是，對(duì)溫度高的熱較作多級(jí)利用，例如，多效蒸發(fā)。 (3)將化工裝置中的余汽和廢熱用作余壓發(fā)電。 (4)大型合成氨和乙烯裝置用高溫廢熱鍋爐產(chǎn)生蒸汽驅(qū)動(dòng)工業(yè)汽輪機(jī)發(fā)電。 (5)大型合成氮裝里還可在空氣-煙氣側(cè)裝設(shè)燃?xì)廨啓C(jī)裝置，以其排氣作為燃燒所需部分空氣鼓入一段轉(zhuǎn)化爐燃燒器，但因考慮到燃?xì)廨啓C(jī)檢修時(shí)仍希望一段轉(zhuǎn)化爐繼續(xù)運(yùn)行。所以仍有鼓風(fēng)機(jī)鼓送常溫空氣作為全部或補(bǔ)充部分燃燒需要。 (6)煤轉(zhuǎn)化裝置研制中巳有考慮將氣化爐接入燃?xì)廨啓C(jī)裝置的高壓回路。即由壓氣機(jī)供應(yīng)空氣而把制成高溫煤氣導(dǎo)入燃?xì)廨啓C(jī)發(fā)電。 (7)更巧妙的節(jié)能技術(shù)是將廢熱供給本流程另一些工藝使用。例如將臺(tái)車爐合成氨裝置的一段轉(zhuǎn)化護(hù)高溫氣體焓供給一段轉(zhuǎn)化爐使用。這樣，再加上提高熱空氣溫度、有望取消一段轉(zhuǎn)化爐所需要的燃料。河北廂式臺(tái)車爐公司爐口采用重質(zhì)防撞磚、臺(tái)車面層重質(zhì)高鋁防壓磚。</p><div
