600～1400毫米。高壓油嘴是用蒸汽或壓縮空氣作霧化介質，壓力一般高達(3～12)×105帕，由于霧化介質壓力高，噴出速度能達到或超過聲速，所以高壓油嘴的霧化能力比低壓油嘴強，霧化粒徑可達20～30微米，但需要附加一條輸送助燃空氣用的通道和相應的氣流導向設施。根據(jù)不同的用途設計相適應的工業(yè)爐。重慶德國進口工業(yè)爐供應</p><div

style="text-indent:25px">由工業(yè)爐（窯）的定義、分類及結構章節(jié)可知，鍋爐本質上也屬于工業(yè)爐窯，從結構上講，其即有“鍋”的特殊結構，也有“爐”的通用結構，因此，鍋爐安全技術對于大多數(shù)工業(yè)爐來講，都有一定的通用（爐結構部分）借鑒作用。另外，許多其它類型的工業(yè)爐，如軋鋼加熱爐，也同時具有“鍋”和“爐”兩個部分的結構，只不過鍋爐產蒸汽是其主要功能，而加熱爐產蒸是其附屬功能，（一個是專業(yè)產汽，一個是業(yè)余產汽，所以加熱爐也不屬于特種設備），加熱爐的“鍋”結構部分通常稱為汽化冷卻系統(tǒng)，其汽包的安全運行規(guī)則原理與鍋爐的鍋筒部分幾乎完全同理，故鍋爐的安全技術對此類型爐窯則具有完全相似的借鑒作用。工業(yè)爐具備要求：升溫速度快，單位面積產量高。</p><div

style="text-indent:25px">工業(yè)爐的結構、加熱工藝、溫度控制和爐內氣氛等，都會直接影響加工后的產品質量。在鍛造加熱爐內，提高金屬的加熱溫度，可以降低變形阻力，但溫度過高會引起晶粒長大、氧化或過燒，嚴重影響工件質量。在熱處理過程中，如果把鋼加熱到臨界溫度以上的某一點，然后突然冷卻，就能提高鋼的硬度和強度；如果加熱到臨界溫度以下的某一點后緩慢冷卻，則又能使鋼的硬度降低而使韌性提高。為了獲得尺寸精確和表面光潔的工件，或者為了減少金屬氧化以達到保護模具、減少加工余量等目的，可以采用各種少無氧化加熱爐。在敞焰的少無氧化加熱爐內，利用燃料的不完全燃燒產生還原性氣體，在其中加熱工件可使氧化燒損率降低到0.3%以下。重慶德國進口工業(yè)爐供應</p></p><br
