              石油化學工業爐燃料氣與空氣混合物離開火孔速度一般都比較高,都超過其火焰傳播速度。但是燃燒器在結構上都有相應的措施保證不發生脫火現象,使火焰穩定燃燒。

              The mixture of fuel gas and air in the petrochemical furnace is generally higher than that of the flame, which is more than the flame propagation speed. But the structure of the burner has the corresponding measures to ensure that the flame is not degenerated and the flame can be burned steadily.


              按爐溫分布,爐膛沿長度方向分為預熱段、加熱段和均熱段。進料端爐溫較低為預熱段,其作用在于利用爐氣熱量,以提高爐子的熱效率。加熱段為主要供熱段,爐氣溫度較高,以利于實現快速加熱。

              According to the distribution of furnace temperature, the furnace is divided into preheating section, heating section and uniform heating section along the length direction.

              The lower temperature of the feed end is the preheating section, and its function is to increase the heat efficiency of the furnace by utilizing the heat of the furnace gas.

              The heating section is the main heating section, and the furnace gas temperature is relatively high, which is conducive to rapid heating.




              連續加熱爐通常使用氣體燃料、重油或粉煤,有的燒塊煤。為了有效地利用廢氣熱量,在煙道內安裝預熱空氣和煤氣的換熱器,或安裝余熱鍋爐。

              Continuous heating furnace usually use gas fuel, heavy oil or coal, and some coal burning. In order to effectively utilize exhaust heat, a preheat air and gas heat exchanger is installed in the flue, or a HRSG is installed.


              轉底式加熱爐

              爐身固定,爐底轉動,放置在爐底上的料坯隨爐底轉動由進料口移送到出料口。根據爐底的形狀,轉底式加熱爐可分為環形爐和盤形爐兩種,冶金廠軋鋼車間多用環形爐。



              Bottom reheating furnace

              The furnace body is fixed and the bottom of the furnace is rotated, and the billet placed on the bottom of the furnace is transferred to the discharge port from the feed inlet with the rotation of the furnace bottom. According to the shape of the furnace bottom, the rotary hearth furnace can be divided into two types: the annular furnace and the disc type furnace.
