              燃料氣與空氣的流動方式   主要可以歸納為四種,燃料氣噴射到靜止的空氣中;燃料氣和空氣平行流動;燃料氣和空氣流動時相互之間有一定的夾角;燃料氣和空氣呈旋流運動。




              The flow of fuel gas and air can be divided into four main types, the fuel gas injected into the air; the fuel gas and the air flow in parallel; the fuel gas and the air flow between a certain angle; the fuel gas and air in a cyclone movement.


              燃料氣流直徑的影響:氣流直徑越大,完全混合的時間越長。為了加速混合,可以將大股氣流分成若干小股氣流。這就是一些大功率的燃燒器有多個燃料氣噴嘴的原因。



              The effects of the diameter of fuel air airflow larger diameter, the longer the complete mixing. In order to accelerate the mixing, the large strands of airflow can be divided into a number of small strands of air. This why some high-power burners have multiple fuel gas nozzles.


              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.




              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.
