Classification of heating furnace:

According to the type of furnace type structure, there are box type furnace, vertical furnace and so on. According to the form of combustion, the bottom burning furnace and the side burning furnace. Classification according to the form of air supply: forced air supply furnace and natural supply wind.

燃料气与空气的混合物在燃烧焰面法线方向的速度分量大于该混合物的火焰传播速度，则火焰被推出火孔，开始离焰，直到火焰被吹跑造成火焰熄火——脱火。燃烧器发生脱火是不允许的。

The velocity component of the mixture of fuel gas and air in the normal direction of combustion flame is larger than that of the mixture, and the flame is pushed out of the fire hole and starts to le***e the flame until the flame is blown away, causing the flame to go out. It is not allowed to remove fire from the burner.

由若干个摆在一条线上的加热室所组成。加热室和加热室之间设间室，传送料坯的辊子设在间室内，坯单根（或双根）地通过各加热室和间室而被加热。每个加热室与相邻的间室构成一个“炉节”，所以又称节式炉。

It c***ists of several heating chambers on one line. There is a room between the heating chamber and the heating chamber. The rollers of the conveying blanks are arranged in the indoor room, and the single root (or two roots) of the billet is heated through the heating chambers and chambers. Each heating chamber and the rooms form a "furnace section", so it is also called a section furnace.
