Type of calciner classification 1. The same line type decomposition furnace This type of precalciner sits directly above the kiln exhaust chamber. This type of furnace is actually an improvement and extension of the rising flue. It has the advantage of simple layout. The kiln gas directly enters the decomposition furnace through the kiln tail smoke chamber. Due to the large gas flow in the furnace and the low oxygen content, the decomposition furnace is required to have a large furnace capacity or a large gas and stagnation furnace.Vacuum high pressure gas nitriding process Stay long. This type of furnace has a simple, neat and compact layout, and the discharged gas directly enters the lowermost cyclone. Therefore, they can be arranged on the same platform, which is beneficial to reduce the height of the building. At the same time, the use of "gooseneck" pipe The structure increases the capacity of the furnace area, which is also conducive to the layout, and does not increase the height of the building.Comparison of Vacuum Sintering and Tunnel Furnace Sintering Technology 2. Offline calciner This type of calciner is self-contained. In this way, there are two rows of preheaters at the end of the kiln, one One row passes through the kiln gas, one row passes through the furnace gas, and the kiln row material flows to the lowest cyclone of the kiln row and then enters the decomposition furnace.Vacuum Heat Treatment of Cr12MoV Steel Ceramic Die After being heated and decomposed together with the furnace material in the furnace, it is separated by the lowest cyclone of the furnace and enters the kiln. same When the off-line kiln is generally equipped with two main exhaust fans, one is specially designed to suck the kiln gas, and the other is to suck the furnace gas. The working conditions of the two columns in production can be adjusted independently. In extra-large kilns, three columns of preheaters and two calciners are installed.
