{Tube furnace heating is due to the use of gas and air dispersed incineration to form a high temperature flame, so that the furnace and partition wall heating, and heating the gas itself to a high temperature, on the other hand, the influence of gas activity moistening and play the effect of convective heat transfer. In the radiation chamber, the furnace tube is mainly subjected to high heat radiation, and the tar in the tube can be heated to 400 C, so it is suitable for two-stage heating. There are 70 tubes in the convection chamber, which are mainly heat conduction due to the moisture of gas. The tar in the tubes can only be heated to 130 C, so it is suitable for two-stage heating and dehydration.Vacuum furnace manufacturer
The coking treatment of tubular furnace is the most commonly used method, and the heating of tubular furnace is the air-steam coking method in the simplest way. It is found that after coking of furnace tube (the pressure of the second stage pump increases at the inlet of furnace when the processing capacity and moisture content and properties of tar remain unchanged), it is possible that coking of furnace tube can be achieved by air-steam. The precondition of air-steam coking method is that the furnace tube is not blocked, and the coking treatment method is to pass air and steam into the inlet of the furnace in proportion, and heat the furnace with gas to a certain temperature. The coke and air reaction (incineration) in the furnace tube are thoroughly removed.Vacuum furnace manufacturer
