The wall-type heating, non-traditional inner structural design, new technique of vapor activation, and automatic control system are used in this furnace. The adjustable range is wider and the controlled technique is elastic. It gives us good effects on reducing labor intensity, raising quality of products, and increasing activation rate. At the same time, the production command is directly sent by linking the control system of furnace with a computer. When the equipment has a breakdown, the system is able to give auto alarm during the running. The operator can quickly give a judgment on the breakdown by data analysis. The adaptability of raw material is wider. It is easy to change a new raw material. The result is obtained by setting parameters directly and then running 8-15 h after changing a new raw material.
