Principle of
muffle furnace
The muffle furnace is a device for gas separation under high temperature and high pressure, and its principle is based on the muffle effect. The muffle effect refers to the collision caused by the thermal motion of some gas molecules at high temperature and high pressure, which causes them to tend to move towards the fluid region moving at high speed. The muffle furnace mainly uses this bias of gas molecules to separate different gases. The structure and working principle of the

muffle furnace

muffle furnace usually consists of two sealed cylindrical chambers separated by a thin hole partition. The first chamber is filled with the mixed gas, and the second chamber has an outlet for collecting the separated gas. When the first cavity is heated to a high temperature and high pressure state, the gas molecules begin to move thermally, and some of them will use the muffle effect to move toward the fluid region during collision. Gas that is more easily biased toward the fluid area will enter the second chamber through the pores in the partition plate, and the separated gas can be collected through the outlet. The separation efficiency of the muffle depends on a variety of factors, including temperature, pressure, the size of the pores of the separator, and so on. The application
of

muffle furnace
muffle furnace is widely used in industrial separation technology, especially in air separation, industrial gas production and the preparation of pure oxygen and hydrogen. At the same time, the muffle furnace can also be used to detect the composition of the gas mixture.

summary The

muffle furnace is an important equipment for gas separation. Its principle is based on the discovery of Rudolf Muffer and has become one of the important methods of industrial separation technology. With the continuous progress of science and technology, the performance of the muffle furnace will continue to improve, making its application in the field of gas separation has been continuously expanded and deepened.
