Muffle Furnace
A muffle furnace, also known as a retort furnace, is a piece of oven-type equipment that can reach high temperatures. It usually works by putting a high-temperature heating coil in an insulating material. The insulating material effectively acts as a muffle, preventing heat from escaping.
How does a muffle furnace work?
A Muffle furnace allows rapid high-temperature heating, recovery, and cooling in self-contained, energy-efficient cabinets. A muffle furnace separates the object to be heated from all byproducts of combustion from the heat source. In modern electrical furnaces, a radiation or convection energy applies heat to a chamber using a high-temperature heating coil inside insulated material. The insulating material effectively acts as a muffle, preventing heat from escaping.
