The Furnaces allow accurate measurement of materials at high and low temperatures, to ensure optimal performance under those conditions. Two furnaces are available, one providing temperatures from °C to °C (Low Temperature Cell, LTC), the other from room temperature up to °C (High Temperature Furnace, HTF).

key to efficient furnace operation lies in High temperature furnace modeling and performance verifications book combustion of fuel with minimum excess air. Furnaces operate with efficiencies as low as 7% as against upto 90% achievable in other combustion equipment such as boiler.

This is because of the high temperature at which the furnaces have to operate to meet the required demand. A heating element is used to convert electricity into heat, and within an industrial furnace, there are various materials that can be atheizm.comlly, iron-chrome aluminum or nickel chrome alloys are used in furnaces, and the standard shapes are cylindrical, semi-circular, or flat atheizm.com blog post will look at the other different types of materials that can be used as high temperature.
