Preservation and use of heat generated during various technological processes is a priority for most modern industrial enterprises. This is especially true for the metallurgical industry and other high temperature industries, where temperatures reach thousands or more degrees, here the heat losses are especially high.
The best solution to the problem is to use industrial heat exchangers, units in which the heat from the outgoing hot gases is transferred to the incoming air flows, heat exchange occurs due to the border surfaces of the channels.
Not all types of heat exchangers are suitable for high-temperature industries such as metallurgy, glass industry and a number of others due to special conditions. The most suitable type of the recuperator is a coaxial, or double shell recuperator.
