This article discusses the direction of energy conservation through the development of new designs of heating and heat treatment furnaces. In particular, we consider the design of chamber heat treating furnace with shared working space. If necessary, reducing the volume of the working space of the furnace, due to the small cages mounted on the hearth removable partition which separates the working space of the furnace into two chambers 6 m long and 12.6 m baffle is installed in a particular recess, located in the hearth and laying a fixed by stretch marks. If you need to handle long items partition is removed, and formed on the hearth void is filled with a filler. The results of the tests of a new furnace design in industrial environments that have shown performance and energy efficiency of the proposed design of the furnace.
