The relevance of optimization of thermal operation and design of furnace plants with a chamber high-temperature metal heat treatment regime is considered. The methodology of their comprehensive optimization is given. The complex optimization of the furnace unit is part of an interrelated and complex evaluation of the influence of each element of its functional scheme on the thermal performance of the plant. The functional scheme of the kiln installation includes the fuel supply and heating system, the equipment of the air supply system with a recuperator for heating the air going to burn the fuel, the system of disposal in the environment of the leaving from the working space. The development of fuel combustion products with equipment for their low-temperature recycling. The method of complex optimization of furnace installation allows to determine the values of optimal parameters of thermal operation and design of furnace installations on the basis of system analysis and system approach. The method ensures the establishment of an optimal relationship between fuel consumption, metal oxidation losses, total costs for heat treatment quality of the metal, achievement of optimum proportions in the distribution of investments between individual units and elements of the furnace plant. This optimizes the internal structure of the furnace system. A functional scheme of the furnace installation and a schematic for its complex optimization when solving the problem of its feasible design are proposed.
