The specification discloses and describes a method and means of operating an incinerator whereby the concentration of evaporated solvent or other combustible materials delivered to an incinerator is controlled as a reflection of the temperature of the gas stream made up of products of combustion exhausted from the incinerator. By maintaining the fuel input to the incinerator constant and also maintaining the temperature of the stream of gases entering the incinerator constant, the variation of the temperature of the stream of products of combustion emitted from the incinerator with respect to a standard value reflects the variation in the concentration of evaporated solvents or other combustibles in the stream of gases supplied to the incinerator. A valve means, responsively controlled according to the temperature of the stream of products of combustion emitted from the incinerator, functions to regulate the quantity of the stream of gases including diluents, such as air, admitted to the incinerator, thereby regulating the concentration of evaporated solvent and other combustibles evolved to a substantially constant and safe value and incidentally controlling to a uniform temperature the stream of gas products of combustion at the outlet of the incinerator. The method and means may be used in connection with ovens employed in a drying process wherein combustible material of vaporous, solid or liquid form, are carried in a gaseous stream to the incinerator.
