Jamaluddin, A A

A system of air pollution control and heat recovery is provided for an arrangement of industrial ovens, especially for drum manufacture. A plurality of paint bake ovens of various capacities, lengths and heat input are provided for multi-stage processing in the manufacture of drums and lids therefor. A supply of high temperature water is provided for multi-stage cleaning and rinsing in the manufacturing operation. The combined exhaust from the oven is preheated in a heat exchanger and then all of the combustible components are burnt off by passing through the flames of an incinerator grid burner. The effluent from the burner first passes through the heat exchanger to preheat said oven exhaust gases and then through hot water coils to provide all of the necessary hot water for the system. High pressure hot water (275/sup 0/) is provided in this heat exchange operation. The hot gasses from the last heat exchanger, completely free of combustible contaminates, are mixed with fresh air to supply hot air for the dryers used in the process. There is a substantially complete recovery of heat and the gasses discharged to atmosphere meet air quality standards.
