Abstract
A drying oven for painted surfaces wherein the work is heated and dried by heated, high pressurized air blown against the work as it passes through the oven. A plurality of elongated pipes, each of which have a plurality of nozzle openings therealong, direct the air against the work. The heat of incineration of the solvents stripped from the work is recovered for makeup heated air to the furnace. One or more ceramic rotary heat exchangers are used to transfer the heat from the incineration exhaust gases to the fresh air. Energy required for circulating air through the furnace is minimized by supplying makeup air with a fan to a cold side of the rotary ceramic heat exchanger.
