Abstract
An engine exhaust-driven heating device generates a high volume, steady stream of hot gas by passing an exhaust stream from a gasoline, propane, natural gas, or combustible fueled internal combustion engine through a catalyst that reduces the atmospheric emissions of the stream and liberates the energy of the pollutants in the stream. The device then combines the catalytic-treated air stream with a fresh air stream to further react with remaining pollutants and generate additional heat. The hot gas may be used to dry a variety of surfaces and, when integrated without other components typically found in surface drying equipment, provides an ideal system for use in a variety of moderate- to large-sized portable surface drying equipment. The heating device provides a reliable and continuous heat source and, when integrated into a controlled delivery system, dries the moisture from a surface faster and more effectively than prior art heating devices.
