Engine exhaust-driven heating device for use in portable surface drying equipment

摘要

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.

主权项

1. A portable heating system comprising:
a catalytic chamber (15) housing at least one catalyst (3) and arranged to receive an exhaust gas stream; a baffled mixing chamber (5) arranged to receive a catalytic-treated exhaust gas stream from the catalytic chamber and mix the catalytic-treated exhaust gas stream with an ambient air stream; and a distribution chamber (6) arranged to receive a mixed gas stream from the baffled mixing chamber and direct it toward a surface to be dried.
