ROGERS, BERESKIN & PARR Title: PULSE COMBUSTION APPARATUS Inventor: JOHN A. KITCHEN ABSTRACT OF THE DISCLOSURE The disclosure relates to pulse combustion apparatus generally and to air furnaces of the pulse combustion type. The invention provides a furnace which in- cludes a combustion chamber and an exhaust system disposed in a passageway for air to be heated. The exhaust system includes a primary exhaust pipe, a manifold to which the primary exhaust pipe is coupled, and a plurality of heat exchange pipes which extend from the manifold across the air passageway. The primary exhaust pipe, manifold and heat exchange pipes form a reasonant system with the com- bustion chamber so that the ignition of successive fuel charges in the chamber causes pressure waves to oscillate throughout said exhaust system including the heat exchange pipes for promoting transfer of heat from the pipes to air flowing through the passageway in use.
