Improvements in regenerative heating systems.

摘要

A regenerative heating system includes at least a pair of regenerators (1) and (2) of the type which are operable so that while one is being heated by waste gas the other is heating air for the combustion of fuel.

The system includes a pair of regenerators (1) and (2) which are interconnected adjacent one end to form a chamber (4) having an outlet (8) to discharge waste gas flow into the chamber (4) from one or other of the regenerators (1) or (2). Air nozzles (7) extend into the chamber (4) to inject air into the regenerators (1) or (2) during the air heating cycle of regenerator (1) or (2). The waste gas may be removed by the suction force of a fan or eductor.
