ABSTRACT:
A heat exchanger with a set of channels through which grease laden air travels. Relatively cool air passes through the heat exchanger in a second set of channels. Washing means including liquid tubes within the first set of channels is provided for washing collected grease from the surfaces defining the first set of channels. A cooking facility including a hood for collecting grease laden air connected to a heat exchanger. Relatively cool air from an outside source passes through the heat exchanger to promote the collection of grease in the exchanges from the grease laden air received from the hood. The air from the outside source is raised in temperature on passing through the exchanger. Such heated air may be used as a source of heat for heating a building enclosure.
