ABSTRACT:
A heat recovery device for recovering waste heat from a hot gas that carries solid and precipitable contaminants of the type given off from the grill area of a fast food restaurant in which a heat exchanger is provided through which these gases are directed for heat exchange with a gas to be heated such as ambient air. The heated air may then be supplied to the interior of the restaurant or to ambient. The two gases are directed through sets of spaced passages in the heat exchanger in heat exchange relationship with each other. A filter is used ahead of the heat exchanger for filtering the hot gas. This filter is easily removed for cleaning. A liquid receiving container may be periodically used to replace the filter. This receives a liquid such as a hot detergent solution that may be used to clean the contaminated passages of the heat exchanger.
