Abstract
A heat exchange unit for hot gas heat recovery has a heat exchange array situated within a heat exchange duct defined between a cylindrical outer casing and an axially slidable inner sleeve. The sleeve, together with a plug valve at the upper end of the unit, forms a variable position sleeve valve arrangement which simultaneously controls the flow of hot gas through the heat exchange duct and the bypass duct.
