Abstract
Improved air port castings are employed in a recovery boiler, eliminating the use of a crotch plate in a membrane/tube type boiler. The casting extends over the exposed portion where the membrane begins again at an air port, providing a sacrificial member that is replaceable. An upper mounting bolt is employed, but no lower bolt is required, making replacement of the casting simpler. A damper guide is formed as an integral portion of the air port casting.
