Abstract
A shaft cooler for dry quenching of coke includes an inner masonry ring that is an independent structure suspended on the top edge of the outer masonry of the shaft cooler. The weight of the inner masonry ring is carried by stays which bear on the top edge of the outer masonry. The tubular stays are disposed in one embodiment inside the masonry ring and in another embodiment outside the masonry ring. The tubular stays are connected to ring mains for conducting a coolant medium. When the tubular stays are disposed outside the masonry ring, parallel tubes are interconnected along their entire length by webs to form a closed steel ring. Ring tubes are welded to the top and bottom ends to serve as a heat exchanger and are connected to the evaporator section of a waste-heat boiler of the shaft cooler. Flue-gas passages are formed at the bottom edge of the masonry ring by radially, spaced-apart webs.
