Abstract
A tube heat exchanger for the production of carbon black includes a support plate located at the lower end of a space through which heat exchanger tubes extend. The plate includes upper and lower spar support plates forming a spar space therebetween through which the heat exchanger tubes extend. The spar space is divided into a plurality of canals by partition walls. Each canal has its own inlet and outlet for conducting a flow of cooling medium. The flow direction of cooling medium in each canal is opposite that of an adjacent canal. Portions of the support plate are formed of an aluminum-containing, iron-based alloy produced powder-metallurgically.
