Abstract
Combustion products containing particulate solids such as carbon black are quenched by indirect heat exchange and the build up of solids deposits on the heat exchange surfaces is minimized or deposits on the heat exchange surfaces are removed by providing a fixed bed of fluidizable particulate solids within the indirect heat exchanger and positioning a shell-tube heat exchanger within the bed of solids with the heat exchange fluid being in the shell side and with the gas stream containing entrained solids such as carbon black passing through the tubes which contain particulate solids. Fluidization of the particulate solids by the gas stream containing carbon black, for example, passing through the tubes cleans or keeps the inner peripheries of the tubes clean.
