Abstract
A synthesis gas cooler has concentric water walls to provide for heat transfer to a fluid in the water wall tubes. The inner water wall is concentric with the cooler shell and has a gas tight inlet connection for introducing hot synthesis gas. The inlet is located at the top of the shell. The bottom of the shell contains a body of water for quenching entrained solids which are carried with the synthesis gas, and there is a baffle to direct the flow of synthesis gas back up in the annulus between the two concentric water walls. The annulus has a closed upper end except for an outlet for the synthesis gas which is located near that end of the annulus. Also, there may be soot blowers along the length of the water walls to keep the heat transfer surfaces clean.
