    摘要: An apparatus and a method for inhibiting metal dusting corrosion of a tubesheet inside a shell-and-tube heat exchanger having at least one exit nozzle for transmitting at least one process fluid from the shell-and-tube heat exchanger include and use: an isolation baffle disposed inside the shell-and-tube heat exchanger at a location between a first exit nozzle and the tubesheet, whereby an isolated space exists between the tubesheet and the isolation baffle; and a means for purging the isolated space with a purging fluid.
