Abstract
Hot fluids are cooled in a heat exchanger which comprises a housing providing a passage for the hot fluid, and heat exchange surfaces arranged within the housing which surfaces provide a passage for a coolant to and from the housing such that there is no direct contact between the hot fluid and the coolant, and which surfaces are movable within the housing. The heat exchanger is very suitable for cooling synthesis gas obtained in the gasification of coal.
