A process for the recovery of energy from a fluid stream comprises continuously adding fuel in such a quantity to the fluid stream that the ratio of fuel to oxygen present remains substantially stoichiometric, passing the so-produced mixture through a heat exchanger having on one or more heat exchange surfaces thereof a catalytic layer such that at least the fuel in the said mixture undergoes catalytic oxidation, and removing at least a part of the heat originally present in the fluid and of the heat produced by the catalytic oxidation. An oxygen sensor may be provided in the inlet, coupled to a means for varying the proportion of fuel in the input. The catalyst is preferably a wash-coated heat exchanger (Figure 1) with a surface layer of platinum group metal catalyst plus a base metal additive. <IMAGE>
