Excess exothermic heat is removed as usual by indirect heat exchange of the reacting material with steam. In this case the steam is passed into the cooling chamber in a wet state saturated with H₂O up to 60% and 80% of its capacity. It is advantageous to maintain the wet steam under such pressure that the saturation temperature lies only slightly below the reaction temperature.
