Abstract
A flow heater comprises a heating element (48; 248) and a first heating region (18, 20; 218, 220) heated by the heating element (48; 248) for heating liquid flowing therethrough to a first temperature below boiling. The flow heater also comprises a second heating region (22; 222) for heating the liquid to a second temperature below boiling. The second region (22; 222) has means (25; 225) for permitting the exit of steam therefrom separately from heated liquid. The flow heater cannot be operated so that bulk boiling of said liquid takes place in the second region (22; 222).
Claims28
A flow heater comprising a heating element, a first heating region heated by said heating element for heating liquid flowing therethrough to a first temperature below boiling, and a second heating region for heating said liquid to a second temperature below boiling, said second region being arranged to permit the exit of steam therefrom separately from heated liquid, wherein said flow heater cannot be operated so that bulk boiling of said liquid takes place in the second region.
A flow heater comprising a heated flow conduit for heating liquid therein to a first temperature below boiling and a final heating chamber for heating said liquid to a second temperature below boiling wherein said heating chamber comprises a space above the liquid surface for allowing the escape of steam from the liquid surface wherein said flow heater cannot be operated so that bulk boiling of said liquid takes place in the final heating chamber.
