Abstract
An arrangement for cooling vessel portions of a furnace (1) having a cooling box which is fitted into a wall or cover region to be cooled or which forms a wall or cover region and which, towards the furnace interior (6), includes a heat exchange plate (2) which is acted upon with cooling fluid through a plurality of spray nozzles (3). The heat exchange plate (2) is in the form of a composite plate comprising a steel plate (8) on the side towards the furnace interior (6) and a copper layer (9) on the side of the spray nozzles.
Claims11
An arrangement for cooling vessel portions of a furnace comprising
- a cooling box which is fitted into a wall or cover region to be cooled or which forms a wall or cover region and which, towards the interior of the furnace, has a heat exchange plate and, in opposite relationship thereto and spatially distributed, a plurality of spray nozzles for spraying a cooling fluid onto the heat exchange plate, and also an outlet for the cooling fluid, wherein
- the heat exchange plate is in the form of a composite plate, with a steel plate on the side which is towards the furnace interior and, on the side towards the spray nozzles, a layer of metal which has substantially higher level of thermal conductivity than steel.
A cooling vessel portion of a furnace comprising
- a cooling box having a wall forming a heat exchange plate having one side exposed to an interior portion of said furnace and a plurality of spray nozzles for spraying a cooling fluid onto the opposite side of said heat exchange plate,
- wherein said heat exchange plate is a composite plate having a steel layer on said one side being exposed to the interior of said furnace and a layer of metal having a substantially higher level of thermal conductivity than steel on said opposite side exposed to said spray of said spray nozzles to promote uniform cooling of said heat exchange plate.
A cooling vessel for cooling a furnace having a heat exchange plate means for forming a wall of said furnace, said heat exchange plate means including a first side exposed to an interior portion of said furnace and a second side, opposite said first side, exposed to a coolant spray, wherein said heat exchange plate means is composite plate comprising
- A. a base metal layer on said first side exposed to said interior portion of said furnace, and
- B. layer means, on said second side, having a substantially higher thermal conductivity than said base metal layer for producing uniform cooling of said heat exchange plate means.
