Fireproof form brick for combustion chamber inner cladding

摘要

On the rear side of each brick (2) is a recess (6) in which the tube (7) is located. The brick itself is U-shaped and the free ends of the two U-arms (10) are directed towards the outside of the combustion chamber. The U-arms partly or completely laterally cover over the tube (7). The front sides of the form bricks forming the combustion chamber inner wall are arched forwardly to the combustion chamber, particularly convexly, whereby the areas extending furthest into the combustion chamber are located in front of the tubes. The arching (3) is the part surface of a cylinder the axis (16) of which is located behind the axis (17) of the tube.
