Cermak's invention relates to a method of and to arrangements for cooling the
walls of combustion spaces and other spaces subject to high thermal stresses, such as
combustion. chambers, melting chambers and the like. In the arrangement shown in
Figures 1 and 1A, the wall 1 defines a combustion space or other thermally highly
stressed space which is divided into individual cooled wall members. Each member
forms at its outer side a collecting chamber 6 and at its inner side a distribution
chamber 4, both chambers having either an independent inlet or outlet for the cooling
medium respectively. In the example shown it is the inlet 2 and the outlet 3 for the
coolant. The latter acts an the wall 1, to be cooled, by means of several concentrated
jets emerging from nozzles 5. The nozzles 5 are attached to the distribution chamber 4
for the coolant. The cooling medium strikes the cooled wall 1 at a relatively high
velocity substantially at right angles, is collected in the collecting chamber 6 and
withdrawn through the outlet 3 from the wall member. In the arrangement shown in
Figure 2, the metallic partition 1 of the combustion or other thermally highly stressed
space is provided with cylindrical cooling pockets 7. The nozzles 5 are connected to
the distribution chamber 4 and protrude into the cooling pockets 7. The outflowing
coolant strikes at a relatively high velocity the bottom of the cooling pocket 7 in a similar
manner as in Figures 1 and 1A. The cooling medium flows from the cooling pocket 7
immediately into the coIIecting chamber 6, from where it is withdrawn through the outlet
3 for further use, e.g., as combustion supporting medium.
