The Air Cooling of Tank Blocks

JSGT 1939 V23 T108-T115

 The paper attempts to calculate the temperature distribution through tank blocks for certain assumed temperatures within the tank and outside it. The basis of the calculation is that the three quantities of heat (a) transferred to the inner surface of the blocks, (b) conducted through the blocks, and (c) dissipated from the outer surface of the blocks, must be equal. Relative measurements are also given for the rate of corrosion of refractories at different temperatures and from these and the temperatures calculated as indicated above, an estimate of the change of thickness of the blocks with time is obtained by numerical integration. The calculations suggest that forced air cooling is of no value in the early stages of the life of a tank and makes relatively small difference to the temperature of the inner surface even when the blocks are reduced very considerably in thickness.
