A method of detecting leaks at kuehlkaesten in pressureless verdampfungskuehlsystemen on shaft furnaces, in particular highly an oven, and use in the case of blast pipe - kuehl - and slags shapes

摘要

Leaks are detected by means of a higher pressure (3-4 atm) circuit in parallel with the main circuit. The test circuit is switched in to replace the ordinary circuit and a rotameter indicates whether there is a leak or not. By isolating the different elements of a cooling circuit in turn, the faulty one can easily be detected.
