Plate Condenser

Tests have been performed with a Plate Condenser, which was installed within the Condenser Tank, see Fig. 10. The atmosphere tested was pure steam, a mixture of steam and oxygen, a mixture of steam and helium and a mixture of steam, oxygen and helium.

In Fig. 11 the influence of the non-condensables on the transferred power is shown. Fig. 12 shows one test with steam and oxygen, showing an accumulation in the lower part of the tank.
