Generating Electricity from Waste Heat of
CPH-Systems or Solarthermic Systems
(Collectors / Mirrors)

A new development by ARMAK GmbH of Kornwestheim, Germany, allows the conversion of such heat into electric power. Even the exhaust of combustion engines in Combined Power and Heat plants can be converted into electricity.

Those engines have efficiencies below 40%. That means that about another 60% are wasted by exhaust gases. The conversion even of part of such energy into electricity is of major advantage.

ARMAK Steam Motors are still under development, because of the need for a stainless design. At this time no supply date can be estimated.

This is were ARMAK Gas Pressure Motors are used, operating with coolants instead of steam. They require a pressure from 6 to 15 bar. To obtain this, heat is transferred to the heat exchangers. A suitable fluid is accurately metered and evaporated. Pressures up to 15 bar can be obtained in this way, sufficient to drive the ARMAK motor and an electric generator coupled to this motor. ARMAk GmbH is developing such an ORC-System which should be ready late in 2012.

ARMAK Gas Pressure Motors GGP04 and GGP16 can be supplied.
