Abstract:
A plant comprising high temperature fuel cells which form a battery in which electrochemical reactions are carried out with a fuel and a gas including oxygen while producing an electrical current and hot exhaust gas which transports waste heat, the plant comprising a device including a circulation system in which a heat carrier medium flows; a first heat exchanger for transferring waste heat from the exhaust gas to the heat carrier medium resulting in a heated heat carrier medium furnishing heat to a user device capable of using a limited amount of heat while cooling the exhaust gas not to exceed a predetermined temperature so that the exhaust gas can be discharged without causing damage; and a second heat exchanger for removing heat from the heat carrier medium to regulate the amount of heat furnished to the user device not to exceed the limited amount of heat, the second heat exchanger transferring heat removed from the heat carrier medium to a secondary gas flow that can be discharged without causing damage.
