METHOD FOR SIMULTANEOUSLY FORMING ELECTRICAL ENERGY AND HEAT FOR HEATING, AND PLANT FOR CARRYING OUT THE METHOD

摘要

PROBLEM TO BE SOLVED: To provide a method for simultaneously forming electrical energy and heat for heating and including the use of a fuel cell for forming large quantities of heat for heating of room in particularly winter and a gas burner and for carrying out simultaneous formation of electricity using the fuel cell on maximized power level and to provide a plant for carrying out the method. SOLUTION: Electrical energy and heat are simultaneously formed from a combustion gas G consisting mainly of at least one hydrocarbon and an oxygen-containing gas mixture A. The quantity less than half the combustion gas G is converted in a battery C having a fuel cell to form electricity and to form a first exhaust gas. The remained quantity is burned in a burner B to form a second exhaust gas. The first exhaust gas is at least partially used as an oxygen source for combustion. Thus, heat energy is recovered from a plurality of exhaust gases. In addition, at least about half quantity of water contained in the exhaust gases is condensed.
