OPERATING PROCESS OF HEAT-AND-POWER COGENERATION PLANT Russian patent published in 2003 - IPC

FIELD: mechanical engineering; cogeneration plants. SUBSTANCE: proposed operating process includes supply of heated atmospheric air and hydrogen-containing gas to electrochemical generator loops, electrochemical reaction for electrical energy generation to feed power loads, and production of high-temperature mixture of steam and carbon dioxide, bifurcation of the latter, supply of first flow to thermochemical reformer for generating hydrogen-containing gas from hydrocarbon fuel, delivery of second flow to gas loop of exhaust-heat boiler to produce heat in its water loop in the form of steam or hot water to feed heat loads; electric current is produced in electric generator driven by internal-combustion engine during period when electrochemical generator is gaining rated conditions. EFFECT: reduced time for power plant starting and gaining rated power; enhanced operating efficiency of plant. 1 cl, 1 dwg
