Title (EN) RETROFITTING COAL-FIRED POWER GENERATION SYSTEMS WITH HYDROGEN COMBUSTORS
(FR) RATTRAPAGE DE SYSTEMES DE PRODUCTION D'ENERGIE AU CHARBON PAR SYSTEMES DE COMBUSTION A L'HYDROGENE
Abstract:
(EN) A method of retrofitting a power generation system having a coal-fired steam boiler, a steam turbine system, and a condenser comprising installing a hydrogen-fired combustion system therein having the step of replacing the coal-fired steam boiler with a hydrogen-fired combustion system such that a steam flow generated by the hydrogen-fired combustion system is directed to the steam turbine system. Another method of retrofitting a power generation system has the steps of installing a hydrogen-fired combustion system to receive the steam flow, a hydrogen stream, and an oxygen stream, and to produce a super-heated steam flow therefrom; and installing a new steam turbine system capable of receiving and expanding said super-heated steam flow and directing said expanded super-heated steam flow to at least a portion of said original steam turbine system.
(FR) L'invention concerne un procédé de rattrapage d'un système de production d'énergie à générateur de vapeur au charbon, système de turbine à vapeur et condenseur, qui consiste à installer un système de combustion à l'hydrogène à l'intérieur dudit système, le principe visant à remplacer le générateur de vapeur au charbon par un système de combustion à l'hydrogène, de sorte que celui-ci fournisse un flux de vapeur au système de turbine à vapeur. Un autre procédé de rattrapage de système de production d'énergie comprend les étapes suivantes: installation d'un système de combustion à l'hydrogène pour recevoir le flux de vapeur, un flux d'hydrogène et un flux d'oxygène, et à partir de là pour produire un flux de vapeur surchauffée; et installation d'un nouveau système de turbine à vapeur capable d'assurer la réception et l'expansion du flux de vapeur surchauffée, puis de diriger ledit flux après expansion vers au moins une partie dudit système initial de turbine à vapeur.
