Title (EN) SUPERCRITICAL CARBON DIOXIDE POWER GENERATION SYSTEM USING PLURALITY OF HEAT SOURCES
(FR) SYSTÈME DE PRODUCTION D'ÉNERGIE GRÂCE À DU DIOXYDE DE CARBONE SUPERCRITIQUE METTANT EN OEUVRE UNE PLURALITÉ DE SOURCES DE CHALEUR

Abstract:
(EN) The present invention relates to a supercritical carbon dioxide power generation system using a plurality of heat sources, comprising: a pump for circulating a working fluid; a plurality of heat exchangers for heating the working fluid through external heat sources; a plurality of turbines driven by the working fluid which has been heated by passing through the heat exchangers; and a plurality of recuperators for cooling the working fluid by performing a heat exchange between the working fluid that has passed through the turbine and the working fluid that has passed through the pump, wherein the heat exchanger includes a plurality of constrained heat exchangers which are heat sources using heat from waste heat gas discharged from a waste heat source and having a discharge regulation condition of a discharge end, wherein the combined flow (mt0) of the working fluid is supplied to the recuperators. According to the present invention, by effectively arranging each of the heat exchangers in accordance with conditions such as the inlet/outlet temperature, the capacity, and the number of heat sources, the number of recuperators used can be the same as or lower than the number of heat sources, thereby providing the advantages of simplifying the composition of the system and enabling effective operation.
(FR) La présente invention concerne un système de production d'énergie grâce à du dioxyde de carbone supercritique mettant en oeuvre une pluralité de sources de chaleur, lequel système comprend : une pompe destinée à faire circuler un fluide de travail; une pluralité d'échangeurs de chaleur destinés à faire s'échauffer le fluide de travail par le biais de sources de chaleur externes; une pluralité de turbines entraînées par le fluide de travail qui s'est échauffé en ayant circulé dans les échangeurs de chaleur; et une pluralité de récupérateurs destinés à faire refroidir le fluide de travail en effectuant un échange de chaleur entre le fluide de travail ayant circulé dans la turbine et le fluide de travail ayant circulé dans la pompe, l'échangeur de chaleur comprenant une pluralité d'échangeurs de chaleur à contraintes qui sont des sources de chaleur utilisant la chaleur issue d'un gaz à chaleur perdue rejeté par une source de chaleur perdue et dont une extrémité de rejet présente une condition de régulation de rejet, le flux combiné (mt0) du fluide de travail étant amené aux récupérateurs. Selon la présente invention, grâce à un agencement efficace de chacun des échangeurs de chaleur en fonction de conditions telles que la température d'entrée/sortie, la capacité et le nombre de sources de chaleur, le nombre de récupérateurs utilisés peut être égal ou inférieur au nombre de sources de chaleur, ce qui offre les avantages de simplifier la composition du système et de permettre un fonctionnement efficace.
(KO) 본 발명은 복수의 열원을 활용한 초임계 이산화탄소 발전 시스템에 관한 것으로, 작동 유체를 순환시키는 펌프와, 외부의 열원을 통해 상기 작동 유체를 가열하는 복수의 열교환기와, 상기 열교환기를 통과해 가열된 상기 작동 유체에 의해 구동되는 복수의 터빈과, 상기 터빈을 통과한 상기 작동 유체와 상기 펌프를 통과한 상기 작동 유체를 열교환하여 상기 터빈을 통과한 상기 작동 유체를 냉각시키는 복수의 리큐퍼레이터를 포함하며, 상기 열교환기는 폐열원으로부터 배출되는 폐열 기체의 열을 이용하는 열원이며, 배출단의 배출 규제 조건을 갖는 복수의 제한 열교환기를 포함하고, 상기 작동 유체의 통합 유량(mt0)이 상기 리큐퍼레이터로 공급되는 것을 특징으로 한다. 본 발명에 따르면, 열원의 입출구 온도, 용량, 개수 등의 조건에 따라 각 열교환기를 효과적으로 배치함으로써 열원의 개수 대비 동일하거나 적은 수의 리큐퍼레이터를 이용할 수 있어 시스템 구성이 간소화되고 효과적인 운영이 가능한 장점이 있다.
