Definitions

  • Our invention is based on energy efficiency (7) of the boiler systems (26) that are currently a boiler system itself as a whole, on closed and semi-closed (4-3-5) (8-9-18-19-20-21-25) circuits, and on directly effective usage of just only generated energy from the boiler, and on gained huge energy (10-11) that occurs from its usage.

  • This water shows its functions for absorption (7) of inner heat of boiler (26) and for providing of combustion balance (7).
  • Water (24) with its functions plays an important role on providing of inner fluid balance (7-26) of the boiler. This explains why we named our invention as CHP-W.
  • Heat (7) that is very fluidic and whose control is very hard needs water (24) to stick so that it is movable to on the way going to power (10-11) production.
  • the relationship between heat (7) and power (10-11) depends on binding of water (24) to balance the heat and power that corresponds to boiler efficiency (26).

  • Cogeneration is a method which uses rest energy resulted from the heat and steam that is needed by production line
  • our invention is a method that uses the resting heat and steam of electricity generation in the production line.
  • Our invention is contradiction to the process of cogeneration.
  • the flue gas should be discharged in periodical intervals in cogeneration systems either to use it at the various phases of production line if flue gas is not totally left to the atmosphere directly or to balance inner combustion of boiler.

  • Cogeneration systems cannot benefit from energy gaining in any phases via enthalpy of superheated steam because they must be fed with restricted superheated steam (8-18-19). Because of existence of the appropriate superheated steam amount potential (8-9-16) of our invented project solutions, our invention will benefit from the enthalpy of superheated steam in places (8-16-18-19) in terms of general system integrity.

Abstract

Des centres de production d'énergie (26) en termes d'échelle industrielle (14) sont établis dans des établissements industriels afin de fournir de la chaleur (7) et de l'énergie-vapeur (18-19) qui sont nécessaires pendant les différentes phases de production industrielle. Ces centres sont bien connus sous le nom de chaudières (26). Les chaudières (26), qui ont été améliorées pendant de nombreuses années, ont été utilisées uniquement pour générer de la chaleur et de la vapeur dans des processus de production (14) pour faire face à la demande. Etant donné que l'énergie produite (7) n'a jamais été régénérée en tant qu'énergie auto-transformée (7) (8- 18-19-21) dans des phases quelconques, les chaudières provoquaient de grandes pertes d'énergie (29). Après cette période, un nouveau système a été mis au point, appelé cogénération (CHP). Ce système a été amélioré sur la base de deux concepts. La vapeur surchauffée nécessaire, destinée à la production d'électricité, est produite soit à partir du gaz de fumée (29) dont le rapport CO2-CO est plus élevé et qui est expulsé de la chaudière, soit à partir de la chaleur qui reste dans la chaîne de production (14) en tant qu'énergie thermique élevée inerte. En plus de ces deux concepts similaires en termes de CHP, il existe un autre procédé qui peut être utilisé pour générer de la vapeur surchauffée qui est destinée à régler des échangeurs et surchauffeurs dans la chaudière. Jusqu'à présent, personne n'avait trop réfléchi à placer le système de génération d'énergie électrique (10-11) au centre de la chaudière (26), ce qui est nécessaire à une production à l'échelle industrielle (14), les autres besoins en énergie et autres systèmes (4-3-5) (16- 19) étant conçus de manière interdépendante. Alors que, une fois cela réalisé, avec la même taille de chaudière et la même quantité de combustible, davantage d'énergie électrique serait générée par rapport à l'énergie électrique (10-11) qui est générée par cogénération-CHP. De plus, les besoins de la totalité de la chaleur (7) et de la vapeur (8-18-19), qui sont nécessaires pour la chaîne de production, seraient couverts. La structure de la chaudière (26) est conçue pour produire de l'énergie électrique (10-11), et si on obtient un gain de vapeur surchauffée (89) et/ou de types de vapeur (16) qui sont réutilisés dans les différentes phases de la chaîne de production (18- 19), le rapport de l'unité/temps de l'énergie électrique va s'élever d'au moins 60 % par rapport à la génération par cogénération (CHP). En résumé, l'invention concernant la génération d'électricité (10-11) est basée sur la prise en considération des entrées des chaudières (26) (7) (8- 9) à la place des sorties des chaudières. Compte-tenu des entrées des chaudières, des moyens permettent de reconcevoir la structure de la chaudière (26), le rendement de la chaudière (7), l'utilisation de l'énergie et son fonctionnement (4-3-5) (8-9- 16) et, de cette manière, de tenir compte de l'énergie requise (7) en chaleur et vapeur (8-1819) également, dans la chaîne de production, en utilisant les principes fondamentaux du procédé de cogénération-W. Ainsi, la cogénération-W de l'invention a été mise au point en tant que système alternatif constituant une solution à la cogénération (CHP). Et l'obtention d'énergie (4-3-5) (16) et la capacité de génération d'électricité (10-11) tirée du gain en énergie présentent un meilleur rendement du fait que le nouveau système apporte des changements au procédé courant; le système de l'invention présente de bien meilleures caractéristiques de productivité et d'efficacité, ce qui dépasse la portée du contenu.
