  • the energy generation method CHP-w is in accordance with the first law of thermodynamics. In fact, it formulizes to its own internal running of the mechanism providing that to be established the proportional relationship between heat and extra work/ electricity within this frame of mathematical equation. It do does this, too on the basis of the following question; how should I establish the thermodynamics relationship between the total generated heat energy and the work/ electricity in closed circuit system so that I can obtain the maksimum work output? Because there is a direct proportional relationship between heat and the work this is a question that must be answered based on thermodynamics. At first sight the answer can be given either as an increase in the initial heat energy or as being used of the heat energy in the boiler in the work generation.
  • CHP-w is the solution of suppling heat and steam energy demanded by the production line and at the same time generating more electricity than Cogeneration with the same amount of fuel.
  • CHP-w does not aim to reduce fuel costs by converting the increase in efficiency to energy saving, since a probable shrinkage in the amount of total calorie-generated heat energy leads to work loss. Therefore, it aspires to preserve the magnitude of the current system. On top of that, preferably on condition that arising the boiler size (26), owing to knowing of much more rising of total energy efficiency in proportional basis, it voluntarily gives support to increasing of boiler capacity. Moreover, the general concept that is formed on is very suitable to produce a solution intended to capacity increasing. It collects to the total heat in a single hand and uses it to create additional work/ capacity.
  • CHP-w defines this as heat energy trapping in the boiler. If a significant part of heat energy of which the production line requires is obtained from steam with low pressure-relatively high entalphy through heat transfer "steam exchanger" procedure. CHP-w refers to this method with the same terms as "gradual and circular usage” that it uses for the flue gas circulation.

Abstract

L'état de base de la thermodynamique est qu'il est fermé. Ceci constitue une condition préalable principale pour qu'un système de thermodynamique puisse être mesurable et contrôlable. Ceci est la base sur laquelle la CHP-w a été mise en place. Il ne devrait pas y avoir de mauvaise conception concernant la CHP-w comme celle de savoir comment une égalité thermodynamique peut produire plus de travail en sens inverse. De fait, une égalité doit être identique des deux côtés. Cependant, la cogénération et la cogénération-w ne sont pas deux côtés d'une égalité. La cogénération et la cogénération-w sont constituées d'une équation séparée en elle-même. La cogénération est un procédé de récupération de la chaleur en utilisant des paramètres thermodynamiques qui ont chuté dans un état inerte dans un système ouvert. Alors que la CHP-w effectue la prédiction sur un système thermodynamique fermé qui aspire pour produire la sortie de travail en tant que cible. Le procédé de CHP-w a été mis en place sur les caractéristiques de prise en charge de l'équilibre des fluides de combustion interne de la chaudière avec un niveau de production de vapeur surchauffée élastique, à l'exception du gaz de combustion, évitant ainsi autant que possible l'utilisation directe de la chaleur interne de la chaudière, recueillant la chaleur interne de la chaudière d'une seule main en produisant de la vapeur surchauffée et en ayant été capable de convertir l'enthalpie/la température et l'énergie/pression cinétiques les unes dans les autres par différents types de vapeur dans un système fermé. Le procédé de production d'énergie par CHP-w permet d'obtenir autant de vapeur surchauffée que possible à partir de la chaleur interne de la chaudière, à l'exclusion du gaz de combustion et de produire le travail à partir de celle-ci. Si la vapeur doit être laissée dans le type et la quantité désirés à partir de la génération de travail en extrayant de la sortie de la turbine soit directement en tant que vapeur, soit en utilisant la conversion de celle-ci en énergie thermique est le nom d'un système thermodynamique fermé. En raison de l'utilisation du procédé de CHP-w, les installations de production de panneaux de bois MDF ont en particulier la possibilité de produire de l'énergie électrique à une vitesse très importante avec leurs propres résidus de production de biomasse. Il en va de même pour d'autres installations de fabrication de panneaux à base de bois dont les résidus de biomasse ligneuse découlant de la production ne sont pas aussi importants que pour le procédé de production de MDF. La vitesse de montée en température nécessaire pour produire de la vapeur surchauffée est très faible. Tout le travail effectué par la vapeur surchauffée n'est effectué qu'avec cette petite quantité d'énergie. En même temps, c'est la quantité totale d'énergie qui est perdue par transformation en travail dans un système fermé. C'est le coût de travail. La plus grande partie de la chaleur produite dans la chaudière est utilisée pour l'eau à une température de 104 °C pour la convertir en vapeur saturée. Cependant, cette énergie de chaleur perdue peut être récupérée à nouveau par un type approprié de vapeur dans un système fermé et peut être évaluée de la manière qui est souhaitée, lorsque nécessaire.
