Definitions

  • burners are advantageously used in heating systems of residential and non-residential buildings.
  • the heat generated by the burner when burning the fuel heats water in a boiler.
  • burners for liquid fuels such as heavy oil, extra light fuel oil or kerosene exist burners exist two basic types, namely on the one hand burners in which the liquid fuel is atomized by means of a nozzle, which are referred to as atomizer, and on the other hand burner in which the liquid fuel is evaporated under heat, which are referred to as evaporator burner.
  • heating boilers have been designed as so-called condensing boiler, in which the exhaust gas is condensed, so that the heat of condensation of the exhaust gas can be used.
  • the boiler temperature is only as high as absolutely necessary. If, for example due to the prevailing weather for the operation of the heating a flow temperature of 30 degrees Celsius is sufficient, the boiler has this temperature.
  • Such a burner is off WO-A1-2004 / 109183 known.

Claims (10)

  1. Procédé pour le pilotage d'un brûleur à vaporisation qui comporte une chambre de vaporisation à chauffage électrique dans laquelle le mazout à brûler est amené et qui comporte un ventilateur pour le transport de l'air de combustion, caractérisé en ce que lorsque le brûleur est en fonctionnement, une valeur courante de température dans la chambre de vaporisation (TVDKIst) est régulée selon une valeur de consigne de température dans la chambre de vaporisation (TVDKSoll) par le fait que le débit d'air amené au brûleur est varié, ce qui est effectué au moyen d'un contrôle d'une vitesse de rotation (D) du ventilateur selon une fonction qui dépend de la valeur courante de température dans la chambre de vaporisation (TVDKIst), en augmentant la vitesse de rotation (D) du ventilateur quand la valeur courante de température dans la chambre de vaporisation (TVDKIst) est supérieure à la valeur de consigne de température dans la chambre de vaporisation (TVDKSoll), et en diminuant la vitesse de rotation (D) du ventilateur quand la valeur courante de température dans la chambre de vaporisation (TVDKIst) est inférieure à la valeur de consigne de température dans la chambre de vaporisation (TVDKSoll).
  2. Procédé selon la revendication 1, caractérisé en ce que la valeur de consigne de température dans la chambre de vaporisation (TVDKSoll) est d'environ 480 °C.
  3. Procédé selon la revendication 1, caractérisé en ce que lorsque le rendement (P) du brûleur est modulable, en cela qu'un rendement thermique (P) peut être modifié entre une valeur à bas régime (Pmin) et un régime nominal (PNenn), la valeur de consigne de température dans la chambre de vaporisation (TVDKSoll) est modifiée suivant une fonction qui dépend du rendement thermique (P).
  4. Procédé selon la revendication 3, caractérisé en ce que la valeur à bas régime (Pmin) est associée à une valeur de consigne de température dans la chambre de vaporisation (TVDKSollmin) et le régime nominal (PNenn) à une valeur de consigne de température dans la chambre de vaporisation (TVDKSollNenn) et en ce que lorsque le brûleur fonctionne à un rendement (P) compris entre ces limites, la valeur de consigne de température dans la chambre de vaporisation (TVDKSoll) associée au rendement (P) correspondant est déterminée par interpolation.
  5. Procédé selon la revendication 4, caractérisé en ce que la valeur de consigne de température dans la chambre de vaporisation (TVDKSollmin) associée à la valeur à bas régime (Pmin) est d'environ 450 °C et la valeur de consigne de température dans la chambre de vaporisation (TVDKSollNenn) associée au régime nominal (PNenn) est d'environ 500 °C.
  6. Procédé selon une des revendications 1 à 5, caractérisé en ce que la régulation est effectuée selon un algorithme de régulation PI.
  7. Procédé selon une des revendications 1 à 5, caractérisé en ce que la régulation est effectuée selon un algorithme de régulation PID.
  8. Procédé selon une des revendications 1 à 7, caractérisé en ce que si, après le démarrage du brûleur, la valeur courante de température dans la chambre de vaporisation (TVDKIst) n'atteint pas la valeur de consigne de température dans la chambre de vaporisation (TVDKSoll), la régulation de la valeur courante de température dans la chambre de vaporisation (TVDKIst) est activée à un moment (t4) de façon forcée par le fait que la vitesse de rotation (D) du ventilateur et ainsi le débit d'air sont réduits jusqu'à ce que la valeur courante de température dans la chambre de vaporisation (TVDKIst) atteigne la valeur de consigne de température dans la chambre de vaporisation (TVDKSoll).
  9. Procédé selon une des revendications 1 à 7, caractérisé en ce que la régulation de la valeur courante de température dans la chambre de vaporisation (TVDKIst) commence après l'écoulement d'un intervalle de temps fixe Δt à partir d'un moment (t2) où le chauffage électrique de la chambre de vaporisation est éteint.
  10. Procédé selon une des revendications 1 à 7, caractérisé en ce que lors d'un changement du rendement thermique (P) et du changement de la valeur de consigne de température dans la chambre de vaporisation (TVDKSoll) qui s'ensuit, le changement d'une première valeur de consigne de température dans la chambre de vaporisation (TVDKSoll1) à une deuxième valeur de consigne de température dans la chambre de vaporisation (TVDKSoll2) s'effectue de telle manière qu'une adaptation en continu de la valeur de consigne de température dans la chambre de vaporisation (TVDKSoll) a lieu pendant un temps de transition (tÜ).
