Definitions

  • the combustion process of a solid fuel such as wood comprises four phases. At a relatively low temperature of about 100°C the wood begins to dry through evaporation of the moisture still present therein. At higher temperatures of about 150 to 350°C degassing or pyrolysis of the wood then occurs. The chemical structure of the wood is herein broken down with formation of volatile compounds such as CO, H 2 O, CH 4 and lower hydrocarbons as well as tar-like components which are volatile at decomposition temperature but which condense at lower temperature. When the temperature is increased still further to about 550°C and oxygen is added the volatile compounds resulting from the pyrolysis burn. The remaining solid component consists of almost pure carbon and burns at a temperature of roughly 800°C when oxygen is added.

  9. Procédé d'utilisation du dispositif de combustion tel que stipulé dans la revendication 1 pour épurer des produits créés pendant un processus de combustion, comprenant les étapes consistant à mélanger de l'air aux produits de combustion et à éliminer par une post-combustion les restes de substances nocives encore présentes dans les produits de combustion, caractérisé en ce que le processus de combustion, après son démarrage, est entretenu uniquement par l'air de post-combustion.
  10. Procédé tel que stipulé dans la revendication 9, caractérisé en ce que l'air est chauffé avant d'être mélangé aux produits de combustion.
  11. Procédé tel que stipulé dans la revendication 10, caractérisé en ce que l'air est chauffé par la chaleur dégagée pendant le processus de combustion.
  12. Procédé tel que stipulé dans l'une quelconque des revendications 9 à 11, caractérisé en ce que l'air est mélangé aux produits de combustion à contre-courant.
