Definitions

  • the above-described method may also include the steps of measuring a flow rate of the air supplied to the air plenum and determining, based on the measured flow rate of air, the flow rate of oxygen and fuel required to provide the desired predetermined percentage levels of fuel and oxygen in the nonflammable premix.
  • the method may also include the steps of regulating the supply of oxygen and the supply of fuel entering the air plenum so that the percentage level of oxygen exiting the air plenum is maintained at the predetermined level of oxygen, and so that the percentage level of fuel exiting the air plenum is maintained at the predetermined level of fuel.

Abstract

L'invention concerne un procédé et un système pour renforcer l'alimentation en air de combustion fournie à un brûleur d'un four afin d'en améliorer la productivité et la rentabilité thermique et, par conséquent, pour minimiser les changements de l'indice de combustion nominal du brûleur. On introduit l'oxygène et le combustible dans un plénum d'air en amont de l'ensemble brûleur en quantités contrôlées pour former un prémélange ininflammable de gaz sous pression, dans ledit plénum, formé d'air, de combustible et d'oxygène. Une sortie du plénum d'air communique le prémélange ininflammable de gaz sous pression au brûleur en vue de sa combustion. Ledit prémélange contient un pourcentage prédéterminé d'oxygène ainsi que de combustible.
