Abstract

L'invention concerne l'inflammation directe du charbon pulvérisé dans les chaudières. Elle se rapporte à un procédé d'inflammation et d'entretien de la combustion du charbon pulvérisé dans une zone de combustion, par introduction d'un mélange d'air et de charbon pulvérisé tel que le rapport pondérai de l'air au charbon est inférieur à 1,0 environ avant introduction dans la zone de combustion, les produits chauds de combustion recirculant si bien que l'inflammation provoquée par un arc électrique peut être entretenue et peut stabiliser la flamme. Application à l'allumage des chaudières à charbon pulvérisé.The invention relates to the direct ignition of pulverized coal in boilers. It relates to a process for igniting and maintaining the combustion of pulverized coal in a combustion zone, by introducing a mixture of air and pulverized coal such that the weighted ratio of air to coal is less than about 1.0 before introduction into the combustion zone, the hot combustion products recirculating so that the ignition caused by an electric arc can be sustained and can stabilize the flame. Application to the ignition of pulverized coal boilers.
