Abstract
(EN)
During operation of a fossil fuel boiler the combustion process results in the deposition in the boiler flues and heat transfer pipes of scale, smut and soot and other solid products which have a serious effect on boiler efficiency. Regular cleaning therefore has to be undertaken in order to maintain a reasonable standard of boiler efficiency and this is both expensive and time consuming. The present invention introduces controlled amounts of ferric oxide (Fe2 O3) the effect of which is to inhibit the deposition of further solid combustion products such as scale, soot and smut and also to alter the character of existing scale, reducing its adhesion and causing the scale to fall away. The effect is to improve boiler efficiency and reduce maintenance costs.

Lors du fonctionnement d'une chaudière à combustible fossile, le processus de combustion provoque le dépôt d'incrustations, de suie et d'autres produits solides dans les conduites de transfert thermique et de gaz d'échappement de la chaudière, ces produits nuisant au rendement de la chaudière. Il est ainsi nécessaire d'effectuer un nettoyage régulier afin de maintenir un niveau standard raisonnable du rendement de la chaudière, ce qui est anti-économique et prend du temps. La présente invention prévoit l'introduction de quantités contrôlées d'oxyde ferrique (FE2O3) dont l'effet est d'inhiber le dépôt d'autres produits de combustion solides tels que de la suie ou des incrustations, et de modifier le caractère des incrustations existantes en réduisant leur adhésion et en provoquant leur détachement. Il est ainsi possible d'améliorer le rendement de la chaudière et de réduire les coûts d'entretien.
