Title (EN) SULFUR IGNITION PROCESS AND APPARATUS IN A COMBUSTION FURNACE
(FR) PROCÉDÉ ET APPAREIL D'ALLUMAGE DE SOUFRE DANS UN FOUR À COMBUSTION
Abstract:
(EN) Sulfur ignition process in a combustion furnace, which involves feeding the sulfur in the furnace only when the temperature in the furnace input area is higher than that of the sulfur self-ignition; said temperature being preliminarily increased by preheating the combustion air at a temperature higher than that of the sulfur self-ignition. This takes place with a sulfur combustion apparatus comprising at least one pre-heating apparatus installed directly into the sulfur combustion air feeding pipe upstream of the furnace.
(FR) L’invention concerne un procédé d'allumage du soufre dans un four de combustion, impliquant l'alimentation en soufre dans le four uniquement lorsque la température dans la zone d'entrée du four est supérieure à celle de l'auto-allumage du soufre ; ladite température étant préalablement augmentée par préchauffage de l'air de combustion jusqu’à une température supérieure à celle de l'auto-allumage du soufre. Ceci s’effectue au moyen d’un appareil de combustion de soufre comprenant au moins un appareil de préchauffage installé directement dans le tuyau d'alimentation en air de combustion de soufre en amont du four.
