method and system of ignition sulfur in combustion furnace

摘要

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.
