These kind of burners are suitable to operate in metallurgical processes where the operating temperatures are very high. In fact, our blast furnace burners are usually made from Inconel/Hastelloy, materials suitable to resist to severe working conditions.
These burners are usually equipped with a central pilot igniter operating with natural gas or rich gas, which ensures a correct combustion of the gaseous stream fired by burner. Burners are feeding by a low LHV gas coming from process (Coke Oven Gas or similar) and, when not in operation, they are cooled by a nitrogen stream.
No air register is installed in such burners; the burner is provided complete with a central swirler to guarantee a minimum combustion air vorticity.
We could also provide the supply of complete fuel gas skids and control system.
