Experimental analysis of a multi fuel burner for low calorific gases in large scale firing applications

Low calorific value (LCV) gases are often overseen as potential fuel sources in many processing industries. Generally LCV gases formed in many steel making and chemical plants are often used to generate heat and steam for further sub-processes. Yet put into a broader perspective only a small fraction of LCV gases actually contributes to the total generation of process heat in the industrial processing sectors. However the potential to utilize these gases in thermal processing applications is enormous, which is why a few burner and plant manufacturers have started to focus on developing innovative products for these easy to recover fuel sources. For the past few years the Gaswärme-Institut Essen e. V. (GWI) has closely worked together with industrial project partners to investigate this topic in gas and burner technology. In a series of experimental tests GWI and BTS Engineering Erkrath (BTS) have recently demonstrated that a low-emission and safe operation is achievable using a newly developed multi fuel burner for high performance applications.
