Regenerative firing of low calorific value gas for high temperature processes
By applying the self-regenerative burner principle to blast furnace gas (BFG), as well as to combustion air, a burner system capable of high temperature performance at high efficiency can be produced. This allows low calorific value BFG to be used without further enrichment. The design and construction of the double regenerator is described, including computer software and control as well as safety aspects. The various commissioning trials and trials with BFG are discussed and their results assessed. The experimental test equipment was shown to work reliably and efficiently. Four areas have been identified as requiring further work in order to optimise the system prior to commercial exploitation. These are the use of enriched gas/gases containing hydrocarbons, pulse firing, regenerator bed sizing and NO(x) emissions.
