Abstract:

Natural gas is the most dominant fuel to provide process heat in many thermal processing applications, for example in the glass, ceramics or metals industries. However, here as well there is increasing pressure to reduce both fuel costs and carbon dioxide (CO2) emissions. One possible approach in this regard is the use of mostly untreated biogas from fermentation processes as a fuel, either to completely substitute natural gas, or for co-firing. But while the use of such biogas can decrease both natural gas consumption and overall CO2 emissions (biogas is considered to be a CO2-neutral fuel), there is concern how this change of fuel will affect product quality, combustion behavior and the refractory material. Trace contaminations in the biogas are one aspect in this context which might have a negative impact on product quality or the durability of the refractory of industrial furnaces. In the course of a German research project, these topics were investigated both experimentally and numerically for glass melting applications.
