With prices of conventional fossil fuels such as natural gas and fuel oil projected to remain relatively high in several regions of the world while the global demand for glass production is comparatively low, many glass manufacturers, particularly in Asia and Latin America, are viewing petroleum coke (petcoke) and, secondarily, coal as potentially viable, low-cost, alternative fuels. There are, however, certain challenges and risks associated with solid fuel utilization for glass melting that need to be understood prior to commercial adaptation. And while petcoke / coal combustion may not be an acceptable choice in every case, Air Products' experience and knowhow suggest that enhancement of solid fuel combustion with oxygen will broaden its successful adaptation in glass melting applications relative to the use of air-fuel combustion. This paper explains the challenges and risks of petcoke and coal combustion for glass melting, and via laboratory and field data, highlights the benefit that oxygen enrichment can bring.
