Oxygen Enhanced NOx Reduction (OENR) Technology for Glass Furnaces

Liquid air energy storage for combined cooling, heating and power : techno-economic performance enhancement through waste heat & cold recovery

“…Hanak et al [172] From an industrial perspective, OEC is a well-established practice in the glass [175], steel, iron [176,177] and cement industries [178]; however this is not the case in WtE plants in which the economic penalties associated with the production of oxygen used to enrich the combustion process, overcome the operative and environmental benefits [179]. Even though oxygen enriched combustion leads to higher thermal efficiencies (and hence to higher electricity generation) of the WtE plants, the electricity required by the Air Separation Unit (ASU) to produce oxygen is more than the extra energy produced by the WtE plant, thus resulting in an overall reduction in power supply capacity [180,181].…”
