Investigation into high-temperature corrosion in a large-scale municipal waste-to-energy plant
Resistance to fly ash fluxing hot-corrosion of Ni alloys and aluminised stainless steel alternatives was studied by inserting a probe into a commercial waste-to-energy plant superheater. Novel combinations of ‘forensic’ metallurgy and computational fluid dynamics modelling yielded enhanced understanding of superheater degradation mechanisms, with outcomes validated by the plant operating company. Anti corrosion Surface Engineering of vulnerable plant components is shown to be technically (and commercially) feasible. Expensive nickel alloys can be replaced with coated stainless steel at lower cost. Others researchers are acknowledging the significance of this work, e.g. DOI:10.1016/j.corsci.2011.11.015; DOI:10.1515/revce-2012-0013.
