Abstract

The knowledge around the effect of bioenergy on the thermal properties of iron ore sinter is not widely understood. Therefore, the effects of a 30 % biomass hybrid was investigated. Experiments placed samples in thermal environments encapsulating radiant, convective and conductive heating at increas...
