Off-gases generated during steelmaking are to a large extent used as fuels in process units within the plant. The surplus gases are commonly supplied to a plant for combined heat and power production. The main objective of this study has been to techno-economically investigate the feasibility of...

Tumble dryers manufactured today are optimised for their maximum capacity, i.e., 6–8kg of dry load. An average washing load in ordinary households lands at between 2 and 3.5kg dry load, which implies that the drying load is even smaller. The energy efficiency decreases with reduced drying...
