Abstract

The aim of the study was to analyze and assess the thermal insulation of three walls (the side wall, the front wall with a hook and the back wall – the door) of a bioreactor for an aerobic biostabilization of waste (built in accordance with the DIN 30722 standard) for 3 different variants of thermal insulation applied. It should be noted that currently there are no requirements in the literature regarding the design of a thermal insulating layer of bioreactors in municipal solid waste treatment installations in Poland. The side wall of the bioreactor and the front wall (with a hook) appeared to have the best thermal insulation while the back wall (the door of the bioreactor) showed the worst insulation. This was confirmed by photographs (thermograms) taken using a thermal imaging camera. The highest observed temperatures were recorded on the door of the bioreactor, on which many thermal bridges were also visible. The lowest mean temperatures on the surface of the bioreactor walls were obtained using foam insulation (variant 1), however, it was found that the differences between the temperatures of the analyzed elements in particular variants were not statistically significant.
