THE DETERMINATION OF EMISSIONS OF POLLUTANTS FROM BURNING WASTE OILS

As a consequence of the growing awareness of the need to protect the e nvironment, a study was undertaken to investigate the impact of the us e of recycled waste oils as an industrial fuel in relatively small ind ustrial units. Combustion tests were carried out in a 230 kW experimen tal furnace with oils that had been subjected to pretreatment involvin g centrifugal separation of solids present. However, the analysis of t he combustion gases demonstrated that the levels of principal contamin ants such as lead and other heavy metals were still too high to meet t he emission levels required by the European Union. This suggests that physical processes are inadequate to remove the contaminants present i n waste oils. (C) 1996 Elsevier Science Ltd.
