摘要
The invention relates to a method for reducing pollutant emissions, released particularly in the form of pyrolysis products from metal casting cases, used in foundry practices. The aim of the invention is to reduce said emissions at low cost. This aim is achieved, whereby at least one additional combustible substance is added to the metal casting cases. Said substance changes into gaseous form on heating, provided that it is not gaseous, and burns together with the pollutants when leaving the metal casting cases. The additional combustible substance contains at least one organic substance, preferably a wax or an oil, ideally a ketone, an aldehyde, ether or alcohol. It can also be advantageously formed by a combustible gas (natural gas).
