    Abstract

    A local ventilation solution for mould casting area was designed and dimensioned with the aid of Computational Fluid Dynamic (CFD)-calculations. According to the calculations, the most efficient solution in this case was a push-pull ventilation system. A prototype of the push-pull system was built and tested in actual operation at the foundry. The push flow was generated by a free plane jet that blew across the 9 m wide casting area towards an exhaust hood on the opposite side of the casting lines. The capture efficiency of the prototype was determined by tracer gas method. Also CO and dust concentration measurements were performed. The measured capture efficiencies varied between 43-81 %, depending on the distance between the source and the exhaust. With the aid of the push flow, the average capture efficiency was increased from 43 % (without jet) to 61 %.
