A series of numerical simulations and model experiments were carried out to search the most effective ventilation system which could protect the working space from dusts and odors in a separated refuse disposal facility. Besides the basic ventilation system which introduces the outdoor air from the one side of the working area and exhausts the contaminated air through the opposite side of the refuse stock yard, an air curtain system and a wind-shield plate are installed on the ceiling to separate these two areas. System performance was measured with the newly built facility. The measurement proved that the system needed only additional 3 % of total flow rate to protect the working space from contamination.
