Title The control of harmful gases near equipment under pressure by means of air curtains
Original title Lokalizacija gazovyh vrednostej u oborudovanija s vnutrennim izbytočnym davlenijem vozdušnymi strujami [in Russian]
Bibliographic information Aug. 1980, No.8, p.11-13.
Abstract One means of improving the atmosphere in production areas is to install air curtains at the outlets of equipment working under pressure and releasing harmful substances. Air curtains can be compared with gate valves regulating the throughput of contaminated air at a pre-set rate. Empirical formulae to determine the efficiency of 3 types of air curtain are given for angles of incidence between curtain air stream and outlet plane of 0 to 90░. Examples of calculations are given.
