METHOD OF CONTROL OF EJECTOR VENTILATION PLANT Russian patent published in 2002 - IPC

Abstract RU 2179244 C2

FIELD: manufacture of fans. SUBSTANCE: method is characterized by the fact that angle of location of coaxially arranged fan and mixing chamber is varied with respect to mine working longitudinal axis both in vertical and horizontal planes. Proposed method provides for regulation of ejector ventilation plant with nonregulated fan and extended zone of variation of aerodynamic parameters in operation with regulated fan. EFFECT: higher efficiency. 1 dwg
