VENTILATION EJECTING PLANT Russian patent published in 1995 - IPC

Abstract RU 2027013 C1

FIELD: mining. SUBSTANCE: fan-ejector is located in shell and the remaining part of working sectional area is closed with partition. Dimensions of shell cross-section are determined proceeding from optimal relation between sectional area in zone of full mixing of primary flow and secondary flow ejected over section between fan and shell. Due to this, constant air flow rate is ensured with maximum ejection coefficient. EFFECT: higher efficiency. 1 dwg
