Capture efficiency measurement of local reinforced exhaust system

Popis výsledku v původním jazyce

This report deals with measurement of capture efficiency of the local reinforced exhaust system (REEXS). The constant ? emission tracer gas method is used for quantitative evaluation of capture efficiency. As a tracer gas was used carbon dioxide. Experimental equipment was supplemented by a special local exhaust hood. The local exhaust hood was designed in such way that it can work either as a traditional circular exhaust hood or as a REEXS. A characteristic of the REEXS principle is that the flow patteern may be oriented towards a specific direction, which increases the range of the efficient area significantly. The directional effect is created by radial air inlet along the edge of a flanged circular exhaust opening through a narrow slot. In this report are shown some results of experimental measurements. The measurements were done both for the traditional local exhaust hood and for the REEXS at different ratios between the momentum flow in the inlet and in the exhaust. All measureme
