Confirmation of automatic flow control for a gaseous effluent sampling system

Description: The Department of Energy Orders require continuous sampling of potential radionuclide release points to the environment. To achieve continuous isokinetic sampling under fluctuating flow conditions, flow control valves are installed to match the sampling flow rate to the exhaust flow rate. If the flow control valves are not operated properly, sampling is not isokinetic. The system's operating performance can be verified by superimposing the plots of the daily release and sampling volumes. When t… more

Control of fine particulate emissions from coal-fired utility boilers: Spin filter collection device (rotary cyclone)

Description: A bench-scale test program has been performed to evaluate the concept of placing a porous cylindrical surface (such as a metal screen) at the core of a container and spinning the surface with an external motor for fine particulate/gas separation. The rotating surface enhances the centrifugal effects in the annular region and provides a smooth transition between the flow in the annular and core regions and acts like an enhanced cyclone. It is therefore called a rotary cyclone.'' The porous surfa… more
