long-running thermal precipitator

A dust-sampling instrument designed by the Mining Research Establishment of Great Britain that operates over periods of up to 8 h and collects only respirable dust that is selected aerodynamically during the sampling process. The respirable fraction is selected by drawing the dust through a horizontal duct elutriator that simulates the acting principle of the human nose and respiratory passages in that the larger and faster-falling particles are caught by the processes of settlement and impingement.
