Abstract

A laboratory coal metering device for the entrainment of pulverized coals is described. The system uses controlled aerodynamic stripping of the powder surface by a carrier gas to effect the coal feed. This device has been used for approximately one year in bench‐scale combustion studies requiring exacting feed rates with very satisfactory results.

Abstract

The center piece of a particle feeder for steady feeding of fine particles at low rates has been modified by sweeping the particles upward into a concentric tube which also serves as the piston support. The new design has demonstrated superior short and long term stabilities of particle feeding rate; moreover, it has significantly extended the operating ranges of the carrier-gas flow rate, particle feeding rate, and particle size and type.
