ABSTRACT:
An apparatus for supplying a controlled flow of pneumatically transported solid particles, in particular, pulverized coal, comprises a pulverizer or vessel for containing pneumatically suspended solid particles. A supply pipe is connected to the pulverizer or vessel for removing a mixture of pneumatic gas and solid particles from the vessel. A bend is provided in the supply pipe and an aspirator is connected to the supply pipe at a distance of from one to two pipe diameters from the bend. The aspirator is provided on the outer wall of the bend and is supplied with aspirating gas to draw off an amount of mixture from the supply pipe. This controls the amount of remaining flow of mixture through the pipe. The supply of the aspirator is connected to a bypass line which is connected to the mixture inlet of an injector which is supplied with injecting gas. The supply of the injector which carries the mixture is connected back into the vessel. The flow of aspirating and injecting gas is controlled on the basis of flow measurements taken on the supply pipe from the vessel. The aspirator and injector can accurately control the flow of pneumatically suspended solid particles.
