PULVERULENT MATERIAL METERING AND DELIVERY SYSTEM AND METHOD |
摘要 |
<p>A metering and delivery system for feeding finely powdered coal to a combustion chamber includes a hopper containing finely ground coal, a vertical feed pipe extends from the hopper and a horizontal metering conduit is connected to the lower end of the feed pipe so that the coal provides a surface of repose in the metering conduit below an air flow opening. with a bleed opening being downstream of the air flow opening. A venturi jet housing provides suction on the metering conduit drawing ambient air into the openings to entrain coal for injection by an injector lance into a combustion space. Metering of the coal is provided by inversely operated valves through which ambient air flows to the openings in the metering conduit.</p> |
