INTEGRATED GASFICATION COMBINED CYCLE

摘要

PURPOSE: A coal gas complex electricity generation system is provided to stably operate by detecting and solving a bridging event. CONSTITUTION: A coal gas complex electricity generation system comprises a gas fire(10); plural hoppers(20); a nitrogen transporting pipe for high pressure transportation(30); a high pressure oxygen transporting pipe(40); a bridging detector and a bridging remover. The bridging detector detects that a fine powdered coal is not easily supplied into the nitrogen transporting pipe by loading the coal on a transferring screw(50). An orifice(60) is installed on the nitrogen transporting pipe(30). A first manometer(70) is installed in the orifice(60). A second manometer(80) is located between the hopper(20) and the gas fire(10) to measure a pressure inside the nitrogen transporting pipe(30) and the gas fire(10). The manometers(70,80) are connected with a computer(90) through a transmitter(91). The bridging remover is selectively operated by the pressure to be measured through the manometers(70,80).
