SYSTEM FOR MEASURING COAL-POWDER FUEL CONSUMPTION DURING FEEDING TO BLAST FURNACE TUYERES

WIPO Patent Application WO/1991/009142

A1

A system for measuring coal-powder fuel consumption during feeding to the tuyeres of a blast furnace comprises a transportation air flowmeter (5) and a pressure indicator (6) both mounted in a pipeline before the feeding reservoir (1). A pressure indicator (7) is mounted at the end of the pipeline (2) near the tuyeres (3) of the blast furnace (4). The system further comprises a first and a second adders (10, 11), gauging devices (8, 9), a functional converter (12) and a display device (13). The indicators (6, 7) are connected to the second adder (11) which is connected, through the gauging device (9), to the first adder (10). The output of the first adder (10) is connected to the display device (13). The flowmeter (5) is connected, through the gauging device (9) and the functional converter (12), to the first adder (10).
