Coke oven furnace length direction of the fuel gas flow rate distribution measuring method

摘要

PROBLEM TO BE SOLVED: To provide a method of accurately measuring the flow distributions of fuel gas and air in the oven length distribution required for controlling the temperature distribution in a combustion chamber of a coke oven within a proper range.;SOLUTION: The method is provided for measuring the flows of fuel gas and air in a coke oven in which a plurality of combustion chambers each consisting of flues divided plurally in the oven length direction, and a plurality of carbonization chambers are alternately arranged in the oven width direction, for carbonizing coal in the carbonization chambers by burning the fuel gas supplied in each flue with air. A method of measuring the gas flow distribution in the oven direction of the coke oven includes: injecting He gas in the fuel gas or air from the bottom of the flues; analyzing the He gas concentration in the waste gas on the flue outlet side; and measuring the gas flow.;COPYRIGHT: (C)2013,JPO&INPIT
