  • Method for controlling furnace, and analyzing device for carrying out this method
    Patent number: 11885565
    Abstract: To provide a method with which it is possible to ascertain a gas concentration in a furnace rapidly, and to charge an amount of fuel and/or oxygen corresponding to the state within the furnace, and with which it is possible to reduce the device maintenance load. In order to solve the abovementioned problem, this method for analyzing components contained in flue exhaust gas of a furnace includes: a sampling step of collecting a portion of the flue exhaust gas from a flue; a dust removal step of using a centrifugal dust collecting device to separate out dust in the flue exhaust gas collected in the sampling step, to yield an analysis gas; a measuring step of measuring components in the analysis gas to obtain the concentration of carbon monoxide in the analysis gas; and an analysis gas discharging step of causing the analysis gas to be sucked by an ejector.
