<p>PURPOSE:To reduce the cost of an analyzing instruments and to improve the reliability thereof by detecting the concn. of O2 and CO2 in a waste combustion gas, incorporating the detected concn. values into the specific equation and determining the concn. of N2 and the concn. of H2O by computation. CONSTITUTION:Fuel is burned in a combustion furnace and the waste gas is supplied to an O2 concn. detector and CO2 concn. detector, by which the concns. thereof are detected. The O2 concn. value and CO2 concn. value obtd. by the detectors are substd. into the equation I, the equation II (where (a) and (b) are the values of CO2 and H2 in the waste combustion gas during combustion by the supply of theoretical air amt. for each 1kg of the fuel, m<3>/kg). The concn. of N2 and the concn. of H2O are determined by the arithmetic processing. The concns. of the O2, CO2, N2 and H2O are respectively displayed on a display part. The concns. of the O2 and CO2 in the waste combustion gas are thus detected and the concns. of the N2 and H2O are determined by using such detected values and therefore there is no need for providing an N2 concn. detecting part and H2O concn. detecting part and the cost of the instrument is reduced.</p> |
