GAS CONCENTRATION ESTIMATION DEVICE, GAS CONCENTRATION ESTIMATION METHOD, AND PROGRAM
Document Type and Number:
Japanese Patent JP2023061242
Kind Code:
A
Abstract:
To estimate real-time gas concentrations, from gas concentrations measured with an infrared gas analyzer.SOLUTION: A gas concentration estimation device according to an embodiment of the present invention is a gas concentration estimation device for estimating a gas concentration for controlling a combustion furnace, comprising receiving means of receiving a delayed gas concentration measured value obtained by measuring a concentration of gas discharged from the combustion furnace to a flue using an infrared gas analyzer, and one or more physical quantity measured values obtained by measuring one or more specified physical quantities relating to the combustion furnace each measured by a sensor, and estimation means of calculating an estimated value of the real-time gas concentration measured value as a gas concentration for use in controlling the combustion furnace, from the delayed gas concentration measured value and the one or more physical quantity measured values, using a model for estimating a real-time gas concentration.SELECTED DRAWING: Figure 1
