CONVERTER GAS COMPONENT SOFT MEASURING METHOD BASED ON GAS HEAT VALUE AND FLUE GAS COMPONENTS

摘要

A converter gas component soft measuring method based on a gas heat value and flue gas components. The method comprises the following steps: acquiring effective data by means of measurement, wherein the effective data comprises a converter gas dry-basis lower heat value and combustion furnace flue gas components, and the combustion furnace flue gas components comprise the volume content percentage of O₂, CO and CO₂ in dry flue gas; and calculating, according to the obtained effective data, the components of converter gas entering a combustion furnace. The present invention overcomes the inconvenience and solves the difficulty brought about to the operation of a combustion furnace due to the fact that currently most steel plants are not equipped with an on-line analyzer for converter gas components entering the combustion furnace, thereby achieving good practical value in engineering. The present invention is further applicable to a combustion furnace heat efficiency performance test, gas components can be distinguished by means of simply using a gas heat value instrument to measure a gas heat value and using a flue gas analyzer to measure flue gas components; moreover, the present invention is further used for combustion furnace performance calculation and analysis, thereby avoiding gas sampling and testing work required by a traditional method, and is particularly applicable to the fast calculation of combustion furnace heat efficiency.
