Abstract:
It is useful for diagnosing coal combustion status and the tuyere and raceway in blast furnace, at the same time, it is supervision running state to study on temperature-field of also helpful for supervising the structure of oxygen and coal burning apparatus, improving coal combustion technology and coal injection operation. The model between red and green information of true color flame image and temperature is established and two dimension raceway section projection temperature-field are achieved by applying no-touch radiation temperature measurement theory and technology. It is proved with experimentation that the method is effective and feasible, and the testing precision can reach 98.09% compared to the testing result of thermocouple of taking out gas.
