| High temperature heating furnace is one of the indispensable equipment in the chemical industry and petrochemical industry,and the normal operation of the industry can be guaranteed under the role of the equipment.The process medium is uniformly heated in a high-temperature heating furnace,and a large amount of flue gas radiation is formed during the heating process,generating transfer effects,and these flue gases increase the temperature of the medium.Therefore,the main factor to ensure the uniform heating of the medium in the furnace is the stability of the combustion process temperature and the release temperature.In order to judge the degree of combustion stability,it is usually reflected according to the color and shape of the flame.If the combustion speed is not properly adjusted,or the thermal efficiency is reduced due to poor stability of the combustion process,the failure of these media to be fully burned will produce a large number of pollutants,and the service life of the equipment will be greatly shortened.Therefore,it is necessary to monitor and control the flame combustion state in real time,so that the temperature in the heating furnace forms a fixed temperature field.Manual observation of the main method of monitoring the temperature in the furnace in the past is related to the personal experience of the staff,and it is difficult to monitor at all times,and the accuracy of the monitoring results obtained is low.In the safe application environment of the heating furnace,this paper focuses on the problems of flame imaging characteristics in the heating furnace and real-time monitoring of the temperature field.The research object selected here is the heating furnace,and the method used is CCD colorimetric temperature measurement,which is used to analyze the flame temperature in the furnace,and a flame temperature monitoring system is established on the basis of color CCD.The following briefly introduces the main contents of the research in this paper: firstly,the background environment of the detection flame temperature,the development status at home and abroad,and the research value are described;The imaging characteristics of flame combustion were explored under the premise of safe production,and the colorimetric temperature measurement method was proposed to measure the flame temperature in the furnace.At the same time,the software and hardware system is designed and developed on the color CCD platform,and the hardware components of the system include filters,CCD cameras,computers,image grabbers,etc.In terms of software,select VC++ 6.0 language to develop the monitoring temperature field system page,in which the temperature field single point temperature and the overall temperature can be measured,and the early warning information will be automatically sent after abnormal temperature.By viewing the abnormal temperature coordinate points distributed in the temperature field,you can clarify the location,temperature and other information of the point,and formulate effective solutions for the abnormal temperature point area.Through debugging the software and hardware system function results,the flame temperature monitoring system developed in this paper can meet the requirements of real-time measurement of flame temperature,and the accuracy of the measured results meets the actual requirements.The focus of this paper is to monitor the flame temperature of the furnace in real time,and the actual distribution status of the flame temperature field can be obtained after monitoring,so as to realize the safe operation of the furnace.According to the data,the application effect of this system meets the expected requirements. |
