Research on Temperature Control Method of Direct-heated Electric Furnace in Thermal Power Plant Based on Radiant Energy Signal
The traditional temperature control method of electric furnace has some shortcomings,such as poor control stability and slow re-sponse time,which affects the quality of products.Therefore,the research on temperature control method of direct-heated electric furnace in thermal power plant based on radiant energy signal is proposed.Firstly,the radiant energy signal and the combustion rate in the furnace are calculated,and based on this,the radiant energy signal is detected by using the radiant energy information obtained by the flame color radia-tion image processing technology.Secondly,taking the radiant energy signal as the intermediate variable,the temperature change of the direct heating electric furnace is analyzed to obtain the temperature change state;Finally,the PID controller based on fuzzy immune adaptive algo-rithm is adopted to realize the effective control of the temperature of the direct-heated electric furnace in thermal power plant.The experimental results show that the proposed method has good control ability and anti-interference performance,and has high temperature control accuracy and efficiency under the premise of ensuring the stability of electric furnace temperature control.
