So how to optimize the process of coke oven heating control, reduce coke consumption to ensure the stability of coke evenly ripe and extend the service life of coke is still a major problem. This passage is about coke oven heating indepth analysis of bustion process on the basis of the control system in accordance with the requirements of a control system for the overall structure. System uses a Siemens S7300 PLC implement online testing on various parameters (temperature, pressure and flow, etc.), and plete platform configuration which using MCGS process realtime monitoring and control. Because direct measurement on flue temperature is difficult, according to the temperature at the top of regenerator flue temperature it can establish legislation softsensor model to finish an indirect measurement of flue temperature legislation. The control system meets the needs of practical applications, which improving the quality of coke oven coke productivity, reducing energy consumption and extending the life of coke oven, What39。s more, it can reduce environmental pollution in coke production and improve the working conditions This is of great significance. It can create significant economic and social benefits. 內(nèi)蒙 古科技大學(xué)畢業(yè)設(shè)計(jì) 說(shuō)明書（畢業(yè) 論文 ） Key words: coke, soft measurement, MCGS configuration, PLC。 目 錄 摘 要 .........................................................................................................................................I Abstract ......................................................................................................................................
