Embodiment
[0087] A comprehensive identification method for the firing conditions of a cement rotary kiln, the system structure diagram, the flow chart of the identification program, and the soft measurement structure diagram of the temperature in the firing zone are as follows: figure 1 , figure 2 and image 3 shown. The comprehensive identification method includes the following steps:
[0088] 1) The rotary kiln firing system is divided into the following sub-links: high-temperature fan link, preheater link, calciner link, kiln link and grate cooler link;
[0089] 2) The main process parameters of the rotary kiln firing system are directly measured by sensors;
[0090] 3) Carry out soft measurement of the firing zone temperature that cannot be obtained directly;
[0091] 4) classifying the real-time data values obtained by step 2) and step 3), and simultaneously determining the variation trend type of the real-time data values;
[0092] 5) According to sub-links, the real-time ...
