Embodiment Construction
[0040] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0041] Such as figure 1 As shown, a method for predicting the content of sulfur oxides at the inlet of the desulfurization system based on the measurement of the incoming coal quality includes the following steps:
[0042] Step 1: Record historical data of key parameters;
[0043] First, measure and record flue gas volume flow G and volume concentration of sulfur oxides at the inlet of the desulfurization system through the furnace coal quality measuring device and the sensors installed in the power plant Sulfur content of each pulverizer coal quality C i and coal feed F of coal mill i i historical data.
[0044] Step 2: Construct the steady-state conservation equation of sulfur content;
[0045] The sulfur content information of the coal quality of the pulverizer is obtained through the coal quality measuring device. The sulfur...
