Embodiment Construction
[0041] The present invention proposes an optimal control method for flue gas circulating fluidized bed desulfurization. The present invention will be described in detail below in conjunction with the accompanying drawings and specific examples.
[0042] figure 1 It is a schematic diagram of an optimal control method for flue gas circulating fluidized bed desulfurization. The DCS system is respectively connected to the flue gas circulating fluidized bed and the sulfur dioxide optimization control system based on PLC. The optimization system includes: data communication module, sulfur dioxide prediction module, carbon dioxide calculation module and slaked lime control module. Among them, the data communication module exchanges data with the DCS system, the sulfur dioxide prediction module and the carbon dioxide calculation module are respectively connected to the data communication module and the slaked lime control module, and the slaked lime control module is connected to the ...
