[0064] Specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings and examples.
[0065] With the method proposed by the present invention for post-combustion CO 2 The improved INA feed-forward control method of the capture system is used to control CO after combustion in a 1MW thermal power unit. 2 Taking the application in the capture system simulation model as an example, the control objective is to keep the temperature of the reboiler at 386K and keep the CO 2 The capture rate tracks the setpoint.
[0066] figure 1 It is a schematic block diagram of the principle of the existing INA control method, and the performance parameters and effects of the existing INA control method are detailed in Table 1 above. In order to overcome the shortcomings of existing INA control methods, figure 2 A schematic block diagram of the principle of the improved INA feedforward control method of the present inventi...
