| Abstract: | The facilities and control strategies were determined to meet the special requirements of closed cycle diesel (CCD) system. The feedforward feedback method was used in oxygen replenishment control. Two methods for CO 2 absorption control were discussed. One was to keep the total pressure constant, regulating the water flow to the absorber and controlling the CO 2 absorption rate. The other was to keep the maximum of water flow rate on the condition that the total pressure was changed according to the load variation, and the balance between the CO 2 absorption rate and its generation rate depended on the inherent regulation. The control system proved to have good control effect by simulation with regard to the CCD equipment configuration. The working conditions for monitoring and safety measures of CCD system were discussed. |
