Jiang, T.; Du, L.; Zhang, L., and Cao, L., 2018. Effect of circulating water temperature change on the dynamic characteristics of ocean ship thermal-system heater. In: Liu, Z.L. and Mi, C. (eds.), Advances in Sustainable Port and Ocean Engineering. Journal of Coastal Research, Special Issue No. 83, pp. 81–85. Coconut Creek (Florida), ISSN 0749-0208.

In this paper, the sections of superheating, condensate and sub-cooling of drain water in a ocean ship thermal-system heater are set as a unit. The heat storage capacity of the heater itself is considered and the sudden change of the circulating water temperature was set as turbulence. A mathematical model was conducted to calculate the outlet temperature of circulating water, the flow rate of extraction steam and the saturation temperature in the ocean ship thermal-system heater. And the changed trends of these parameters are analyzed under the turbulence. Then the dynamic process of heater from the state with turbulence to a new stable state was obtained. Finally, the balancing speed of the other parameters of ocean ship thermal-system heater was analyzed according to the time that the dynamic process took to reach a new stable state.
