Study On The Mathematic Modeling And Simulation Of The Marine Boiler Steam-Water System

Marine boiler, which is complex and has numerous equipment, is an energy switch system. Because of the especial working condition, marine boiler has many characteristics such as small inertia, great dynamic variety, much correlative and restrictive factor between its subsystems etc. So, it is necessary to study the dynamic modeling of marine boiler system.In this dissertation, the structure character of the marine boiler was introduced, the dynamic characteristic of it was analyzed, and a dynamic mathematical model of the boiler steam-water system was established. Based on this model, a simulation model was obtained, and it was used to simulate the working process of the marine boiler. What' s more, using the No. 01 steam power plant, experiments was carried out to study the operating process of the marine boiler. Comparing the simulation curves with experiment curves, we found that they are similar. Therefore, the dynamic mathematical model of the boiler steam-water system and its corresponding simulation model are valid.
