Design And Application Of Marine Boiler Electrical Control

Marine auxiliary boiler is the special equipment in shipbuilding industry of China and the world, it is the basis of mechanical major equipment manufacturing industry which has been the key development of the national. It has a large influence on the development of the national economy. Starting from the electrical control of Marine auxiliary boiler in this paper, it introduces the basic principle of the electrical design; Several important parameters, including water level, steam control, from the PID simulation to the simulation output, all of these passed the test of theory to practice; All electrical components selection, from different function to different models, lists the components in the project list. The design of the program, Including a large number of digital quantity control, and water level, steam pressure, exhaust gas temperature and other analog control, from the logical function of each control link graph to exhaust gas temperature dry boiled alarm; Safety protection system, safety interlock of each boiler stop alarm, the intelligent and integrity of the program. This paper describes the importance of above electrical design in the whole Marine auxiliary boiler in detail. This article aim at the control object which is the Marine auxiliary boiler with nonlinear, difficult to establish accurate mathematical model, through a series of design and simulation experiment, it is concluded the electrical control plan which meets the requirements of the actual working condition of boiler running, also be used in the bulk of the Marine auxiliary boiler control, the boiler control system is stable and reliable in the bad environment on the sea, control index has reached the Marine standards. It has the value of reference on the basis of Marine auxiliary boiler electrical control design and application.
