Design And Implementation Of Package Steam Boiler System

The package steam boiler system has a more complex control circuit, characterized by strong nonlinearity, large delay, multi-coupling, strong interference, simple PID control algorithm is very difficult to make a complex and changing dynamic processa chieve the desired control effect Moreover difficult to achieve a higher run automatically put into use. Current situation and prospects for the development of the steam boiler control system in the world, and has long been the scene experimental analysis, and in-depth study of the advanced control of the steam boiler, from practice to perfection and transformation of the original system, the gas-fired steam boiler system improved combustion efficiency, the excellent quality of adjustment, not only has a certain value of academic research, and has made considerable economic benefits and operability.In this paper, the design and implementation of cnooc’package steam boiler system, for example, the analysis of a steam boiler ignition sequence control, feedwater control, combustion control systems, control programs. Analysis of double-cross control system, and three impulses control system. The typical boiler commissioning and use of the process analysis and proposed solutions. Combined with the fast pot and steam pipe network system in the ammonia plant, proposed improvements and the implementation of programs of its control strategy. Gas-fired steam boiler combustion control system, interlock control system, as well as the entire steam pipe network system are very complex systems, these systems optimize the transformation of control, can significantly improve fuel combustion sufficiency, reduce the cost of production, to ensure safe reliable and efficient operation of steam boilers and steam pipe network. For steam boiler system startup routine maintenance, troubleshooting guide. New system development and upgrading of the existing system of the steam boiler control system.
