Design ,Construction And Performance Test Of Boiler Water Temperature, Flow Control and Monitoring System.

Abstract

Boiler is the main component in generating steam in thermal power generation units and its control is very important in many applications. In present situation conventional PID control is being used for this purpose. These conventional controllers in power plants are not very stable when there are fluctuations and, in particular, there is an emergency occurring. Continuous processes in power plant and power station are complex systems characterized by nonlinearity, uncertainty and load disturbances. The conventional controllers do not work accurately in a system having nonlinearity in it. So, an intelligent control using fuzzy logic is developed to meet the nonlinearity of the system for accurate control of the boiler steam temperature and water level. The Control system of the industry boiler water level is designed. The control algorithm used normalized PID control algorithm based traditional PID. A normalized parameter setting method is introduced for adjustment of PID parameters. The boiler water level control system is designed based on the Kingview software development platform. The main controller is realized with PLC. The configuration software is used to configure hardware and network. The experimental results prove that the combination of the PLC control system and Kingview configuration software is valuable for design, testing and application. Performance testing was conducted to assess the system's effectiveness in maintaining desired water temperature and flow rates while ensuring energy efficiency and safety
