The Steam Boiler Computer Control System Of Research And Application

Industrial boiler is the important thermal power equipment, wide distribution, number, occupy the position play a decisive role in the production. Boiler control system is a complex system, control effect directly affect the energy consumption and output refrigerant boiler quality. At present, there are still a lot of boiler control as the technology behind China’s, lead to instability, fuel production operation of the boiler system utilization rate is low and the discharge of pollutants exceed the standard, restricting the development of enterprises at the same time, but also increased the burden on environment and resources.With the application and popularization of industrial automation, industrial steam boiler control method has put forward higher requirements, which usually has large inertia, nonlinear, time-varying characteristics, the traditional PID control method can not meet those of the resistance furnace control of the production process of high accuracy requirements, must put forward new control strategy to meet the control of steam boiler requirements. In this paper, this paper designed a system based on computer control system of PLC boiler. The system chooses 57-300 PLC as Siemens controller, with the realization of data acquisition and analysis of the site of various sensors, transmitters and other equipment, to achieve the regulation of the system main control loop using the PID algorithm.1 refer to the related literature at home and abroad, and makes clear the meaning and purpose of research on the control system of steam boiler, steam boiler development status at home and abroad are summarized;2 the study of the resistance furnace temperature control algorithm, separately on the PID control, fuzzy control, fuzzy PID control system to carry on the simulation analysis of three kinds of.3 for a project design of large boiler house steam boiler automatic control system project.
