Automatic control system for industrial coal powder boiler

Abstract

The invention relates to an automatic control system for an industrial coal powder boiler, which is characterized by comprising an industrial computer, a control cabinet, a core controller, an RS signal converter, an intelligent display instrument and a plurality of sensors; the output terminals of the sensors are connected with the input terminal of the intelligent display instrument, the outputterminal of the intelligent display instrument is connected with the input terminal of the RS signal converter, and the output terminal of the RS signal converter is connected with the industrial computer and the control cabinet; the core controller is directly connected with the industrial computer and the control cabinet; and the core controller comprises a water supply controlling unit, a powder supply controlling unit, a pulverized-coal combustion controlling unit and a fly ash collection controlling unit. The invention not only can finish the acquisition of the related technical parameters of the boiler, ensure the normal running of the boiler, and achieve the optimum burning effect, but also can realize the automatic regulation and control of water supply, powder supply, starting andstopping and dust removal and ensure the normal running of the boiler under the condition without being monitored by a person.

Description

technical field [0001] The invention relates to an automatic control system, in particular to an automatic control system for an industrial pulverized coal boiler. Background technique [0002] At present, there are many types of automatic control systems for various industrial boilers in my country, but the existing automatic control systems generally focus on remote control, basic start-stop operations and data display. However, automatic control cannot be realized for the proportioning of combustion conditions such as air volume and pressure, and the problem solving during failure alarms. Therefore, it is imminent to design an automatic control system with simple operation, centralized monitoring and computer-based functions such as data collection, process control, safety alarm and interlock protection in the running process. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide an automatic control system ...
