Burner fault diagnosis system based on dcs system

Abstract

The invention provides a burner fault diagnosis system based on a DCS (distributed control system). The system is used for monitoring and diagnosing states of a burner and a controller of the burner, and comprises the burner, the controller of the burner, a detecting and measuring device, a solenoid valve with limited feedback, a pump, a fan, and the DCS. The detecting and measuring device is used for detecting fuel conditions and transmitting detecting results to the DCS. The solenoid valve with limited feedback is used for transmitting solenoid valve feedback signals to the DCS. The pump and the fan are used for transmitting states of the pump and the fan in the burner to the DCS. By the aid of the burner fault diagnosis system, the DCS is utilized to diagnose faults of the burner and display fault reasons according to information of the detecting and measuring device, the solenoid valve with limited feedback, the pump, the fan, and the controller of the burner, and the fault diagnosis of the burner can be performed in real time.

Description

technical field [0001] The invention relates to a fault diagnosis system, in particular to a DCS system-based system for fault diagnosis of a burner. Background technique [0002] The burner is a device fueled by light diesel oil, heavy oil, and gas. It has the advantages of high efficiency and low emission. Therefore, the burner is widely used in smelting, drying equipment, industrial boilers, spraying, steam, road construction machinery, and building heating. , Industrial furnaces and other heating equipment. The commonly used burner refers to the oil-gas burner, which is a device that sends oil-gas fuel and air into the furnace according to the specified ratio, speed and mixing method for timely ignition and efficient and clean combustion. [0003] In order to ensure that the burner can work normally, the user must monitor the working status of the burner in real time to understand the working conditions of each part of the burner, especially the stability of the ignitio...

AI Technical Summary

Problems solved by technology

However, at present, most of the burners commonly used in China are imported products, and their control systems are not disclosed to the public. Therefore, users cannot understand the working status of the burner in time. Professionals in various industries such as craftsmen conduct on-site investigation step by step. The maintenance takes a long time and consumes a lot of manpower, material and financial resources. Moreover, it is often impossible to accurately find out the cause of the failure, which affects production.
