Research Of Remote Monitoring And Disposal System Of Boiler

With the continuous acceleration of economic and social development,the demand for energy is also increasing.The gap in energy consumption is widening,making energy conservation and emission reduction become one of the important ways to mitigate the energy crisis.As industrial boilers are important thermal power equipment in china,it is of great significance to improve the operation efficiency of industrial boilers for energy conservation and consumption reduction.China’s industrial boilers are large in number,wide in use and small in average capacity.They are mainly coal-fired,distributed in all walks of life and in all regions.Meanwhile,they are difficult to be centralized managed,with low degree of mechanization and automation.They mostly require manual operation by stoker personnel,but the quality of both management personnel and stoker personnel is not high.All these make boiler operation and management difficult.In this case,this paper puts forward the remote monitoring and disposal system for all kinds of industrial boilers,to realize real-time monitoring of dynamic operation of boiler.Firstly,the framework and workflow of remote monitoring and disposal system for boilers are studied.According to the parameters and signals that must be obtained from the operating conditions of the boiler,the sensor is selected and installed,and the testing sensor of the system is verified.The parameters are measured using qualified instruments and sensors for system testing under the same conditions at the same time,and the results are compared.The results show that the accuracy of system detection sensors and the reliability of data acquisition can meet the reliable collection of boiler operating parameters.After analyzing the demand of the boiler data acquisition,the general data acquisition device is developed by using the industrial microprocessor.The simulation signal detected by the sensor,the switch signal extracted from the main control cabinet of the boiler and the video signal collected by the network camera are collected,followed by aggregating,coding and the data transmission.This device is proved to have strong universality.Secondly,a professional platform software is designed for remote monitoring and disposal system.The parameters such as temperature,pressure,oxygen content and water hardness of the boiler are monitored,collected and stored by sensors and data acquisition devices.Through the network system,they are transmitted to the remote monitoring center,and the software is processed to realize the real-time display,data analysis and feedback control of the boiler operation information.Based on the analysis of operation data and expert system,the monitoring center can realize the remote control of the boiler using modem means of communication.Finally,the whole remote monitoring and disposal system is comprehensively debugged.Through the analysis and simulation of the collected data,the trend of the system simulation is consistent with that of the field measured data.It shows that the real-time data analysis function of the system fully conforms to the actual operating conditions of the boiler,and has the function of guidance for effective operation.Two representative boilers are selected to test under the original operation condition before the energy saving adjustment.After the system analysis,the measures are put forward to adjust the operation of the boiler,including improving the actual operation control conditions and the operation management method.And then the running data under the operation condition before and after adjustment are tested and compared.The results show that the system has an effect on energy saving,especially for coal-fired boilers.The research results show that the remote monitoring and disposal system can effectively supervise the operation of the boiler,find safety problems in time and eliminate potential safety risks.It can also realize the remote operation management,adjust the operation parameters in time,improve the thermal efficiency,and ensure the safe and energy-saving operation of the boiler.At the same time,by expanding the number of boilers,it is expected to establish a regional coverage center for boiler remote monitoring.Information will be shared at all levels,and the real sense dynamic supervision of safety and energy saving of boiler will be achieved,providing reliable basis for the boiler safety and energy saving supervision and policy setting.
