Boiler Operation Energy Efficiency Index Remote Monitoring System

technical field

The utility model relates to a remote monitoring system for boiler operation energy efficiency indicators.

Background technique

Boilers, as the main energy-consuming equipment in my country, consume about two-thirds of the country's raw coal production every year, and their energy efficiency directly affects the energy consumption of industrial boilers. The importance of energy efficiency levels to save energy. At present, while the energy efficiency of boilers is paid attention to, the monitoring of their energy efficiency level has become an inevitable trend. In order to effectively monitor the use of high-energy-consuming boilers and prevent high-energy-consuming Working conditions, it is necessary to develop a dedicated remote monitoring system for the boiler energy efficiency supervision department.

Contents of the invention

The purpose of this utility model is to provide a remote monitoring system for boiler operation energy efficiency indicators with simple system equipment, low cost and convenient maintenance, which can monitor the energy efficiency of the boiler operation in real time and effectively prevent the boiler from exceeding the standard and high energy consumption.

The boiler operation energy efficiency index remote monitoring system of the utility model includes a monitoring station, a central control cabinet and monitoring equipment, the central control cabinet includes a data sending unit, a central processing unit, a data storage unit and a power supply protection unit, and the monitoring equipment includes a carbon content of slag Automatic analyzer, saturated steam humidity monitor, exhaust gas temperature collector, Austenitic analyzer or combustion efficiency tester probe, fly ash carbon content monitor, slag carbon content automatic analyzer installed in the boiler slag remover, The saturated steam humidity monitor is arranged in the main steam pipe of the boiler, and the exhaust gas temperature collector, fly ash carbon content monitor, Austenitic analyzer or combustion efficiency tester probe is arranged in the straight smoke at the outlet of the heating surface of the last stage of the boiler. At the center of the road, the monitoring equipment regularly collects data and connects to the port of the central control cabinet through the data transmission line to transmit the data to the central processor for processing. The central processor first stores the received data and then compares the data with the preset The parameters are compared, and the preset parameters adopt the current boiler energy efficiency monitoring indicators. For the data that does not meet the preset parameter standards, the central processing unit will transmit this set of data to the sending device, and the sending device will pass GPRS network/GSM in the form of GPRS or SMS After receiving the monitoring data, the receiving device of the monitoring station transmits the data to the monitoring terminal through the transmission line.

The boiler operation energy efficiency index remote monitoring system of the utility model can monitor the energy efficiency status of the boiler operation in real time, effectively prevent the boiler from exceeding the standard high energy consumption operation, the system equipment is simple, the cost is low, and the maintenance is easy, and the monitoring data adopts SMS and GPRS. If one method fails to transmit data, another method will be used to transmit data automatically, which can ensure the effective transmission of data. The system can record the energy efficiency level of the boiler in real time. Operating data.
