Intelligent monitoring system for temperature of steam boiler of thermal power plant

Abstract

An intelligent monitoring system for the temperature of a steam boiler of a thermal power plant is disclosed by the present invention, and comprises a client interface, the client interface comprises an alarm module, a display module and a power station network server, and the display module comprises a dangerous point wall temperature display module, a thermal parameter display module and a dangerous point service life display module. The power station network server comprises an integrated process model development platform (IMMS), and the integrated process model development platform (IMMS) comprises a network cloud storage module, a parameter write-in module and a data acquisition module. According to the intelligent monitoring system for the temperature of the steam boiler of the thermal power plant, online monitoring and prediction on the metal wall temperature and the pipeline service life of a heating surface can be well realized by using a software system for monitoring unit data based on a thermodynamic system modeling and simulation technology.

Description

technical field [0001] The invention relates to the technical field of temperature monitoring, in particular to an intelligent monitoring system for the furnace temperature of a steam boiler in a thermal power plant. Background technique [0002] Thermal power generation (thermal power, thermoelectricity power generation) is a power generation method that uses the heat energy generated by combustibles during combustion and converts it into electrical energy through a power generation device. China is rich in coal resources. In 1990, coal production was 1.09 billion tons, of which only 12% was used for power generation. Thermal power generation still has great potential. Thermal power generation generally refers to the general term for using the heat generated by the combustion of combustibles to heat water, turning the water into high-temperature, high-pressure steam, and then using the steam to drive a generator to generate electricity. Power plants that use combustibles a...

Problems solved by technology

Boiler temperature monitoring in thermal power stations is also its core component. At present, the temperature monitoring of the heating surface in the furnace mainly consists of direct monitoring inside the furnace and indirect monitoring outside the furnace. The method of estimating the wall temperature has defects and the results are not accurate enough.
