Embodiment 2

[0025] Embodiment 2: as attached figure 1 As shown, the method of using the power plant boiler combustion control device is carried out as follows: use the boiler furnace temperature field sonar test sub-module to collect the temperature data on the boiler furnace section, and use the boiler furnace coal combustion flame spectrum element analysis sub-module Obtain the elemental spectrum analysis data of the combustion flame of the pulverized coal in the burner area of ​​the boiler. Then, the sonar test sub-module of the boiler furnace temperature field sends the temperature data to the boiler combustion automatic warning sub-module, and the combustion flame spectrum element analysis sub-module of the boiler enters the furnace The module sends the element spectrum analysis data to the boiler combustion automatic warning sub-module, and the temperature data is compared with the standard temperature set by the boiler combustion automatic warning sub-module to obtain the temperatur...

Embodiment 3

[0026] Embodiment 3: as attached figure 2As shown, as the optimization of embodiment 2, the use method of the power plant boiler combustion control device is carried out as follows: the sound wave probe of the radar detector is fixedly installed on the water wall of the boiler, and the sound wave probe of the radar detector collects the boiler furnace For the temperature data on the section, the spectrometer is used to collect the light intensity of the pulverized coal combustion flame in the burner area of ​​the boiler. The spectrometer converts the collected light intensity into corresponding flame spectral data, and the spectrometer sends the flame spectral data to the chromatographic comparison instrument. The flame spectrum data is processed by the chromatographic comparator to obtain the element spectrum analysis data. Then, the radar detector sends the collected temperature data to the judgment module, and the temperature data is compared with the standard temperature s...

Abstract

The invention relates to the technical field of control devices for power station boilers and using methods of the control devices, and provides a combustion control device for a power station boiler and a using method of the combustion control device. The combustion control device for the power station boiler comprises a boiler furnace temperature field sonar testing submodule, a boiler as-fired coal combustion flame spectrum element analysis submodule, an automatic boiler combustion early-warning submodule and a thermal generator set operation control module. According to the combustion control method for the power station boiler and the using method of the combustion control device, relevant information of quality changes of as-fired coal in the boiler can be obtained in time so that an operator can adjust boiler combustion correspondingly at the first time according to the relevant information of the quality changes of the as-fired coal in the boiler, combustion deterioration is avoided, coking of the boiler is prevented, the frequency of cleaning for which the load is forced to be reduced or the boiler is forced to be stopped is reduced accordingly, and the non-stop frequency of a thermal generator set is reduced, namely normal power generation of the thermal generator set is guaranteed.

Description

technical field [0001] The invention relates to the technical field of a power plant boiler control device and its use method, and relates to a power plant boiler combustion control device and its use method. Background technique [0002] During the power generation operation of power plant boilers, due to fuel changes, ash and coking in the boiler furnace often occur, which may cause the unit to stop operating in severe cases. In traditional operation management, due to the long time of fuel testing, operators often cannot obtain relevant information on fuel changes in time, so that operators cannot adjust boiler combustion in time, and lose control of the combustion mode as soon as the combustion deteriorates. , After the coking of the boiler is found, it is often irreversible, and it can only be cleaned up by being forced to reduce the load or shut down the boiler. Thereby increasing the non-stop times of the thermal power unit and affecting the normal power generation o...
