[0002] Under the current thermal power industry situation, the load adjustment range of generating units is large, and the fuel source is complicated
However, the automatic input rate of the boiler secondary air distribution control system of the coal-fired generating set is generally low, and it is difficult to effectively deal with the combustion problems under complex working conditions in a timely manner. The lagging and unreasonable phenomenon of combustion adjustment is very common. During the operation of the generator set, the coal consumption and nitrogen oxide (NOx) emissions continue to increase, and the hidden dangers of operation safety increase.

The invention provides an online adjusting system and method for secondary air distribution of a boiler. The online adjusting system for secondary air distribution of the boiler comprises a boiler body, a secondary air distribution device, a temperature field monitoring device, a decentralized control system and a secondary air adjusting device. The boiler body comprises a hearth and a plurality of combustors arranged on the hearth in a layered manner in the height direction of the hearth. The secondary air distribution device comprises an air door mechanism used for controlling the secondaryair distribution amount, and the air door mechanism comprises a plurality of air doors; the temperature field monitoring device is configured to monitor temperature field data of the cross section ofthe hearth on line; the decentralized control system is configured to monitor the operation data of the boiler and the opening degree of each air door on line and control the air door mechanism; and the secondary air adjusting device is configured to obtain a control instruction for controlling the air door mechanism by utilizing a prediction model according to the deviation between the temperature field data and/or the operation data and a set value in a real-time state, so that the temperature field data and/or the operation data are/is in a set range. An air distribution mode of secondary air in the width direction, the depth direction and the height direction of the hearth can be optimized.
Description
technical field [0001] The present disclosure relates to the technical field of power plant boiler optimization control, in particular to an online adjustment system and method for boiler secondary air distribution and air distribution. Background technique [0002] Under the current situation of the thermal power industry, the load adjustment range of generator sets is large, and the source of fuel is complicated. However, the automatic input rate of the boiler secondary air distribution control system of the coal-fired generating set is generally low, and it is difficult to effectively deal with the combustion problems under complex working conditions in a timely manner. The phenomenon of lagging and unreasonable combustion adjustment is very common. During the operation of the generator set, the coal consumption and nitrogen oxide (NOx) emissions continue to increase, and the hidden dangers of operation safety increase. [0003] The main reason for this problem is that t...
