Abstract

The invention relates to a rule-based power station boiler combustion coal-saving nitrogen-reducing control method and device. In the technical field of controlling a fire coal thermal power plant set, the rule-based power station boiler combustion coal-saving nitrogen-reducing control method comprises the following steps of finding out an optimal operation manner of controlled parameters in field device operating record, concluding and summarizing the optimal operation manner to form a control rule, and realizing a rule-based control method and a whole set of corresponding controllers in a controller. The invention has the main advantages that the efficiency and the NOx emission of a boiler of a fire coal thermal generator set are taken as control targets; and through a rule-based control method, an optimal operation result is found out under each working condition and a field device is directly controlled through excavation of history data so that an energy-saving consumption-reducing synergism control effect which can not be finished by a conventional method is realized.

Description

technical field [0001] The invention belongs to the technical field of control of coal-fired thermal power plants, and is a control rule based on finding the optimal operation mode from field equipment operation records, summarizing it, and realizing it in the control device. A control method and a set of corresponding control devices. Background technique [0002] At present, with the development and application of coal-fired units, newer requirements are put forward for the depth of control of coal-fired units, such as the control of energy saving and reduction of NOx emissions in coal-fired thermal power plants. The control of these parameters has the characteristics of multi-parameters and complex control models. It is difficult to undertake these tasks with conventional PID control methods, while model-based control methods and neural networks involve high-level human resources and maintenance. difficulty. [0003] The rule-based control method can solve the above pro...
