Abstract

The invention discloses a boiler combustion control system, method and device. The control system comprises a combustion treatment device and a control device; the combustion treatment device is used for conducting correction treatment on a boiler control command generated in advance according to obtained currently run digital parameters of a boiler, and a corrected correction control command is obtained; the control device is connected with the combustion treatment device and used for receiving the correction control command and sends the correction control command to an actuator of the boiler, wherein the actuator is used for carrying out the correction control command. According to the boiler combustion control system, method and device, the technical problem that the running performance of an existing boiler which acts based on a DCS is poor is solved.

Description

technical field [0001] The invention relates to the field of boiler combustion control, in particular to a boiler combustion control system, method and device. Background technique [0002] my country's thermal power plants are currently facing increasing pressure. With the continuous increase of domestic power demand, the quality requirements of power generation are becoming more and more stringent, and the frequency and peak regulation of large-scale units are becoming more and more frequent, and the variable load operation puts forward higher requirements for the operation level of the units. During the operation of the boiler, due to the influence of factors such as grid load and fuel type, the actual operating status of the unit equipment is constantly adjusted. In order to save energy, reduce consumption, and reduce pollution in thermal power plants, it is necessary to optimize, adjust and control the combustion and operating parameters of the boiler in real time, suc...
