Abstract

A device and method for improving boiler combustion optimization rate belongs to the technical field of boiler electric control operation and maintenance, and comprises a measuring element, a data processing device, a display device, a data communication device, a DCS engineer station and an execution mechanism. An original layer operation control mode of the secondary air door is abandoned and is changed into angle operation control, meanwhile, a control algorithm is optimized, a mathematical model can be established in the data processing device through the device, the optimal secondary air door adjusting condition can be given in time through the genetic algorithm, the boiler combustion efficiency is improved, and the purposes of saving the fire coal amount and the like are achieved. And the method has wide application expansibility.

Description

technical field [0001] The invention belongs to the technical field of boiler electric control operation and maintenance, and in particular relates to a device and method for improving boiler combustion optimization rate. Background technique [0002] With the proposal of the national "double carbon" plan, thermal power units are facing more challenges than in the past. Whether it is the crazy rise of coal prices or the strict grasp of environmental protection indicators, higher requirements have been put forward for the combustion efficiency of boilers. Low combustion efficiency will lead to unqualified nitrogen oxides in the exhausted flue gas, unsatisfactory main steam temperature, and reduced economic efficiency of thermal power plants. However, the traditional DCS (distributed control system) system is difficult to carry out advanced algorithm calculation, and the control situation is poor. DC pulverized coal burners are generally arranged on the four corners of the f...
