Abstract

The invention discloses a combustion optimization method based on CO online monitoring. The method comprises the steps that the concentration of nitrogen oxides at an inlet of a denitration system of a boiler is obtained, the CO concentration of a hearth based on a plurality of CO detection points in the hearth of the boiler is obtained, the operation oxygen amount and the over fire air amount of the boiler are obtained based on the CO concentration of the hearth and the concentration of the nitrogen oxides, therefore, under the condition that the cost is not increased, serious high-temperature corrosion of the boiler is avoided, the treatment pressure of the denitration system of the boiler is reduced, and the service life of the boiler is prolonged.

Description

technical field [0001] The invention relates to the technical field of thermal power generation, in particular to a combustion optimization method based on CO online monitoring. Background technique [0002] At this stage, thermal power generation is still the main source of electricity generation in my country. With the continuous improvement of national environmental protection requirements, the control of the concentration of nitrogen oxides in thermal power plant emissions is becoming more and more intensive. Existing thermal power plants will introduce SCR denitrification system, while reducing the concentration of nitrogen oxides in the discharge, it also increases the cost. At the same time, the high-temperature corrosion phenomenon of the thermal power plant boiler is also a technical problem that the thermal power plant has to solve. The high-temperature corrosion of the boiler is mainly related to the CO and H in the furnace. 2 It is related to the concentration of ...
