Embodiment Construction

[0038] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0039] see figure 1 , a method for reducing nitrogen oxides produced by boiler combustion, comprising the steps of:

[0040] Step S10: Obtain the proportions of nitrogen oxides, combustible gases and combustion accelerants in the exhaust gas;

[0041] Step S20: According to the theoretical optimal ratio of the flammable gas and the combustion aid, it is judged that the adjustment object...

Abstract

The invention relates to the technical field of boiler combustion control, and provides a method and device for reducing nitrogen oxides produced by boiler combustion. Theoretical optimal ratio of gas and combustion aid, judge the adjustment object is flammable gas or combustion aid; adjust the intake speed of the adjustment object; obtain the ratio of nitrogen oxides, flammable gas and combustion aid in the exhaust flue gas again, and judge the nitrogen Whether the proportion of oxides increases; when the proportion of nitrogen oxides increases, stop adjusting the intake velocity of the adjustment object; adjust the intake velocity of flammable gases or combustion oxidizers in real time, so that the nitrogen oxides in the exhaust flue gas The proportion of the boiler can be reduced to a minimum, which can effectively reduce the emission of nitrogen oxides; each boiler can obtain the best combustion mode in its operating state, and improve the utilization rate of fuel, so it has strong universality.

Description

technical field [0001] The invention relates to the technical field of boiler combustion control, in particular to a method and device for reducing nitrogen oxides produced by boiler combustion. Background technique [0002] Nitrogen oxides (NOx) produced during boiler combustion x , including NO, NO 2 and N 2 O) is a gas that is harmful to the environment and difficult to handle. It is basically considered to be one of the main sources of air pollution. a large proportion of emissions. N in nitrogen oxides 2 O may contribute to the greenhouse effect (e.g. increase in temperature), NO and NO 2 It is considered to be an important cause of ground-level ozone, photochemical smog and acid rain. Therefore, it is an important and arduous task to reduce the content of nitrogen oxides in boiler flue gas, thereby reducing the emission of harmful gases of nitrogen oxides. [0003] According to the formation mechanism of nitrogen oxides, it can be divided into thermal nitrogen o...
