Abstract

The invention discloses a method and device for optimizing the nitrogen oxide emission of a combustor. The method comprises the steps that S1, operating parameters needing to be optimized for low-nitrogen combustion of the combustor are determined; s2, simulating the discharge amount of nitrogen oxide of a combustor through Fluent when different operating parameters are combusted under a rated load; s3, obtaining a response surface equation according to the different operation parameters and the corresponding discharge amounts; and S4, optimizing the operation parameters of the combustor through the response surface equation. According to the method, a design experiment is carried out on simulation through a response surface method, the influence of multiple factors on the emission amountof nitrogen oxide (NOx) of the combustor is considered, and therefore the optimal technological parameters are obtained, and the emission amount of nitrogen oxide (NOx) of the gas combustor can be effectively reduced.

Description

technical field [0001] The invention relates to the field of energy technology, in particular to a method and a device for optimizing the emission of nitrogen oxides from a burner. Background technique [0002] With the continuous increase of national environmental protection efforts, further reducing pollutant emissions has become a problem that burner manufacturers and users have to consider. Affect gas burner nitrogen oxides (NO x ) generation mainly includes multiple factors such as blade swirl angle, air preheating temperature, excess air coefficient, etc. x ) research and improvement is only based on a single factor in a variety of factors, can not reflect the interaction between the two factors on nitrogen oxides (NO x ) emissions and it is not possible to know the effect of each factor on nitrogen oxides (NO x ) significant degree of impact on emissions. Contents of the invention [0003] Embodiments of the present invention provide a method and device for opti...
