Abstract

The embodiment of the invention discloses a method of correcting a height coefficient formula of a flame center. Through a numerical simulation, a flue gas temperature of a furnace outlet and height coefficients of the flame center more accurate than those obtained from a traditional thermodynamic calculation can be obtained, an empirical formula of the height coefficients of the flame center in the traditional thermodynamic calculation is taken as a template, numerical fitting is conducted on the height coefficients of a first flame center obtained by the numerical simulation, and a calculation formula of the height coefficients of the flame center more adapted to an existing oxygen-enriched combustion boiler but similar to the traditional empirical formula is obtained. The method is of great significance to the thermodynamic calculation under the condition of oxygen-enriched combustion boiler. The method solves the technical problem that the traditional empirical formula of the height coefficients of the boiler flame center cannot obtain accurate height coefficients of the existing oxygen-enriched combustion boiler center.

Description

technical field [0001] The invention relates to the field of boilers, in particular to a method and device for correcting a flame center height coefficient formula. Background technique [0002] The traditional calculation of the boiler flame center height coefficient is calculated by an empirical formula, but this empirical formula originated from the introduction of foreign technology in the last century, and the empirical formula was summarized from the boiler engineering data at that time. Due to the development of boiler technology today, various design parameters are quite different from those at the beginning, and the traditional empirical formula is no longer suitable for the calculation of the flame center height coefficient of oxygen-enriched combustion boilers. Therefore, it leads to the technical problem that the accurate center height coefficient of the existing oxygen-enriched combustion boiler cannot be obtained through the empirical formula of the traditional...
