无焰燃烧技术是一种新兴的超低NOX排放燃烧技术,其优点在于:1)能够同时实现CO与NOX的超低污染排放;2)具有宽泛的燃料适应性,可以燃烧包括中低热值富氢燃料在内的多种燃料;3)燃烧稳定,不存在热声振荡与回火等问题.本文设计了一个采用无焰燃烧技术的燃烧室并对该燃烧室在不同工作模式下的动态压力特性进行测试分析.结果说明,无焰燃烧技术能够在达到极低污染排放同时,仍然稳定燃烧,不发生热声振荡,是一种有前途的超低污染燃烧技术.而当燃烧室中存在值班燃料时,在某些工况下会产生热声振荡.
Flameless combustion technology is an emerging ultra-low NOX emission combustion technology with the following advantages: 1) It can achieve ultra-low pollution emissions of CO and NOX at the same time; 2) It has a wide range of fuel adaptability, Hydrogen fuel, etc. 3) The combustion is stable, there is no problem of thermoacoustic oscillation and tempering, etc. In this paper, a combustion chamber with flameless combustion technology is designed and the dynamic pressure of the combustion chamber under different working modes Characteristics were tested and analyzed.The results show that flameless combustion technology can achieve very low pollution emissions at the same time, is still stable combustion, no thermoacoustic oscillations, is a promising ultra-low pollution combustion technology.While there is duty on the combustion chamber In fuel, thermoacoustic oscillations can occur under certain conditions.
