本文研究放大重油喷燃器时燃烧过程的模化法则。文中首先综述了燃烧模化的一般规律,著者认为完全模化是不可能的。其次指出,紊流扩散的准则数R_e保持相等是不合算的。然后,较详细地总结了佛立许的研究而引用了他的模化法则。根据这个法则,放大重油炉时紊流扩散恶化,因而燃烧条件允许的炉膛容积热强度降低。著者还分析了着火过程的模化原理而推导了着火稳定性保持不变的准则。文末附有一例题示出允许炉膛容积热强度的计算。

Distorted PC concentration combustion is a new technology, which was developed for increasing the turning-down ratio of a boiler and decreasing the NO_x emission in flue gas. According to the characteristic of coal combustion, higher PC concentration, temperature and turbulence intensity on the fire-facing side are adopted. Because of fully utilizing the ignition advantage of the firefacing side, the turn-down range of stable combustion without oil was increased. It has been shown by the application that the turn-down range of stable combustion without oil is 54% ̄100% for the coal whose,A ̄y=45% ̄46.95% and V ̄f=14.26%,and NO_x emission was significantly decreased.

变异煤粉浓度燃烧技术是为提高我国电站锅炉调峰能力、降低排烟中NO_x而研究的一种燃烧新技术。它针对煤燃烧的过程和特点,采用了向火侧一次风高煤粉浓度、高温、高湍动度和背火侧低煤粉浓度的水平浓淡燃烧。充分发挥了向火侧一次风的着火优势,使锅炉的着火稳定性和低负荷调峰性能得到了显著的改善。工业应用证明,在燃用A ̄y=45%~46.95%和V ̄f=14.26%的劣质煤时,着火及时,燃烧稳定,锅炉负荷在54%~60%以上不需投油而能稳定燃烧,烟气中NO_x有明显下降,具有显著的经济和社会效益。
