摘要 针对燃用低质煤的煤粉炉提出采用脉动方式喷入二次风,强化炉内混合与扩散过程,强化燃烧,减小燃烧损失,提高锅炉运行的经济性.并对脉动二次风燃烧方式的实施与对锅炉运行的影响进行了探讨. The pulsating secondary air combustion is put forward aimed at boilers burning inferior pulverized coal in this paper. Strengthening of mixing and diffusing process owing to it may improve combustion efficiency and boiler thermal efficiency . Implementing methods of pulsating secondary air combustion and the influence of it on running of boilers are also discussed.
