三功能燃烧器是在偏置射流预燃室的基础上发展起来的一种新型煤粉燃烧器。它是利用一次风射流、控制射流和整流射流组合的空气动力学原理研制的，具有锅炉冷态点火启动、低负荷稳定火焰和作主燃烧器运行三项功能。该燃烧器可利用锅炉原有的供粉系统和一次风管道，并能在运行中方便地转换稳焰和主燃烧器功能，及调节着火点的距离。试验和运行表明，该燃烧器完全能够满足锅炉调峰的要求。具有重要的实用价值和显著的节油效果。
Tri-functional burner is a new type of pulverized coal burner developed on the basis of biased jet pre-combustion chamber. It is developed using the aerodynamic principle of a primary jet, a controlled jet and a rectified jet with three functions: a cold start of the boiler, a low-load stable flame and a main burner operation. The burner can use the original boiler powder supply system and the primary air duct, and can be easily converted in operation stable flame and the main burner function, and adjust the ignition point distance. Test and operation show that the burner can fully meet the requirements of boiler peak shaving. Has important practical value and significant fuel economy.
