煤粉直接点火装置国内尚未有长期正常运行的经验,其可能存在的问题也尚未充分暴露;本文从点火过程中锅炉设备安全性考虑,提出在升火喷咀上应该装设能够预投和进行伴烧的点火装置,并认为煤粉炉的点火火源应是连续性火焰,有一定的理论根据,本刊希望大家讨论。 Pulverized coal direct ignition device has not had long-term normal operation experience in China, and its possible problems have not yet been fully exposed. In this paper, from the perspective of the safety of boilers in the process of ignition, it is proposed that the preheating nozzle should be equipped with pre- Ignition device with burning, and that the pulverized coal stove ignition source should be a continuous flame, there is a certain theoretical basis, we hope we will discuss.
