摘　　要：介绍了煤粉浓缩器在ＨＧ－６７０／１４０－１２型锅炉上的应用情况。针对采用风扇磨直吹式制粉系统的锅炉，通过冷态模化试验研究，找出了适合于现场应用的煤粉浓缩方式。将冷模试验结果用于实际设备后，取得了良好的效果。实践证明，煤粉浓缩装置能使锅炉在低负荷下断油稳定燃烧。The paper describes the pulverized-coal concentrator application in a HG-670/140-12 type boiler.Cold modelling experiments have been performed to boiler that adopts direct-fired coal pulverizing system with beater wheel mill,an applicable method is put forward to achieve pulverized-coal's concentration.Experiment results are applied in real equipment.Good effects are obtained.It is shown that pulverized-coal concentrating technique enables boiler flameholding even under low-load without oil firing.
