A two-stage all-fiber single-frequency MOPA is demonstrated. It provides 80W output power with a slope efficiency of 70% at 1064 nm. The phase noise of the fiber amplifiers measured by using multi-dithering technique is less than 50Hz.
The paper presents an updating scheme for ash cooler fluidized air system of a 410 t/h CFB boiler. The ash cooler fluidized air, which is originally designed, is provided by the independent configuration of two forced fans. By analyzing and studying the operating data of the primary air and the ash cooler fluidizing air system at various operating conditions, an optimum scheme is put up that fluidizing...
