The simulation of influence of different coals on the

The combustion performance of the boiler largely depends on the coal type. Lots of experimental research shows that different fuels have different combustion characteristics. It is obvious that fuel will change the whole operating performance of Circulating Fluidized Bed Combustion (CFBC). We know even in a pilot-scale running boiler, the measurement of some parameters is difficult and costly

What is the Difference Between AFBC and CFBC Boiler-ZBG Boiler

Oct 28, 2016 · In brief, AFBC means Atmospheric Classic Fluidized Bed Combustion (AFBC); CFBC means Atmospheric Circulating Fluidized Bed Combustion (CFBC). Here let's know their differences from these aspects: velocity, heat transfer surface, requirement on size of coal, combustion air supply, and so on. 1.Velocity: AFBC = 1.2 m/sec to 3.7 m/sec.

1 day ago · 1.Introduction. Circulating fluidized bed (CFB) boilers have many advantages over conventional combustion technologies. The most attractive features of CFB boilers, despite the combustion of low-quality coals, are their relatively low NO x emission and effective capturing of sulfur. Low-grade fossils contain a significant amount of minerals, and therefore their ash content is normally …
