Abstract As one of the most important auxiliary systems of a circulating fluidized bed boiler, the limestone pneumatic conveying system is of great significance to its operation. Maldistribution of powder in the different injecting ports seriously limits inner-furnace desulfurization performance owing to inefficient mixing of limestone powder and SO2. The gas–solid flow characteristics of an industrial-scale multiple-branching limestone-conveying pipeline system of a 200 MW circulating fluidized...

Abstract The bed inventory overturn in pant-leg CFB boilers and bed pressure wave in single air distributor CFB boilers were the two well-known non-uniformity problems in large scale CFB boilers. However, a special gas solid flow non-uniformity problem, bed pressure deviation, occurred in a single air distributor 330 MW CFB boiler. The bed pressure in one side was 2 kPa constantly higher than that in the other side and lasted for a long time, resulting to the local over temperature and endangeri...

Abstract While the power plant units are the developing towards larger capacity, the relative shortage in thermal efficiency of the circulating fluidized bed (CFB) boiler unit, which has obtained significant development in recent years, is becoming more and more apparent. However, the thermal efficiency computational model applied for different CFB boiler units are not derived yet. Based on Generalized Energy Efficiency Distribution Matrix (GEEDM) model which is designed for normal pulverized co...
