In addition to the low emissions of SO2 and NOx, the fuel flexibility of ACFB boilers is extremely wide. Subcritical ACFB boilers with moderate efficiencies are commercial in sizes up to approximately 100 MWe. There are a few plants greater than 100 MWe in operation in the world and some are under construction. In India and China, only small-scale fluidized bed boilers are in operation. The major drawback is that today there are only limited means of utilizing the waste, which means disposal is still necessary.

Inherent moisture contents are unexceptional: typically 8-15%. The coal, which is hard, generally has a low swelling index and low volatile content. Much of the coal has a crushing strength of 200-300 kg/cm3. Compared to other countries only a small part of Indian coal is screened or washed for impurities. Page 8 An unenforced Indian government policy states that coal should be washed whenever the distance between the mine and the end-user is greater than 1,000 kilometers. An attainable and reasonable goal for the washing of Indian raw coal is to reduce the ash content from as high as 50% to at least 30%-40% ash or even down to 25%.
