Up to now, five sets of P—200 PFBC—CC Commercial Demonstration Power Plant are operating in the world, in which the bituminous coal and lignite are used as fuel and the combustion efficiency can reach higher than 99%. But using lean coal or anthracite as fuel it will not be satisfied for the expected value. So the combustion characteristic of these lower volatile coals must be tested and the methods of solving problem will be supplied. This paper will discuss and analyze some results from tests as follows: The investigation of the burning characteristic for different coals under pressure, The comparison of the combustion efficiency in PFB combustor for different coals, The research results with fly ash circulating technology for lower volatile coals.
