Pressurized fluidized bed combustion with fly ash recycling (PCFBC) technology has been developed at TERI-SEU, Nanjing. 100 hours test was carried out on a 1 MWt heat-input PCFBC facility. A simple special siphon was used for fly ash recycling. The study on combustion performance, alkali vapor formation and NOx emission were conducted with two different kinds of coal and under various operating parameters. Compared to that of conventional PFBC, for PCFBC, combustion efficiency increases in 1--2%, the maximum can reach to 99.8%, NOx emission is reduced by 30%, alkali vapor concentration in flue gas is about 6 ppm.
