چکیده
Abstract Oxy-coal combustion with pressurized fluidized beds has recently emerged as a promising carbon capture and storage (CCS) technology for coal-fired power plants. Although large number of energy efficiency analyses have shown that an increase in pressure can further the net plant efficiency, there are few experimental studies oxy-coal conducted on bed combustors/boilers continuous coal feeding. In this study, experiments lignite anthracite were 30 kWth combustor within range 0.1?MPa to 0.4?MPa. The investigation focused elucidation impacts performance, pollutant emissions desulfurization beds. results showed increased rate particles, promoting effect was more significant high rank smaller particle size O2 concentration atmosphere. For both coals, NOx decreased but N2O accounted considerable part nitrogen oxide pollutants under conditions. had insignificant impact SO2 enhanced direct limestone.

Enthalpy Calculation for Pressurized Oxy-coal Combustion
Oxy-fuel combustion is recognized one of the most promising available technologies that zero emission accomplishment may be in the offing. With coal burned under the pressure of 6MPa and oxygenenriched conditions, the high temperature and high pressure gaseous combustion product is composed of 95% CO2 and water-vapor, with the rest of O2, N2 and so on. However, once lauded as classic approach o...
