  Abstract Text

  Oxyfuel FBC has been examined in a 100 kW pilot plant operating with flue gas cooling. This technology offers almost all of the advantages of air-fired FBC—emissions such as CO or NOx are lower or comparable to air firing, and it is possible to switch from air firing to oxy firing easily, with oxygen concentrations as high as 60-70% and flue gas recycle levels of 50-60%. Only sulphation is poorer, which is not in good agreement with other studies, and the reasons for this discrepancy need further exploration. However, longer tests have confirmed these findings with two coals and a petroleum coke. It also appears that changing from direct to indirect sulphation with the petroleum coke improves the sulphation, although a similar effect could not be confirmed with coal. « hide
