摘要： The present invention relates to a method and an apparatus for feeding fuel into a circulating fluidized bed boiler. The invention is specifically concerned on feeding fine, light and/or moist fuel into the boiler. The method and apparatus for feeding light, fine, volatile and/or moist fuel into a circulating fluidized bed boiler is based on collecting circulating bed material to a return flow and introducing the return flow into communication with the fuel being introduced in the furnace (12) so that the bed material return flow and the fuel are mixed together and flow downwards in the furnace (12) for increasing the residence time of the fuel in the furnace (12).

摘要： A circulating fluidized bed reactor comprising a furnace (20), defined by a substantially vertical and planar first wall (12), and a particle separator having a return duct (40) adjacent said first wall. In the lower part of the return duct is arranged a gas seal adjacent a planar tube wall, which wall is said planar wall (12) or a wall (16) defining a space in gas flow connection with the furnace. The width of the horizontal cross section of the lower part of the return duct, measured in the direction of the first wall, is larger than its depth, measured perpendicular to the width. The gas seal includes a seal structure comprising water tubes bent from said tube wall (12, 16).
