    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).

    摘要： A non-mechanical valve arrangement for use with circulating fluidized bed (CFB) boilers has a CFB reaction chamber and a bubbling fluidized bed (BFB) within an enclosure in the lower portion of the CFB reaction chamber, the BFB containing an in-bed heat exchanger (IBHX). Solids flowing from the BFB enclosure to the CFB reaction chamber may be controlled using one or more non-mechanical valves. Each non-mechanical valve is independently controlled using independently controlled fluidizing means. The non-mechanical valve has collectors to collect solids backsifting into the fluidizing means of the valve. Agglomerates are removed which could block the valve. Channel walls parallel to the direction of solids flow through the valve opening may be provided to reduce external interference with local fluidization to maintain the proper functionality of the non-mechanical valve.

    摘要： A fluidized bed boiler has a heat exchanger with a front wall, a rear wall opposite to the front wall, and two side walls, formed as water tube panels. An inlet opening in a first section of an upper portion of the heat exchanger introduces hot particles from the fluidized bed boiler to the heat exchanger. Heat exchange surfaces for recovering heat from the particles and an outlet opening are arranged in a second section of the upper portion for returning cooled particles as an overflow from the heat exchanger back to the boiler. The heat exchanger further includes a partition wall between the first and the second sections of the upper portion of the heat exchanger. The partition wall extends from the front wall to a center section of the heat exchanger, and is formed by bending water tubes from at least one side wall of the heat exchanger.
