摘要： A method and an apparatus in a fluidized bed heat exchanger including a heat exchange chamber having a fluidized bed of solid particles, heat transfer surfaces, an inlet, and an outlet. Particles are fed through the inlet onto the upper surface of the bed of solid particles by a guiding channel. The guiding channel, which extends from above the upper surface of the bed of solid particles to the surface thereof, or to below the surface, passes the solid particles to the restricted area of the surface. The outlet is formed in the area of the guiding channel to remove particles from the area delimited by the guiding channel. Uncooled particles can thus be removed from the heat exchange chamber.

摘要： A centrifugal separator assembly, which is attached to a fluidized bed reactor for separating solid particles from gas exhausted from a reaction chamber of the fluidized bed reactor, includes a vortex chamber. The vortex chamber is in a horizontal direction defined by vertically-extending outer walls formed of planar water tube panels, the inside of the outer walls being at least partly provided with a refractory lining and defining a gas space in the vortex chamber, where at least one vertical gas vortex is established. The separator assembly also includes at least one inlet for introducing gas into the gas space from the reaction chamber, at least one outlet for discharging purified gas from the gas space, and at least one outlet for discharging separated solid particles from the gas space. In the separator assembly, the vertically-extending outer walls of the vortex chamber form at least one corner, with the angle between the sides of the corner exceeding ninety degrees, and the corner being rounded by a refractory lining on the inside of the outer walls. A method of separating solid particles from exhausted gas with a high degree of particle separation is also provided. In the method, which includes providing a separator assembly as described above, exhausted gas in the vortex chamber is brought to hit at least one corner rounded by the refractory lining on the inside of the outer walls, and the angle between the vertically-extending outer walls of the corner exceeds ninety degrees.

摘要： A circulating fluidized bed reactor includes a furnace, defined by a substantially vertical and planar first wall, and a particle separator having a return duct adjacent to the first wall. In the lower part of the return duct is arranged a gas seal adjacent to a planar tube wall, which wall is the planar wall or a wall 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 that includes water tubes bent from the tube wall.

摘要： A fluidized bed reactor includes a furnace defined by side walls, a roof, and a continuous bottom, and has a solid particle bed in the furnace. Vaporizing surfaces form at least two principally vertical chambers. The chambers have a round or polygonal cross section, and extend from the bottom upwards to at least 80% of the height of the furnace. Also, the chambers are spaced away from the side walls of the furnace and are arranged separately within the furnace, for the furnace volume to be free so that the particles move even in the proximity of the chambers.
