摘要： Bed temperature in a circulating fluidized bed (CFB) reactor is controlled by varying a recirculation rate of particles collected by a secondary particle separator back to the CFB reactor. Particle storage means, sized to contain sufficient inventory required for bed inventory/temperature control due to fuel/sorbent variations and/or load changes, stores particles collected by the secondary particle separator. The storage means can be either directly below the secondary particle separator or at a remote location. Particles collected by the secondary particle separator rather than by the primary particle separator are preferred due to their smaller size and lower temperature. A bed temperature control system controls the recirculation rate of these particles back to the reactor. Level sensing devices are provided on the storage means. A solids storage level control system that interacts with the bed temperature control system controls the solids inventory in the storage means via a purge system.

摘要： Apparatus for separating solids from flue gas in a circulating fluidized bed (CFB) boiler includes plural vertical, impact type particle separators made of cooling tubes located within the CFB in a plurality of staggered rows. One embodiment employs a plurality of stacked, slip fit elements having apertures which accept the cooling tubes. The slip fit elements cooperate with one another to form a collecting channel, typically U-shaped, which separates particles from flue gases conveyed across the particle separators. Shiplap joints in between the individual slip fit elements prevent gas and solids from leaking therebetween and allow for thermal expansion. Alternatively, the impact type particle separators include cooling tubes connected to one another to form a unitary structure. Pin studs welded to the cooling tubes and covered with a coating of refractory; ceramic tiles; metal or ceramic spray coatings; metal or ceramic castings; weld overlay; and/or shields provide erosion resistance.

摘要： Apparatus for separating solids from flue gas in a circulating fluidized bed (CFB) boiler comprises plural vertical, impact type particle separators located within the CFB in a plurality of staggered rows. The impact type particle separators employ hung elements supported from fluid-cooled tubes which form a collecting channel, typically U-shaped, which separates particles from flue gases conveyed across the particle separators. By separating the support function from the collection shape required by functional performance considerations, the strength requirements of the material used to form the collection shape are reduced and the strength of the material from which the fluid-cooled support is made is much higher due to the lower operating temperature of the material comprising the fluid-cooled support, thereby permitting the use of lower cost materials.

摘要： A tri-sector regenerative oxidant preheater apparatus, method and arrangement for utilization with oxy-fired pulverized coal combustion power plants. The preheater includes a stationary housing and a rotor rotatably mounted in the housing. Sector plates are located at the axial ends of the rotor and divide the preheater into a flue gas sector, two primary oxidant sectors, and a secondary oxidant sector interposed between the two primary oxidant sectors. A primary oxidant fan is located downstream of the preheater to create a negative environment in the primary oxidant sectors. During operation of the preheater, the environments of the two primary oxidant sectors and the flue gas sector are at about the same negative pressure, and thus there is very limited leakage between the oxidant side and the flue gas side of the preheater. The environment of the secondary oxidant sector is at a positive pressure and leakage to the negative environment of the primary oxidant sectors will be that of secondary oxidant to primary oxidant with no loss secondary oxidant to the gas side of the preheater.
摘要翻译：一种采用三氧化二氧化碳燃烧发电厂的三段再生氧化剂预热装置，利用方法和装置。预热器包括固定壳体和可旋转地安装在壳体中的转子。扇形板位于转子的轴向端部，并将预热器分成烟道气体扇区，两个主氧化剂扇区，以及介于两个主氧化剂扇区之间的次氧化剂扇区。主氧化剂风扇位于预热器的下游，以在主要氧化剂部分中产生负面环境。在预热器的运行期间，两个主要氧化剂部分和烟道部分的环境处于大致相同的负压，因此在预热器的氧化剂侧和烟气侧之间的泄漏非常有限。次级氧化剂部分的环境处于正压力，并且主要氧化剂部分的负环境的泄漏将是初级氧化剂的二次氧化剂，而对于预热器的气体侧没有损失的二次氧化剂。

摘要： A circulating fluidized bed (CFB) boiler comprising a reaction chamber. A bubbling fluidized bed (BFB) is contained within an enclosure within the lower portion of the reaction chamber and contains an in-bed heat exchanger (IBHX) that occupies part of the reaction chamber floor. At least one non-mechanical valve, which includes an opening between the CFB and BFB and independently controlled fluidizing means located both upstream and downstream of the opening, is used to control the heat transfer to the IBHX by controlling the solids discharge from the BFB to the CFB. The elevation of the bottom of the opening is at or above the elevation of the fluidizing means. A flow control barrier may be located downstream of the opening.

摘要： A circulating fluidized bed (CFB) boiler includes a reaction chamber, where a bubbling fluidized bed (BFB) is contained within an enclosure within the lower portion of the reaction chamber and contains an in-bed heat exchanger (IBHX) that occupies part of the reaction chamber floor. A plurality of in-bed secondary air nozzles comprise a plurality of tubes which are grouped together and run across the width of the BFB between the BFB enclosure wall and an outside wall of the CFB. The nozzles are positioned to prevent the deflection of solids falling onto the BFB from the CFB by the secondary air jets while avoiding a complicated structure that would interfere with gas and/or solids movement in the furnace. The nozzles' exit openings are flush, or almost flush, with the BFB enclosure wall.
