CIRCULATING FLUIDIZED BED BOILER

摘要

PURPOSE: A circulating fluidized bed boiler is provided to uniformly maintain capture capability of fly-ash particles in a cyclone and to facilitate repair and maintenance of a loop seal. CONSTITUTION: A circulating fluidized bed boiler comprises a cyclone(300), a slope unit(310), a vertical unit(320), a first discharge pipe(330), and a second discharge pipe(500). The lower part of the cyclone has an asymmetric funnel shape and includes the slope unit, the vertical unit, and the first discharge pipe. The slope unit is located in the side of a combustion furnace(100) from the central axis of the cyclone. The vertical unit is located in the opposite side of the combustion furnace side from the central axis of the cyclone. The upper side of the first discharge pipe is connected to the slope unit and the vertical unit. The lower side of the first discharge pipe is connected to a loop seal(400). The second discharge pipe is connected to the loop seal and the combustion furnace. [Reference numerals] (AA) Central axis;
