【発明の名称】流動床冷却器、流動床燃焼反応器および該反応器の操作法
Document Type and Number:
Japanese Patent JP2818236
Kind Code:
B2
Abstract:
A fluid-bed combustion reactor (51) comprising a substantially vertical reactor chamber with a first inlet (9) at the reactor chamber lower portion (52) for the introduction of liquid and/or solid particulate material, and a second inlet (22) at a level below the first inlet for the introduction of gas for fluidization of particulate material within the reactor in order to maintain a primary fluid bed, an exhaust duct (28) at the reactor chamber upper portion for the withdrawal of exhaust gas and particles from the reactor, and a fluid-bed cooler (42) for particulate material, formed as an upwards open vessel with generally closed bottom and side walls and arranged so as to collect a portion of particulate material (64, 65) from the reactor chamber upper portion, said cooler comprising heat transfer means (43) such as tubes carrying a heat transfer medium at the inside and having said particulate material flowing at the outside, said cooler comprising at least one conduit (56) for the controlled returning of particulate material from the cooler to the primary fluid bed, and said cooler having inlets at the bottom wall (68) for introduction of gas for fluidization of particulate material. The heat transfer means are divided into at least two sections, and the inlets for fluidization gas are divided into sections corresponding with the heat transfer means sections and provided with separate control means for the inflow of fluidization gas into each section.
