CIRCULATING FLUIDIZED BED REACTION FURNACE WITH FIRST INNER PARTICLE ISOLATOR FORMED WITH BOTTOM PART

摘要

PURPOSE: A circulating fluidized bed reaction furnace with a first inner particle isolator formed with a bottom part is provided to simplify the structure of a circulation flowing reaction furnace or a combustion chamber at a low cost by returning all solids collected at the bottom part and omitting a hollow element or a hopper. CONSTITUTION: A circulating fluidized bed reaction furnace with a first inner particle isolator formed with a bottom part includes a reaction furnace section(20) formed with a collision type particle isolator for isolating solid particles from flue gas/solid substances flowing the sections and an outlet opening part(40), crossed collision type particle isolators(140) having a first group of crossed collision type particle isolators(130) positioned at an upper part of the outlet opening part in two rows with relation to the flue gas/solid substances, and a second group of crossed collision type particle isolators(160) positioned at a lower part, and a bottom part(180) positioned below the second group of the particle isolators.
