Title:
FLUID MIXING APPARATUS
Document Type and Number:
Japanese Patent JP3655482
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To lessen the enthalpy deviation at water wall outlet of a boiler firing furnace.
SOLUTION: This mixing apparatus is provided with a plurality of flow-in side communication pipes 4 connected near a lower part water wall pipe outlet connected to a heat transmission pipe outlet of a lower side firing furnace water wall and flow-out side communication pipes 5 connected near an upper part water wall pipe inlet connected to a heat transmission pipe inlet of the upper side firing furnace water wall. In this case, the fluid mixing apparatus 3 comprises a main body formed to be cylindrical and the flow-in side communication pipes and the flow out side communication pipes are radially arranged in the circumference of the main body. The stage interval L1 between the flow-in side communication pipes arranged in a single or a plurality of stages in the fluid mixing main body and the flow-out side communication pipes arranged in a plurality of stages is controlled to be at least 4 times as long as the inner diameter D of the fluid mixing apparatus. Further, the interval L2 between stages of the flow-out side communication pipes arranged in a plurality of stages is controlled to be narrower than the inner diameter D of the fluid mixing apparatus.
