。In a conventional once-through boiler with a vertical Ia% type furnace, in order to adjust the flow rate through the tube according to the heat load on the tube, it is necessary to take a considerable pressure loss at the furnace inlet, and several tubes are required. In order to provide one flow rate and one throttle device for the combined flow rate, a complicated configuration was required, combining an evaporation pipe, a distribution pipe stopper, a distribution pipe, and a distribution manifold.

る。The present invention aims to provide a flow distribution device with a simple structure and easy maintenance and inspection, as described above, in which the furnace λF-1 header of a boiler is communicated with the furnace tube through an orifice piece and a pipher gate. It is characterized by
従って火炉入日管、寄せから火炉チューブまでか一体的
な管溶接構造となり、装置が軽量化され配置スペースも
縮小化される。Therefore, an integral tube welding structure is provided from the furnace inlet tube and the joint to the furnace tube, which reduces the weight of the device and the space required for its installation.
また、点検も外部より非破壊検査により行なうことかで
き、管寄せのハンドホールが不要となる。Additionally, inspection can be performed from the outside using non-destructive testing, eliminating the need for hand holes in the header.

いる。Boiler water is supplied from the furnace inlet header J to the furnace tube 19 via the liaison 16, the orifice piece 12, the liaison 917, the pipe 14, the pipe 18, and the pipes 1 and 15. In the orifice piece 12, a pressure loss is created by the difference between the inner diameter A of the constricted portion 13 and the inner diameter B of its rear stream, and a difference in flow rate distribution to each furnace tube is created.
またオリフィスピース１２を通過する流量は火炉チュー

ツクできる。Therefore, the 11th Null II has almost the same flow distribution characteristics as the conventional system, but the orifice piece and the double nozzle pipe have the same flow distribution characteristics.
Welded tube integration (14 structures) can be achieved with a simple device without taking up much space.It also eliminates the need for visual inspection of mechanical equipment during periodic inspections. Easily check for wear, corrosion, thinning, etc. of the orifice constriction through non-destructive testing such as external radiation testing and ultrasonic flaw detection.
I can pick it up.
