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.

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.

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.
