Embodiment
[0023] Such as figure 1 , 2 Figure 3 is a schematic diagram of the spherical distributor structure. This embodiment further illustrates the present invention by manufacturing 16 spherical distributors in a 350MW tower gas and oil-fired boiler of Baosteel 4# unit.
[0024] A manufacturing process of a spherical distributor is:
[0025] The first step. Install the pipe joint 4 and the inner long tube 6 inside and outside the top of the upper half of the head 1 with a diameter of 508mm, so that the pipe joint 4 and the inner long pipe 6 are located on the diameter of the upper half of the head 1. 4 The diameter of the inner long pipe 6 is the same, the diameter is 100mm, the pipe joint 4 is 148mm long, and the inner long pipe 6 is 248mm long;
[0026] Step 2. Draw 26 positions to be punched evenly in a circle at the center line of the miter pipe 3 pipe hole 60mm away from the ring seam of the lower part of the head 2 and on each lower part of the head to be drilled The highest point A ...
