In the past, there were silent nozzles that resembled an inverted bowl and produced no noise. Look for relevant design institutes.
LZ: Water is heated using steam – why is a steam ejector needed? When steam is introduced directly into water, noise is generated due to bubbling and impact. But if you use the small-hole injection method to heat the water in the tank, the noise can be **reduced**. The specific method is as follows: The steam inlet pipe is buried below the liquid level, parallel to the bottom of the water tank; its ends are sealed, and small holes (3 mm in diameter) are made at angles of 120 degrees on both sides, below the horizontal section of the steam pipe that is submerged in the liquid. The total area of these holes should be 1.25–1.3 times the cross-sectional area of the steam pipe. Why don’t you give it a try? ! For reference.
Thank you! Why are small holes (3 mm in size) made at an angle of 120 degrees below it, on both sides? The total area of these holes is 1.25–1.3 times the cross-sectional area of the steam pipe
Small-hole injection, with the total hole area being 1.25–1.3 times the cross-sectional area of the steam pipe, can also serve to reduce noise； On either side of the 120-degree angle below is an angle of 60 degrees to the left and right along the Y-axis; if the area of the openings meets the requirements, it is also possible to arrange the openings in a single row downward, with the aim of ensuring even distribution of the steam.
We have 5mm holes evenly distributed around the circumference, with an area roughly equal to that of the steam pipe’s cross-sectional area; however, users report loud noise
