What is the function of the water seal groove at the lower part of the water wall?

Haven’t seen a design like this before~ It would be great if LZ had pictures

First, it serves to provide sealing and prevent air leakage from the furnace chamber. Second, it serves to cool the slag.

May I see it? Learn* it a bit.

The function of the water seal groove is to maintain tightness at the junction between the moving and stationary parts in the lower part of the furnace, preventing air from leaking in. The water wall is suspended from the top of the furnace, and its length expands and contracts with changes in temperature. The ash hopper located below it is fixed, while the relative position between the ash hopper and the lower header of the water wall will change. During operation, it is required that there be a gap between them to ensure downward expansion of the water wall, while also preventing cold air from leaking in through that gap. The water seal tank is installed at the top of the ash hopper, and steel plates are arranged along the length beneath the lower header of the water wall, with these plates inserted into the water in the water seal tank. The steel plate moves up and down with the lower header, but it never leaves the water surface; this ensures, on one hand, free expansion and contraction of the water wall, and on the other hand, good sealing during such expansion and contraction

Oh! I see. I’ve learned it, thank you!
