How to design the cross-sectional area of ??the smoking port of the hotel kitchen exhaust hood for the best effect?

Fuhai’s experience is that first of all, the smoke exhaust pipe should be installed in the middle of the hood to facilitate the extraction of stove fumes under the hood. If there is a steam cabinet under the hood, the joint position between the oil fume exhaust pipe and the hood will be closer to the stove section.

The opening of the air inlet closest to the smoke exhaust pipe opening should be smaller. On the contrary, the air inlet opening farther from the smoke exhaust pipe opening should be larger. This can achieve uniform smoke exhaust, because the farther away from the pipe mouth, the more the air inlet opening is. The closer the suction is, the stronger it is.
