Venturi Effect Chimney Cap

In fluid dynamics an incompressible fluid s.

Venturi effect chimney cap.

The venturi effect the secret to getting a flue to draw is to have a constriction in the chimney. The vacu stack creates a venturi that causes flue gases to flow up and out of the chimney. This work on the venturi principle and is named after an italian physicist giovanni batista venturi 1746 1822. The streamline flow of the wind around the vacu stack prevents wind from blowing into the chimney even when the wind is deflected downward.

The present invention relates to a chimney with venturi effect 1 used in discharging the waste gases 50 to outside 60 on the configuration using any kind of fuel such as wood coal fuel oil or natural gas for different purposes directing the wind 70 coming from any direction to the chimney inlet 11 therefore comprising directing flap gates 21 and directing flaps 20 improving. I became convinced that a chimney cap designed to create a venturi effect would be the answer to my. This creates the venturi effect at the top of the chimney and can correct your chimney smoke problem. The vac u stack is a round device with stationary vanes which produces a venturi effect thereby creating a vacuum on the inside of the chimney as the wind is blown against.

Usually the most economical solution is to either install rain caps which divert the wind from being blown down the internal flue tiles or by installing a vac u stack. There are no moving parts to bind or malfunction. The venturi effect is the reduction in fluid pressure that results when a fluid flows through a constricted section or choke of a pipe.
