Abstract
A venturi tube has a configuration of baffles affixed thereto that serve to greatly reduce the susceptibility of a gas burning appliance to wind gusts. The baffles cooperate to force incoming primary combustion air through a circuitous route before introduction into a flow of gaseous fuel. The circuitous route in combination with the volume of air that is contained within the baffling serves to substantially reduce flame blowout.
Claims8
A venturi tube for introducing primary combustion air into a flow of combustible gas upstream from a point of combustion, comprising:
- a conduit for conducting a flow of combustible gas from a source to a burner having an intake orifice formed therein for admitting combustion air into said flow of gas;
- a first baffle affixed to and about said conduit for blocking a direct path to said orifice;
- and
- a second baffle affixed to and about said conduit for forcing said primary combustion air to take a circuitous route to enter said flow of combustible gas, wherein said baffles are non-concentrically arranged relative one another.
