Abstract:
The present invention relates to a gas-air mixing device for a combustor, and more specifically to a gas-air mixing device for a combustor which effectively controls the amount of gas and air supplied to a burner provided in a combustor, such as a boiler or a water heater, thus improving the turn-down ratio which leads to increased convenience for using hot water and heat and enhanced durability of the burner. The present invention comprises: a housing, connected on one side to a turbo fan, provided with a space of a predetermined size in the interior thereof so that gas and air can flow therein; a discharge part disposed on one side of the housing and in contact with the turbo fan; first and second air supply parts, provided on the other side of the discharge part and separated by a first partition, for sucking in air from the outside; first and second gas supply parts, separated by a second partition, for supplying gas which mixes with air sucked in from the first and second air supply parts and is discharged via the discharge part; and an opening/closing means for blocking the flow of gas and air by closing the second air supply part and the second gas supply part when in a low-output mode, and for opening the second air supply part and the second gas supply part so that gas and air can flow when in a high-output mode.
