Title:

GAS-AIR MIXING DEVICE FOR COMBUSTION APPARATUS

Document Type and Number:

WIPO Patent Application WO/2013/133578

Kind Code:

A1

Abstract:

The present invention relates to a gas-air mixing device for a combustion apparatus and, particularly, to a gas-air mixing device for a combustion apparatus which effectively controls the amount of gas and air supplied to a burner provided in a combustion apparatus such as a boiler or a hot water heater so as to improve the turn-down ratio, thereby increasing the convenience of using hot water and heating and improving burner reliability. The present invention comprises: a housing having one side coupled to a turbo fan and defining a predetermined space within same for gas and air to flow; an air supplying unit provided on the other side of the housing, and configured of a first air supplying portion and a second air supplying portion which suction air from the outside but supply air through mutually different paths; a gas supplying unit configured of a first gas supplying portion and a second gas supplying portion which supply gas mixed with air suctioned by the air suctioning unit through mutually different paths by means of the turbo fan; and an opening/closing means which closes the second air supplying portion and the second gas supplying portion when a small amount of heat is needed to block the flow of air and gas, and opens the second air supplying portion and the second gas supplying portion when a large amount of heat is needed.
