Title:
燃焼機器用ガス‐空気混合装置
Document Type and Number:
Japanese Patent JP5828971
Kind Code:
B2
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 for 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 supply part and a second air supply part which suction air from the outside but supply air through mutually different paths; a gas supplying unit configured of a first gas supply part and a second gas supply part 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 supply part and the second gas supply part when a small amount of heat is needed to block the flow of air and gas, and opens the second air supply part and the second gas supply part when a large amount of heat is needed.
