Abstract
The present invention relates to a combustion apparatus capable of reducing the emission amount of nitrogen oxide and enabling stable combustion in the entire area of a set load. The combustion apparatus includes: a premixing chamber for premixing air and a gas; a blower for supplying a mixed-gas of the air and the gas to a burner; a combustion chamber for burning the mixed-gas by ignition of the burner; a heat exchanger for exchanging heat with water by using combustion heat in the combustion chamber; and an exhaust gas discharge part for discharging the exhaust gas passing through the heat exchanger, wherein the premixing chamber is formed in a Venturi shape having a throat part of which the cross-section area is tapered between an inlet and an outlet through which the air passes, the throat part of the premixing chamber being connected to a gas supply part for supplying a gas for combustion, and to an exhaust gas recirculation tube to which some of the exhaust gas having passed through the heat exchanger is introduced in proportion to differential pressure according to the flow rate of the mixed-gas passing through the throat part.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
