Patent ID: 8733085

Claim:
A burner apparatus that combusts an air-fuel mixture of an oxidizing agent and fuel, comprising: a supply flow path having an upstream end and a downstream end in which exhaust gas used as the oxidizing agent flows; a pipe body connected to the supply flow path through a connecting portion positioned between both ends of the supply flow path, and the pipe body having a hollow interior; and a partitioning component that separates the interior of the pipe body, into an exhaust gas flow path in which the oxidizing agent supplied from the supply flow path through the connecting portion flows, an ignition chamber where the air-fuel mixture composed of the oxidizing agent supplied from the exhaust gas flow path and the fuel is ignited, and a combustion holding chamber where combustion of the air-fuel mixture supplied from the ignition chamber is maintained, wherein the pipe body is configured so that high-temperature gas generated by combusting the air-fuel mixture in the combustion holding chamber flows from the combustion holding chamber into the supply flow path through the connecting portion, and the partitioning component is configured to adjust a flow rate of the air-fuel mixture that is supplied from the ignition chamber to the combustion holding chamber.
