Patent ID: 8827694

Claim:
A burner device that burns a mixture gas of an oxidant and a fuel, comprising: an oxidant flow passage through which the oxidant flows: a pipe portion that has a hollow interior portion connected to the oxidant flow passage; and a partition member that air-permeably partitions the interior portion of the pipe portion into a take-in passage region of the oxidant, an ignition region that ignites the mixture gas, and a flame retaining region that maintains combustion of the mixture gas, wherein the partition member comprises a center plate having a protrusion portion that protrudes into the oxidant flow passage, and that stops a part of the oxidant flowing through the oxidant flow passage to guide into the take-in passage region, and a side plate that extends from the center plate and partitions the ignition region and the flame retaining region, and wherein a through-hole is formed at a central portion of the center plate, and a part of the oxidant taken into the take-in passage region is supplied directly to the flame retaining region through the through-hole.
