Abstract
In an all primary combustion burner, a partition plate that demarcates a mixing chamber between the partition plate and a bottom wall section of a burner main body and a distributing plate that sections a space between the partition plate and the combustion plate into a first distributing chamber and a second distributing chamber are provided in the burner main body to cause a fuel gas and a primary air to flow into the mixing chamber A pressure loss is minimized to make it possible to satisfactorily mix the fuel gas and the primary air. An outlet is formed on a downstream side of the partition plate. A guide plate section that extends to the downstream side while inclining in a normal direction, which approaches the bottom wall section of the burner main body, from an edge on the upstream side of the outlet, is provided in the partition plate.
