<p>In an all primary combustion burner, with a longitudinal direction, a latitudinal direction, and a normal direction of a rectangular combustion plate (2) set as an X axis direction, a Y axis direction, and a Z axis direction, respectively, partition plate (5) that demarcates a mixing chamber (4) between the partition plate (5) and a bottom wall section (3a) of a burner main body (3) and a distributing plate (8) that sections a space between the partition plate (5) and the combustion plate (2) into a first distributing chamber (6) on the partition plate (5) side and a second distributing chamber (7) on the combustion plate side (2) are provided in the burner main body (3) to cause a fuel gas and a primary air to flow into the mixing chamber (4) from an upstream side in the X axis direction. A pressure loss is held down as low as possible to make it possible to satisfactorily mix the fuel gas and the primary air. An outlet (5a) wide in the Y axis direction is formed in a portion on a downstream side in the X axis direction of the partition plate (5). A guide plate section (5b) that extends to the downstream side in the X axis direction while inclining the Z axis direction, which approaches the bottom wall section (3a) of the burner main body (3), from an edge on the upstream side in the X axis direction of the outlet (5a) is provided in the partition plate (5).</p> |
