たことを特徴とする強制燃焼器。 A burner port plate that blows out a premixture of fuel gas and primary air supplied from an air supply fan from a large number of burner ports, and a secondary air blowout plate and a screen plate that have a large number of air blowholes are connected to a burner port. The secondary air blowing plate includes a combustion chamber formed on the side of the plate, and a secondary air chamber formed to surround the combustion chamber and into which secondary air from an air supply fan flows. A flame holding plate approximately at the height of the inner flame is installed at the bottom of the combustion chamber that is slightly away from the screen plate and close to the flame opening, and cooling air jets that blow out cooling air toward this flame holding plate are installed. A forced combustor characterized in that an outlet is provided in the secondary air jet plate and the screen plate.
