Problems solved by technology

[0003] However, for this kind of burner, when the input to the burner is increased, the combustion state of the mixed gas ejected from the flame port of the burning area will be deteriorated due to insufficient secondary air, so that the concentration of carbon monoxide in the combustion exhaust gas will increase

Embodiment Construction

[0020] refer to figure 1 , figure 2 , 1 denotes a combustion case constituting a combustion device including a heat source machine for hot water supply. The upper surface of the combustion case 1 is open, and a heat exchanger for supplying hot water (not shown) as an object to be heated is provided above the combustion case 1 . In the combustion housing 1, a combustion chamber 2 and an air supply chamber 3 on the lower side of the combustion chamber 2 are arranged. The air supply chamber 3 is separated from the combustion chamber 2 by a partition plate 4 . In the combustion chamber 2, a plurality of burners 5 long in the front-rear direction are arranged side by side with a gap in the lateral direction.

[0021] A combustion fan (not shown) is connected to the bottom surface of the air supply chamber 3 , and air is supplied to the air supply chamber 3 from the combustion fan. A plurality of distribution holes 41 are formed in the partition plate 4 . And the air supplied ...

Abstract

The present invention provides a combustion device, in which a plurality of burners (5) having a flame port for ejecting a mixed gas at the upper end and having a longer length in the front-rear direction are arranged in parallel in a combustion chamber with a gap in the lateral direction. The end of the burner (5) in the front-rear direction of the flame-portion forming area is defined as a burn-in area (59), and the gap between each burner (5) is located at the same position as the burn-up area (59). A burn-in plate (18) that prevents the secondary air from rising is arranged near the upperend of the front-rear direction portion, and it is possible to suppress deterioration of the burning state of the burn-in area (59) when the input is increased. So the half (18a) on the other side ofthe burner plate (18) in the front-rear direction is inclined toward the other side in the front-rear direction and downward, or formed a step shape so as to extend to the other side in the front-reardirection in a manner of facing a downward step.

Description

technical field [0001] The present invention relates to a combustion device. The combustion device has a combustion shell, and a combustion chamber and an air supply chamber on the lower side of the combustion chamber are arranged in the combustion shell. A plurality of long burners are arranged side by side in the combustion chamber with gaps in the lateral direction, and secondary air is supplied from the air supply chamber to the combustion chamber in an ascending manner. Background technique [0002] At present, with regard to such a combustion device, the following combustion device is known: the end portion on the front and rear direction side of the flame port forming area at the upper end of each burner is set as a burning area, and the gap between each burner is located at the same position as the burner. In the vicinity of the upper end of the portion in the front-rear direction where the flame spread area is the same, a fire spread plate that prevents secondary ai...
