ある。（特開昭６０−７８２４７号公報参照）2. Description of the Related Art Conventionally, in a water heater, a water pipe through which cold water passes is placed near the tip of a flame formed in a gas burner, and the flame temperature is controlled below a certain temperature to suppress the generation of CO in a small combustion space There is a water-cooled combustion device that burns under heavy load. (See JP-A-60-78247)
【０００３】このような水冷方式の燃焼装置は、火炎温

耐久性に問題があった。However, in the conventional water-cooling type combustion apparatus, the cooling water pipes or the cooling fins are directly contacted with the flame of the burner and roasted, so that there is a problem in durability.
【０００５】本発明の目的は、冷却フィン或いは冷却水
管で構成される冷却手段に、火炎が直接接触しないよう

いようにしてある。Reference numeral 1 denotes a combustion tube having a large number of flame holes 2 on the upper surface thereof, and a plurality of air passages 3 are arranged in parallel to form a combustion device. Reference numeral 4 denotes a cooling means provided with a cooling fin and a cooling water pipe provided above the flame hole surface of the combustion pipe 1, and allows cold water to flow inside, and when the flame passes between the cooling means 4, the flame temperature is kept below a certain temperature. Cool to. The flame holes 2 are not provided on the flame hole surface of the combustion pipe 1 below the cooling means 4, and the flame holes 2 are provided avoiding the lower positions of the cooling fins and the cooling water pipes constituting the cooling means 4. This prevents the flame formed in the flame hole 2 from coming into direct contact with the cooling means 4 and roasting.
【００１０】このように構成することにより、冷却手段
