Title:
熱交換式ボイラー
Document Type and Number:
Japanese Patent JP2004520563
Kind Code:
A
Abstract:
The present invention relates to a heat exchanging type boiler that includes: a water retaining reservoir 10 in which a predetermined amount of water is charged; and a combustion chamber 33 for emitting heating gas at a high temperature to the water in the water retaining reservoir 10 through a heating gas supply pipe 20 such that the water in the water retaining reservoir 10 is raised to produce steam at a high pressure, the boiler characterized in that a water discharging film 32 disposed between the heating gas supply pipe 20 and the water and having a plurality of fine through holes such that the water in the water retaining reservoir 10 is not leaked to the combustion chamber 33 and at the same time the heating gas emitted to the water by means of the heating gas supply pipe 20 is distributed in substantially small bubble form. Thus, water heating speed can be considerably increased, heat efficiency of the boiler can be more improved, a volume of the boiler can be decreased, the life of the boiler can be semi-permanently extended since the water retaining reservoir is not directly heated, and the cleaning of the interior of the boiler can be carried out in an easy manner.
