An enlarged red hot part is formed, and the inner cylinder is made lower than the middle cylinder, and the upper end of the inner cylinder is erected from the lid, and is located above the middle cylinder and the glass outer cylinder and larger than the diameter of the inner cylinder. A large-scale secondary combustion chamber surrounded by the middle cylinder and the flame expansion plate is formed above the inner cylinder, and further the upper part of the red hot part and the outside of the glass facing the secondary combustion chamber Far-infrared radiation means comprising a cylindrical body is provided outside the cylinder .
[0007]
As a result, the far-infrared radiation means provided at the position facing the secondary combustion chamber that is the highest temperature in the combustion cylinder is strongly exposed from the upper part of the red hot part that is heated by the heat of the secondary combustion in the secondary combustion chamber. It is heated by near infrared rays, radiates far infrared rays from its surface, stimulates the warm point of the human body and improves the feeling of heating, and the combustion heat generated by the complete combustion of the secondary combustion is released indoors. Thus, indoor heating is performed as usual, and a large amount of far infrared rays can be reliably and concentratedly generated, and good heating in which far and near infrared rays are mixed is obtained, which is extremely convenient.
[0008]
Further, if the far-infrared radiation means is constituted by a rust-treated cylinder, it can be used without deterioration in performance over a long period of time.
If the far-infrared radiation means is composed of a cylindrical body having a surface coated with a far-red paint, it can be provided very simply and inexpensively.
