The present invention is a boiler in which a water collecting chamber and a hot water heating tank are formed in the upper and lower parts of the boiler, and a plurality of hot water heating rise tubes are integrally formed so that the inner and outer surfaces of the hot water heating tank are uneven to receive the heat of the combustion chamber. The area is increased to effectively use the heat of combustion in the combustion chamber, and the combustion air is smoothly supplied to the combustion chamber by a plurality of recesses formed on the inner wall surface of the hot water heating tank by the plurality of hot water heating pipes. By limiting the inner diameter of the ascension pipe to a specific state to prevent convection of hot water in the boiler body to provide a boiled hot water boiler to promote the natural circulation of hot water in the heating pipe.

Conventionally, in the boiler, the hot water heating tank at the bottom of the collecting chamber is formed as a general body, and the hot water heating tank receiving the combustion chamber has a narrow heat receiving area, and thus, there is a drawback of not using the heat of combustion in the combustion chamber effectively and causing the waste to deteriorate. The convection of hot water in the boiler fuselage is caused by the difference in temperature between the inner wall that receives direct heating of the combustion chamber and the outer wall that receives indirect heat by waste heat. It occurred that natural hot water circulation in the heating tube was not smooth.

The present invention is to prevent the hot water convection in the hot water heating tank by eliminating the defects of the conventional coal-fired boiler to promote the natural circulation action of the hot water in the heating pipe, the main wall of the hot water heating tank receiving the heating of the combustion chamber It is formed to have an uneven shape to widen the heat-receiving area to effectively use the burnt heat of the coal, and will be described in detail as follows.

In the conventional one in which the hot water heating tank 3 is integrally formed so as to communicate with the collecting chamber 2 on the bottom of the collecting chamber 2 formed above the boiler body 1 made of cast iron, the hot water heating tank 3 ), The lower side is formed into a normal body so as to be the water supply chamber 4, and the main wall of the hot water heating tank 3 to the bottom side of the water supply chamber 4 and the collecting chamber 2 is uneven to form the same shape. The inner recess 5 and the outer recess 6 and a plurality of inner warm water heat riser 7 and outer warm water heat riser 8 are configured to have a zigzag shape. In the figure, reference numeral 9 denotes an exhaust hole through which heat of the combustion chamber is exhausted.

As described in FIG. 3, the present invention has a plurality of inner and outer surface recesses 5 and 6 and inner and outer warm water heating pipes 7 and 8, so that the main wall of the hot water heating tank 3 is uneven. It is formed so that the heat receiving area of the combustion chamber is wider than the conventional hot water heating tank is formed by the conventional body, so that it uses the heat of coal combustion effectively, and the combustion soil pipe inserted into the fuselage 1 by the inner recess 5 is formed. The space is formed between the outer circumferential surface and the inner circumferential surface of the outer warm water pipe 8 to facilitate the supply of combustion air, and the water supplied in the inner and outer warm water pipes 7 and 8 is heated to provide high temperature hot water. Since it is raised to the collecting chamber (2), the hot water convection action does not occur inside the hot water heating tank (3), so that the absorption port of the inner and outer hot water heating pipes (7) (8) communicating with the water supply chamber (4) Strong suction force due to negative pressure The hot water in the heating pipe shows a function and effect that the natural circulation rapidly.
