The present invention relates to a furnace tube water-type hot water boiler, and more particularly, to an furnace tube water-type indirect heated hot water boiler.

Typical hot water boilers used in large groups such as bathrooms or hotels are discarded after using hot water heated in heated water tanks in the equipment. Therefore, a large amount of water must be supplied. Indirect heating furnace tube-related hot water boilers are widely used to reduce the above-mentioned obstacles, because they generate obstacles such as deterioration of the heat transfer efficiency of the boiler and shorten the life due to the generated capstone, corrosion, and the like.

An example of the indirect heating furnace-associated hot water boiler is disclosed in 1982 Utility Model Application Publication No. 928, the indirect heating furnace-related hot water boiler forms a pain in the lower portion of the heating water tank, An association is formed between the rear upper part of the furnace and the return chamber by forming a return chamber at the front upper part of the furnace, and a link between the return chamber and the collecting chamber formed outside of the heating water tank is provided. It is formed so that the header is formed on one side over the entire length of the upper part of the heating water tank, and a heat exchanger having a u-type heat exchanger tube installed in the tube plate.

The indirect heating furnace-related hot water boiler burns fuel in the furnace, heats the heat medium such as water filled around the furnace with its radiant flame, heats the heat medium by the combustion gas discharged from the furnace, and then passes through the collecting chamber. While discharging as a stack, cold water is supplied to a heat exchanger and heated by heat exchange with the heated heating medium to be supplied to a bathroom or a user equipment.

However, the above-mentioned indirect heating furnace-associated hot water boiler has a large amount of heat medium and the radiant heat transfer surface is only the furnace and the heating water tank behind it, so the heat transfer area is small. It takes a long time and has low thermal efficiency, and the indirect heating furnace-associated hot water boiler is usually installed in a basement of a building, and since the hot water boiler has a large volume, it is impossible or difficult to transport the finished product to a basement with a small door. Therefore, there is a problem that the leak test is complicated and costly due to the on-site assembly construction by carrying the site in the state of parts.

In view of the above problems, an object of the present invention is to provide a furnace water pipe type hot water boiler which can generate hot water quickly and at the same time improve the thermal efficiency, reduce the volume and transport the site in a finished product state.

In order to achieve the above object, the present invention forms a plate-shaped first heating water tank around the boiler body having a furnace barrel formed in the front lower portion, and at the same time, the heat exchanger communicating with the plate-shaped first heating tank at the top of the furnace barrel. A gas chamber is formed to embed a heat exchanger, and an exhaust passage is formed at an upper portion at a right angle with the furnace at the rear of the furnace and the heat exchanger chamber, and a plate-shaped radiant heating tank communicating with the first heating bath is vertically installed, and the flame is placed in front and rear of the furnace. A chamber and a flue gas chamber are formed, and the flame chamber and the flue gas chamber are provided with a plurality of water pipes parallel to the radiant heating bath and connected to the first heating bath.

FIG. 4 is a cross-sectional view of the second embodiment of the present invention. The difference from the first embodiment is that the second heating water tank 10 installed in the center of the flue gas chamber 9 is omitted in the first embodiment. ') Is installed at the rear lower portion of the boiler body 1, the same components as in the first embodiment are given the same reference numerals and detailed description thereof will be omitted.

According to the present invention as described above, the fuel injected from the burner 26 is burned in the furnace 2 so that the radiant flame heats the periphery of the furnace 2 and simultaneously hits the radiant heating water tank 6 and the flame chamber 8. When switching the direction above, the water pipe 13 installed in the rear of the heat exchanger chamber 4, the first heating water tank 3, the radiant heating water tank 6 and the flame chamber 8 is heated and then burned with combustion gas. The heat transfer area is drastically enlarged by heating the water pipe 13 installed in the flue gas chamber 9 through the flue gas chamber 9 to the stack 25 and 25 ', thereby improving thermal efficiency. In the first embodiment, since the second heating water tank 10 is provided in the flue gas chamber 9, the heat transfer area is enlarged, and the combustion gas heats the front and rear surfaces of the second heating water tank 10 while changing the direction downward, thereby improving thermal efficiency. Will be further improved).

On the other hand, the heat medium such as the water heated in the circumference of the furnace 2 and the rear of the heat exchanger chamber 4, the first heating water tank 3, the radiant heating water tank 6, the water pipe 13, and the like is subjected to convection by the convection action. The cold water gathered in the heat exchanger chamber 4 formed at the top of the c) and supplied through the inlet 53 of the heat exchanger 5 flows into the inflow chamber 58 and the heat exchange tube 52 and the bypass chamber 60, 60.
