The present invention relates to a waste heat recovery system of a centralized heating system, and more particularly, to effectively remove waste heat contained in exhaust gas discharged and installed in exhaust flue which guides exhaust gas generated from a boiler and discharged during combustion. The present invention relates to a waste heat recovery system of a centralized heating system that maximizes energy efficiency by heating heating absorbent heating water.

In general, apartments scattered throughout the country are equipped with a centralized heating system to supply heating water to each home.

1 is a schematic schematic diagram of a conventional centralized heating system, as can be seen in the figure, the centralized heating device is installed at least one or more water supplied to the boiler room 60 at a predetermined temperature Boiler 61 for heating in the furnace, exhaust flue 62 installed so as to exhaust the exhaust gas discharged from the boiler 61 to the outside of the boiler room 60, and the heating water heated from the boiler 61 A first heating water circulation line 64 for forcibly returning to the boiler 61 via individual heat exchanger heaters 63 for reheating the cooled heating water during circulation, and the heater means for each heat exchanger ( It is composed of a second heating water circulation line 65 for forcibly circulating the heating water to each home via (63). Thereby, the heating water heated from the boiler 61 is forcibly returned to the boiler 61 as a return pump 66 through the heat exchanger heaters 63 along the first heating water circulation line 64. The second heating water circulation line 65 is continuously circulated by the heat exchange heater means 63 to perform heating of each household, and the reference numeral 67 denotes a heating circulation pump.

However, the conventional centralized heating system as described above has extremely low energy efficiency and high fuel consumption because the high temperature waste heat discharged as exhaust flue is discharged to the outside. There was a problem. Therefore, in recent years, a waste heat recovery device is installed so that the heating water in the line is heated by the exhaust gas discharged at a high temperature in the exhaust flue of the heating system and latent heat, which is a high heat amount generated during combustion, and then the heating water heated by the waste heat recovery device is designated. A number of waste heat recovery systems have been proposed that can be circulated continuously to the home to provide the desired heating.

The heat absorbing fins 74 are spirally formed on the outer circumference of the heat absorbing tube 71. It is proposed to maximize the surface area on the outer periphery of the heat absorption tube 71 to absorb the heat of the exhaust gas.

By the way, the conventional waste heat recovery machine as described above, is formed to be continuously repeatedly bent at a predetermined interval so that the heating water flows inside the body is adopted to install a heat absorbing pipe of the way that the purified line is connected to each end, respectively. As a result, there is a closure that does not allow efficient heat management.

In addition, the conventional heat absorbing tube has a disadvantage in that waste heat cannot be effectively absorbed since the straight pipe is used, and scale and the like accumulate inside the tube to maintain initial performance for a long time.

Accordingly, an object of the present invention is to provide efficient heat management by installing a heat transfer chamber and a heat transfer tube so as to be opened at the heat sharing chamber side, and inside the heat transfer tube by self-cleaning action by the flow of hot water due to the vortex of the hot water by the heat transfer tube. It is to provide a waste heat recovery system of a centralized heating system that does not accumulate scales and maintains initial performance.
