At this time, the sludge is actively burned through the air supplied from the air chamber 38 formed under the combustion chamber 36 in the combustion process. That is, when the sludge is burned as described above, the cold water in the storage space 12 is first heated by hot water having an appropriate temperature due to the heat generated therein.

On the other hand, when the sludge burns in the combustion chamber 36, a high heat gas is generated, and the hot water is heated again by using the heat of the high heat gas by circulating the high heat gas to the heat exchanger 50.

That is, when high heat gas is generated in the combustion chamber 36, the high heat gas is introduced into the first circulation duct 52 through the first cyclone 48. At this time, the first cyclone 48 filters the dust generated together with the high heat gas by centrifugal force and introduces only the high heat gas into the first circulation duct 52, thereby preventing the dust that is a pollutant from being discharged to the outside. In addition, the filtered dust is completely burned in the combustion chamber so that the combustion efficiency can be increased as well.

Thereafter, the high temperature gas introduced into the first circulation duct 52 flows into the second circulation duct 54 through the square hole 56 formed in the second circulation duct 54. At this time, the high temperature gas introduced into the second circulation duct 54 is heated to a higher temperature by using the thermal power generated in the auxiliary burner 59 installed in the second circulation duct 54, and thus the heat exchange of hot water. It is possible to increase the efficiency.

Subsequently, the high heat gas passes through the second cyclone 60 penetrated at one end of the second circulation duct 54. In this process, the dust in the high heat gas is once again filtered out, and only the high heat gas that is gas is used. Pass through the two cyclones (60).

Next, the high temperature gas passing through the second cyclone 60 flows into the first passage part 64 positioned at the upper end of the housing 10, and then passes through the plurality of first heat exchange pipes 70 to connect the passage. After moving to the part 78, the second heat exchange pipes 72 pass through the third passage part 66, and then are discharged to the outside through the exhaust port 80.

That is, as described above, the hot water is primarily heated by using the heat generated by the combustion device 32, and the first and second circulation ducts 52 and 54, which are the heat exchanger 50, are used to heat the high-temperature gas generated during the combustion process. By circulating the first and second heat exchange pipes 70 and 72 to heat the hot water again by using the heat of the high heat gas, the heating efficiency of the hot water can be increased.

As discussed above, the present invention achieves many effects as follows.

Firstly, sludge produced by crushing industrial waste materials can be used as a boiler raw material, which has the effect of reducing fuel costs.

Second, there is an effect to prevent the pollution of the environment by preventing the dust, which is a pollutant generated during the combustion of the sludge to the outside.

Thirdly, by allowing the hot water to be heated again by using the hot gas generated from the combustion of the sludge, it is possible to increase the heating efficiency of the hot water, thereby increasing the combustion efficiency and the heating efficiency.
