FIG. 2 is a front view enlarged view showing a structure of a third exhaust pipe according to an embodiment of the present invention. FIG. 3 is a cross-sectional view of the present invention FIG. 2 is a plan view of the embodiment of FIG.

1 to 3, the apparatus for discharging exhaust gas of a boiler according to an embodiment of the present invention includes a first exhaust pipe (not shown) connected to a first connection pipe 101 of a first boiler 100 installed on a ship, The first and second exhaust pipes 10 and 20 are connected to one end of the first exhaust pipe 20 and the second exhaust pipe 20 is connected to the second connection pipe 201 of the second boiler 200, And a common third exhaust pipe 30 for exhausting the exhaust gas to the atmosphere.

That is, when the exhaust gas generated during the combustion operation of the first and second boilers 100 and 200 is guided through the first and second exhaust pipes 10 and 20, This is an inverted Y-shaped structure. The first and second exhaust passages U1 and U2 having a symmetrical structure through the central partition 30a are formed to discharge exhaust gas to the atmosphere A third connection pipe 32 extending from one end of the discharge pipe 31 and inserted into the other end of the first exhaust pipe 10 and a second connection pipe 32 extending from the other end of the discharge pipe 31, And a fourth connecting pipe 33 into which the other end of the connecting pipe 20 is insert-joined.

The third and fourth connecting pipes 32 and 33 are symmetrical about the discharge pipe 31 in the left and right or front and back directions. The discharge pipe 31 and the third and fourth connecting pipes 32, A pair of partition walls 41 and a flow channel U3 symmetrically arranged to control the discharge flow rate of the exhaust gas generated during the combustion operation of the first and second boilers 100 and 200, respectively, The discharge adjustment rings 40 and 40 ', which are insulators formed in the inner direction, are coupled. In the case of the discharge adjustment ring 40 formed in the discharge pipe 31, the discharge adjustment rings 40 are formed in a multi-stage structure at regular intervals.

The first and second exhaust pipes 10 and 20 and the third exhaust pipe 30 are formed in a chimney 50 and the first and second exhaust pipes 10 and 20 The exhaust pipe 31 of the third exhaust pipe 30 is fixed at the upper end of the stacking facility 50 by the first and second supporting frames 51 and 52, 3 support frame 53, as shown in Fig.

1 to 3, a plurality of first and second boilers 100 and 200 are disposed in a stacking compartment 50 of a ship, One end of the first exhaust pipe 10 and one end of the second exhaust pipe 20 are connected to the first and second connecting pipes 101 and 201 of the first and second boilers 100 and 200, The other ends of the first and second exhaust pipes 10 and 20 are inserted into the third and fourth connecting pipes 32 and 33 of the third exhaust pipe 30 and welded.

At this time, the first and second exhaust pipes 10 and 20 are fixed so as not to flow through the first and second support frames 51 and 52 at the lower end of the stacking facility 50, 30 is fixed to the third support frame 53 at the upper end of the stacking facility 50.

When the exhaust gas is generated by the combustion operation of the first and second boilers 100 and 200, the exhaust gas flows through the first and second exhaust pipes 10 and 20, And the discharge is guided to the central discharge pipe 31 via the third and fourth connecting pipes 32 and 33.

The discharge control ring 40 ', which is an insulating material formed in the inner direction of the partition wall 41 and the flow path U3, is coupled to the third and fourth connection pipes 32 and 33,

The exhaust control ring 40 'regulates the discharge flow rate when the exhaust gas generated during the combustion operation of the first and second boilers 100 and 200 is discharged, The exhaust gas whose flow rate is controlled constantly flows.

That is, the flow rate of the exhaust gas discharged to the discharge pipe 31 through the discharge control ring 40 'is controlled by controlling the flow rate of the exhaust gas generated in the first and second boilers 100 and 200, 10) 20 and the third and fourth connecting pipes 32, 33 connected thereto to be guided to the discharge pipe 31 as it is and to smoothly discharge the exhaust gas from the discharge pipe 31 It is because it does not.

At this time, the discharge pipe (31) is formed with the first and second discharge channels (U1) and (U2) having a symmetrical structure with the central partition wall (30a) The exhaust gas whose flow rate has been firstly adjusted through the third connection pipe 32 flows into the first discharge flow path U1 , The exhaust gas whose emission amount has been firstly adjusted through the fourth connection pipe (33) flows into the second exhaust passage (U2) and then discharged into the atmosphere outside the churn facility (50).

That is, in the embodiment of the present invention, when the exhaust gas is exhausted from a plurality of boilers 100 and 200, the exhaust gas is exhausted through one common exhaust pipe 30, while the exhaust pipe 10 20) 30 so that the exhaust gas can be quickly discharged to the atmosphere while preventing the exhaust gas from being accumulated or being burnt into one side.

The first and second exhaust pipes U1 and U2 as well as the third and fourth connecting pipes 32 and 33 are connected to the vertical center line of the discharge pipe 31, 10) 20 are designed to be symmetrical in the left and right (or front and rear) directions. This is because when the exhaust gas discharged from the plurality of exhaust pipes 10 and 20 is discharged to the atmosphere through one exhaust pipe 30, The amount of the exhaust gas discharged from the exhaust pipe increases.
