In addition, in describing the present invention, when it is determined that the detailed description of the related well-known configuration or function may obscure the gist of the present invention, the detailed description thereof will be omitted.

1 is a view showing the inside of a combustor according to an embodiment of the present invention, Figure 2 is a view showing the inside of a combustor according to another embodiment of the present invention.

Referring to the drawings, the combustor of the present invention is a combustion chamber 100 in which solid fuel F is combusted, a fuel supply unit 200 supplying fuel F to the combustion chamber 100, and the combustion chamber 100. Clinker collecting unit 520 and the clinker collecting unit (C), which includes an air supply unit for supplying combustion air (A) and collects clinker generated by the combustion of fuel (F) in the combustion space (100a) as a main constituent feature. The reflow channel 530 passing through the grate 130 from the 520 to the combustion space (100a). For reference, the clinker includes ash as the material remaining after the fuel is burned.

Here, the combustion chamber 100 has a combustion space (100a) is formed therein, the grate 130 is installed in the lower portion of the combustion space (100a), the discharge port (100c) is formed at the top. At this time, the grate 130 is a configuration in which the fuel (F) is seated on the upper portion is connected to the fuel supply unit 200 in the central portion.

For reference, it is preferable that the combustion chamber 100 has a truncated cone shape as an upper and lower light beam type, which is stable in terms of durability including the downward swing flow of the combustion air A supplied into the combustion chamber 100 to be described later. It can be adopted as a structure. In addition, this structure is an efficient structure by removing the unnecessary inner corner space in the square cross section in terms of gas flow path.

In addition, the grate 130 is rotationally driven around the fuel supply unit 200. As an example, the grate 130 may be directly connected to the driving member to be rotated, and as another example, the turntable (140 of FIG. 2). Is installed on the upper surface of the drive member to rotate the drive turntable 140 can be rotated in conjunction with this. At this time, the direct connection structure of the drive member to the grate and the connection structure through the turntable 140 can be used any structure of course.

In addition, the fuel supply unit 200 may be connected downward to the center of the grate 130 to take a structure for supplying the fuel (F) to the top of the grate (130). As an example, the fuel supply unit 200 may protrude to the combustion space 100a through the grate 130 and may be configured in a screw manner to continuously supply the fuel F by the screw 210.

In addition, the fuel supply unit 200 may be installed at the end of the combustion space (100a) side of the combustion space (100a) may be mounted downward blocking member 220 to be distributed to the side while blocking the upward movement of the fuel (F).

On the other hand, the air supply unit is connected to the side of the combustion chamber 100 to supply the combustion air (A) into the combustion chamber 100, specifically, may be composed of the upper air supply unit 310 and the lower air supply unit 320. have. The upper air supply unit 310 and the lower air supply unit 320 is determined by a position difference relative to each other, and thus is not limited to a specific connection position connected to the side of the combustion chamber 100.

In this case, the upper air supply unit 310 and the lower air supply unit 320 may be configured to take a structure to supply the combustion air (A) to turn along the inner wall 110 of the combustion chamber 100, as an example As shown in FIG. 3, the upper air supply unit 310 may form a connection structure connected to the side of the combustion chamber 100 to be inclined in a horizontal plane. Combustion air A supplied through the upper air supply unit 310 descends while turning along the inner wall 110 of the combustion chamber 100 in the combustion space 100a to the fuel F on the grate 130. As it is preheated before reaching, the combustion efficiency can be increased, and the inner wall 110 of the combustion chamber 100 is blocked by blocking the inner wall 110 from the high temperature distribution site extended upward from the central portion of the combustion chamber 100 toward the outlet 100c. You can drop the temperature.

In addition, the lower air supply unit 320 is connected to the lower side of the combustion chamber 100, the combustion air to rise along the center of the combustion chamber (100) after burning in contact with the fuel (F) above the grate 130 A) serves to supply.

In addition, the upper air supply unit 310 of the air supply unit so that the combustion air (A) is rotated along the outer surface of the inner wall 110 of the combustion chamber 100 and then introduced into the combustion space (100a) through the inlet (100b), The inner wall 110 may be connected to the outer wall 120 of the combustion chamber 100 that surrounds the inner wall 110.

Accordingly, the combustion air A supplied through the upper air supply unit 310 may cool the inner wall 110 while turning upward along the outer surface of the inner wall 110 of the combustion chamber 100, and then the inlet 100b. Through the flow into the combustion space (100a) can be preheated while turning down.

In addition, as an example, as shown in FIG. 2, the combustion air A supplied through the lower air supply unit 320 is introduced into the lower side of the combustion space 100a before the lower inner wall 110 of the combustion chamber 100. The lower inner wall 110 may be cooled while turning downward along the outer surface.

And, in order to achieve the cooling of the inner wall 110 of the combustion chamber 100 with the preheating of the combustion air (A), the combustion air (A) supplied by the air supply unit is guided downward in the combustion chamber (100). It may further include a guide member 400 to.

Here, a swirl flow structure of the combustion air A supplied into the combustion space 100a through the upper air supply 310 of the air supply unit will be described in detail as shown in the drawing.

Specifically, referring to the upper air supply unit 310 as an example, the upper air supply unit 310 is inclined in a horizontal plane on the side of the combustion chamber 100, the combustion air (A) through the inlet (100b) combustion space (100a) When it enters inside, it has a turning force. Specifically, the combustion air A passes through the inner wall 110 and the outer wall 120 of the combustion chamber 100 and then flows into the combustion space 100a through the inlet 100b. Of course, it maintains its turning force even when flowing into 100a).

In this way, the combustion air A, which maintains its turning force even in the combustion space 100a, is pushed by subsequent continuous air which is subsequently introduced. Among these, the combustion air A is rotated while descending, but the fuel F ) And the remaining combustion air (A) is drawn by the high temperature combustion gas flowing upward to the discharge port (100c) side is moved to the center side or the upper side of the combustion chamber (100).

Accordingly, in the present invention, the combustion air A, which maintains the turning force, does not move to the center side or the upper side of the combustion chamber 100, but moves downward through the inner wall 110 of the combustion chamber 100 in the combustion space 100a. The guide member 400 guides the combustion air (A).

In this case, the guide member 400 has a structure which is opened downward while protruding into the combustion space (100a) in the inlet (100b) in which the combustion air (A) is introduced into the combustion space (100a), specifically, the combustion chamber An upper guide plate 410 extending from the structure above the inlet 100b to the inside of the combustion chamber 100a at 100 and extending downwardly from the upper guide plate 410 and spaced apart from the inner wall 110 of the combustion chamber 100. Side guide plate 411 may be provided. At this time, the side guide plate 411 forms an arrangement structure spaced apart from the inner wall 110 of the combustion chamber 100, the upper guide plate 410 is preferably the inlet (combustion space 100a) in the combustion chamber (100) 100b) has a structure extending from the upper end of the position to the side guide plate 411. Of course, if there is a structure of the flange structure on the upper side of the inner wall 110 of the combustion chamber 100, and there is an inlet (100b) of the combustion space 100a between the structure and the inner wall 110, the flange structure The structure of will function as the upper guide plate 412.

In addition, the present invention provides more combustion than the lower air supply unit 320 to the upper air supply unit 310 that supplies the combustion air A above the combustion chamber 100 so that the combustion air A is turned downward as described above. It may further comprise a branch configured to provide an air quantity. By increasing the amount of combustion air provided to the upper air supply unit 310 by such a branch, it is possible to increase the preheating of the combustion air A and the cooling effect of the inner wall 110 of the combustion chamber 100.

In detail, the branch part has a branch wall 341 for branched flow of combustion air (A) inside the air supply line 330 connected to the upper air supply part 310 and the lower air supply part 320 as one flow path. At the end of the branch wall 341, a rotation bar 342 may be mounted to adjust the amount of combustion air flowing into each of the upper air supply part 310 and the lower air supply part 320. Although the pivoting bar 342 is not shown in the drawing, it takes a structure linked to a driving unit that provides a driving force to the pivoting bar 342 to pivot the pivoting bar 342.

On the other hand, according to the present invention, the clinker collecting unit 520 in which the clinker generated by the combustion of the fuel F in the combustion space 100a is collected through the gap 510 and the clinker in the combustion space 100a are provided. In order to increase the removal efficiency, a reflow channel 530 is provided such that the combustion air A flowing out from the combustion space 100a to the clinker collector 520 through the gap 510 is re-introduced into the combustion space 100a. do.

Specifically, the clinker collector 520 communicates downwardly with the gap 510 formed between the inner wall 110 of the combustion chamber 100 and the grate 130, so as to burn the fuel F in the combustion space 100a. It collects the generated clinker through the gap 510.

In other words, the clinker, which is the remaining material of the fuel F, is moved by the combustion air A which swings downward in the combustion space 100a, thereby being located at the lower edge of the combustion space 100a, that is, the combustion chamber 100. Outflow from the combustion space (100a) through the gap 510 formed between the inner wall 110 and the grate 130 of the) is collected in the clinker collector 520.

In addition, the reflow channel 530 has a structure passing through the grate 130 from the clinker collector 520 to the combustion space 100a, and thus the clinker collector through the gap 510 from the combustion space 100a. Combustion air (A) leaked to 520 serves to re-introduced into the combustion space (100a).

Here, looking specifically at the flow structure of the combustion air (A) with respect to the combustion space (100a) and the clinker collecting portion 520, only the gap 510 is the combustion air (A) entering and exiting the clinker collecting portion (520) In the case of the passage, the combustion air (A) is flowed back into the combustion space (100a) through the gap 510 when the combustion air (A) flows out from the combustion space (100a) to the clinker collecting portion 520 through the gap (510) ( By colliding with A), the outflow flow to the clinker collector 520 is not smoothly performed, so that the clinker is not collected efficiently in the clinker collector 520.

Accordingly, in the present invention, the combustion air (A) is a combustion space so that the combustion air (A) flows smoothly from the combustion space (100a) to the clinker collecting portion 520 in order to increase the clinker removal efficiency of the combustion space (100a) A reflow channel 530 is configured to reflow into 100a.

At this time, the reflow channel 530 takes a structure that passes through the grate 130 from the clinker collector 520 to the combustion space (100a), in the lower portion of the combustion chamber 100 as a separate passage from the gap 510. It is only to be formed to pass through the grate 130, the specific structure thereof is of course not limited by the present invention.

As shown in the figure, at least one or more reflow channels 530 may be formed around the central portion of the combustion chamber 100.

On the other hand, the combustion air (A) is re-introduced into the combustion space (100a) through the re-inlet channel 530, but during this re-introduction process, some of the clinker is also returned to the combustion space (100a) with the combustion air (A). Inflow. In detail, the distance from the combustion air flow structure within the clinker collecting part 520 to the combustion space 100a through the reflow channel 530 is greater from the lower portion of the combustion chamber 100 toward the central side. The flow rate is faster, the faster the flow rate, the more easily the clinker is moved back into the combustion space (100a) by the combustion air (A).

Accordingly, as shown in FIG. 4, the reflow channel 530 is reflowed into the combustion space 100a by taking a structure in which the size of the cross-sectional area decreases from the lower portion of the combustion chamber 100 toward the center. In the portion having a high flow rate, the size of the cross-sectional area is relatively reduced, and in the portion where the flow rate is re-flowed into the combustion space 100a is relatively large, the size of the cross-sectional area is relatively large. This can reduce the amount of clinker reflowed. For reference, the cross-sectional area of the reflow channel 530 refers to the cross-sectional area of the angle at which the flow rate is adjusted when the size changes, and refers to the cross-sectional area in the drawing as an example.

In addition, if the reflow channel 530 is formed as shown in Figure 3, although not shown in the figure may be formed narrower toward the center from the lower portion of the combustion chamber (100).

As another example, as shown in FIG. 5, the reflow channel 530 has a structure in which the number decreases from the lower portion of the combustion chamber 100 toward the center side, whereby the flow velocity of the reflow channel 530 is fast. The number of clinkers to be re-introduced back into the combustion space (100a) through the reflow channel 530 as the number is relatively reduced, and the number of the flow rate is re-introduced into the combustion space (100a) is a relatively large number. Can be reduced.

For reference, the reflow channel 530 of FIGS. 3 to 5 described above may have a proper size as the size of the fuel F on the grate 130 does not fall through.

And, as shown in Figure 6 (b), the flow control member is configured to limit the clinker in the clinker collector 520 is re-introduced into the combustion space (100a) with the combustion air (A) 540 may further include.

The flow control member 540 is configured to control the combustion air flow structure in the clinker collector 520, so that the clinker in the clinker collector 520 together with combustion air A into the combustion space 100a. Re-introduction can be limited.

Specifically, the flow control member 540 may have a structure formed to extend downward from the lower portion of the combustion chamber 100 into the clinker collecting portion 520, as shown in Figure 6 (b), and also the combustion chamber 100 It may take a structure extending inclined downward to the center side of the).

Here, when the flow structure of the combustion air in the clinker collector 520 will be described with reference to FIG. 6, first, FIG. 6 (a) shows the combustion air when the flow control member 540 is not installed. 6 (b) is a view showing a combustion air flow structure when the flow control member 540 is installed.

At this time, the combustion air (A) flowed out from the combustion space (100a) to the clinker collector 520 through the gap 510 is converted to the inner surface of the clinker collector 520 in FIG. Immediately re-introduced into the combustion space (100a) through the re-introduction channel 530, but in Figure 6 (b) is a process of moving to the re-introduction channel 530 after the direction change while hitting the inner surface of the clinker collector 520 Is guided by the flow control member 540 in the horizontal direction to the central side of the combustion chamber 100, and then re-introduced into the combustion space (100a) through the re-inlet channel 530.

As shown in FIG. 6 (b), the combustion air A rises at a high speed in the clinker collector 520 at a high speed and is not flowed to the reflow channel 530 by the flow control member 540. By switching in the horizontal direction, the flow velocity is slowed and the flow length is also increased, and as the vortex intensity is reduced instead of increasing the flow diameter rotating below the gap 510 in the vertical direction, the combustion air A is along the combustion air A. It is possible to more effectively implement the separated clinker from the combustion air (A) by the own weight, thereby increasing the clinker collection efficiency of the clinker collector 520.

On the other hand, the present invention, when the combustion air (A) provided by the lower air supply unit 320 is supplied into the combustion chamber 100 through the gap 510, the air supply passage (510a) and the clinker collecting passage (510b) It may further include a partition wall 600 formed in the gap 510 to separate.

The lower air supply unit 320 is connected to the lower side of the combustion chamber 100, so that the combustion air A burns in contact with the fuel F of the upper part of the grate 130 and then rises along the center of the combustion chamber 100. Combustion air (A) is supplied so that the gap 510 may be utilized as a passage flowing into the combustion space (100a) as shown in FIG.

In this case, in the gap 510, the combustion air A flowing out from the combustion space 100a to the clinker collecting unit 520 and the combustion air A supplied from the lower air supply unit 320 to the combustion space 100a. As the flows interfere with each other, the clinker collection efficiency of the clinker collection unit 520 is lowered. In order to prevent this, the partition wall 600 may be installed in the gap 510.

In detail, the partition 600 separates the air supply passage 510a and the clinker collecting passage 510b from the gap 510 so that the clinker may be collected by the clinker collecting portion 520 through the gap 510. It takes a structure, as an example can be arranged in a longitudinal arrangement arranged as shown in the figure, not limited to this, if the air supply passage 510a and the clinker collecting passage 510b is separated from the gap 510 Of course, any arrangement may be taken to correspond to adjacent structures.

In addition, the present invention may further include a check member 700 provided inside the clinker collector 520 as shown in FIG.

The check member 700 serves to block the downwardly passed clinker from upward pass. Specifically, the check member 700 may have a structure in which a plurality of upper and lower pass holes 700a are preferably formed.

As the clinker is easily introduced through the relatively large upper opening in the passage hole 700a of the check member 700, the downward passage of the passage hole 700a is smoothly made, but in the reverse direction. In the case where the passage hole 700a passes upward, the clinker cannot easily pass through the relatively small lower opening so that the passage of the passage hole 700a does not almost pass upward.

The clinker collection efficiency of the clinker collection unit 520 can be increased by the check member 700 configured as described above.

In addition, although not shown in the drawings, water may be accommodated so that the clinker is deposited on the lower portion of the clinker collection part 520. When the clinker is seated on the water, the clinker is not easily separated by the attraction force of the water. If the clinker is deposited in the water, the flow of the combustion air A is not affected at all, thereby further increasing the clinker collection efficiency of the clinker collection unit 520.

As a result, the present invention as described above, the clinker collecting unit (C) so that the combustion air (A) flowing out from the combustion space (100a) to the clinker collecting unit 520 through the gap 510 is re-introduced into the combustion space (100a). The reflow channel 530 configured to pass through the grate 130 from the 520 to the combustion space 100a is configured to smoothly flow the combustion air A from the combustion space 100a to the clinker collection part 520. In addition, the clinker removal efficiency of the combustion space 100a may be increased.

As described above, although the present invention has been described by way of limited embodiments and drawings, the present invention is not limited thereto and is intended by those skilled in the art to which the present invention pertains. Of course, various modifications and variations are possible within the scope of the claims to be described.
