As shown in Figure 1 the injection path of the solid fuel is moved in the direction of the arrow A, that is, the movement of the fuel according to the present invention is the fuel storage portion (not shown in the figure) on top of the boiler body (1) The fuel is dropped into the fuel inlet 25 by its own weight, and the upper portion of the inner cylinder 4 is formed to be gradient in a double shape to smoothly supply the fuel.

In the present invention, each fuel charging control unit (8, 9, 13, 14) is composed of a sliding plate (6, 6 ') and a fixed plate (7) in contact with each of the sliding plate (6, 6'), A fourth (a) in the insertion hole 30 formed by coupling the upper cylinder 28 with the locking projections 26 and the support projections 27 of the outer cylinders 2 and 3 and the lower cylinder 29 to be fitted thereto; As shown in the figure, the fixing plate 7 is fixed to the outer cylinders 2 and 3 using fastening means such as connecting pins, while the sliding plates 6 and 6 'are fixed to the respective fixing plates 7. Rotate freely to fit.

As shown in FIG. 1, the first fuel charging control unit 8 serves as a diaphragm separating from the combustion chamber of the boiler, and the second fuel charging control unit 9 waits for solid fuel to be introduced into the first combustion chamber. The shield door 11 installed between the second fuel charging control unit 9 and the third fuel charging control unit 13 has a fuel injection path according to whether the fuel is injected around the pivot shaft 10. 5) freely to control the opening and closing, and also prevents the combustion gas generated in the combustion chambers 31 and 34 from passing through the fuel injection passage 5 so that only the combustion gas outlet 32 passes through, and the fuel reduction plate 12 is fueled. It is fixed between the inner cylinder (4) and the lower outer cylinder (3) across the injection passage (5) and formed as a plate formed in a hole or a net shape so that the coal mass, which is a solid fuel, so that the solid fuel that falls into the fuel The free fall speed is decelerated by hitting the reduction plate 12 The.

A first combustion chamber 31 formed between the third fuel charging control unit 13 and the fuel reduction plate 12 and a third fuel charging control unit 13 and a fourth fuel charging control unit 14 formed between the first combustion chamber 31 and the fuel reduction plate 12; In order to increase the combustion effect of the fuel combusted in the combustion chamber 34, wastes communicated with the outside by forming an air inlet 33 on the side wall and the lower side of the inner cylinder 4 forming the combustion chambers 31 and 34. Combustion air flowing through the discharge passage 38 is supplied to the holes 36 of the sliding plates 6 and 6 'of the first and second combustion chambers 31 and 34, and the fuel is introduced through the air inlet 33. Induces complete combustion of.

Briefly describing the fuel injection path according to the present invention is as follows.

The solid fuel is moved from the first fuel charging control unit 8 to the second fuel charging control unit 9 through the fuel injection passage 5, and passes through the shielding door 11 and the fuel reduction plate 12 to the first fuel injection system. After the combustion chamber 31 reaches the third fuel charging control unit 13 in which the combustion chamber 31 is first burned, the waste that is completely burned and re-applied in the fourth fuel charging control unit 14 in which the second combustion chamber 34 is formed is boiled. It settles to the inclined guide path surface 35 installed in the inner bottom, and discharges it to ashes.

Here, the sliding plates 6 and 6 'of each fuel charging control unit 8, 9, 13 and 14 are controlled by a stem motor gear 23 controlled by a known microprocessor not shown in the drawings. The upper gear 20 mounted on each rod 16, 17, 18, 19 is provided in contact with the gear piece 15 formed on the sliding plate 6.6 ', and the motor gear 23 is an internal gear ( 22) The lower gear 24 of each rod 16, 17, 18, and 19 is in contact with the gear piece 21 of the inner gear 22 in order.

The lower gear 24 of each of the rods 16, 17, 18, and 19 engaged with the gear piece 21 of the inner gear 22 is as shown in FIGS. 2 and 3 (a). When the lower gear 24 of one rod is engaged and rotates in the clockwise direction, the lower gears 24 of the other rods which do not come into contact with the gear piece 21 of the inner gear 22 do not rotate. For example, when the lower gear 24 of the first rod 16 is engaged with the gear piece 21, the lower gear 24 of the second rod 17 is engaged, and then the fourth rod 19 is engaged. Since the lower gear 24 of the lower gear 24 and the lower gear 24 of the third rod 18 are sequentially engaged, the upper gear 20 and the lower gear 24 of each of the rods 16, 17, 18, and 19 are The upper gear 20 rotates in the same manner as the lower gear 24 rotates integrally coupled to the rod.

Therefore, when combusting the fuel introduced into the first combustion chamber 31 first, open the see-through door (not shown) attached to the boiler body 1, burn the solid fuel with the ignition coal, and then operate the stem motor. By adjusting the microprocessor, the motor gear 23 rotates and the upper and lower gears 20 and 24 of the rods 16, 17, 18, and 19 rotate according to the rotation of the motor gear 23. FIG. do.

Herein, the operation relationship between the upper gear 20 of each of the rods 16, 17, 18, and 19 and the gear piece 15 of the sliding plates 6 and 6 'will be described in detail.

The fourth rod 19 in which the gear piece 21 of the inner gear 22 is engaged with the gear piece 15 formed on the sliding plate 6 of the fourth fuel charging control portion 14 by the control of a known microprocessor. After rotating the upper gear 20, the upper gear 20 of the third rod 18 rotates the gear piece 15 formed on the sliding plate (6 ') of the third fuel charging control unit (13) Since the upper gear 20 of the first rod 16 rotates the gear piece 15 formed on the sliding plate 6 of the first fuel charging control unit 8, the solid fuel is a hole of the sliding plate 6. 36 'and the hole 36' of the fixed plate 7 coincide with each other and fall to the second fuel charging control unit 9.

In this case, when the sliding plate 6 of the first fuel charging control unit 8 is rotated about half, the sliding plate 6 of the second fuel charging control unit 9 can be opened for the first time, as shown in FIG. Likewise, the lower gear 24 connected to the second rod 17 for rotating the second fuel charging control unit 9 to the gear piece 21 of the inner gear 22 is the lower gear of the first rod 16. (24) and spaced apart at appropriate arc spacing. Accordingly, the fixing plate 7 of the second fuel charging control unit 9 and the holes 36 and 36 ′ of the sliding plate 6 are aligned so that the fuel passes through the fuel reduction plate 12 to the first combustion chamber 31. It is dropped to the third fuel charging control unit 13 formed.

In addition, in the first combustion chamber 31 formed in the third fuel charging control unit 13, the fuel is primarily burned, and when the fuel is burned below a predetermined temperature, a temperature sensing sorting sensor (not shown) The control of the microprocessor connected to the motor gear 23 rotates to match the hole 36 'of the sliding plate 6' with the hole 36 'of the fixed plate 7 so that the primary burned fuel is the internal gear. The fourth combustion chamber 34 is formed by the sliding plate 6 'of the third fuel charging control unit 13 which operates in conjunction with the lower gear 24 engaged with the gear piece 21 of the 22. The second combustion occurs by falling into the fuel charging control unit 14, and the completely burned ash is inclined to the guide path surface 35 by the operation of the sliding plate 96 of the fourth fuel charging control unit 14. Along the guide road surface 35 is stacked by ash.

Meanwhile, as shown in FIG. 3 (b), the fixing plate 7 constituting the first and second fuel charging control units 8 and 9 and the hole 36 of the sliding plate 6 are almost the same, As shown in FIG. 3 (c), the fuel charging control unit 13.14 has the holes 36 'of the sliding plate 6' larger than the holes 36 'of the fixed plate 7, so that the wastes are interleaved with each other. The air introduced through the discharge passage 38 is supplied into the first and second combustion chambers 31 and 34.

In addition, the sliding plate (6, 6 ') of the first, second, third, fourth fuel charging control unit (8, 9, 13, 14) is connected to the return spring (37) fitted to the pin formed on the fixing pin (7) Since the sliding plates 6 and 6 'are rotated while tensioning the return spring 37 when the sliding plates 6 and 6' are rotated by the upper gear 20, the upper gear 20 is formed of the sliding plates 6 and 6 '. After rotating in engagement with the gear piece 15, the sliding plates 6, 6 'are returned to their original positions by the restoring force of the return spring 37. At this time, the upper gear 20 is the sliding plate ( 6,6 ') rotates in the opposite direction to the gear piece 15 and returns to its original position, but the lower gear 24, which rotates integrally with the upper gear 20, is idling on the circumference of the inner gear 22.

In this way, opening and closing of the sliding plates 6, 6 'of each fuel charging control unit (8, 9, 13, 14) is controlled by the control unit, the first fuel charging control unit (8), the third fuel charging control unit (9) ), The fourth fuel charging control unit 14 and the second fuel charging control unit 13 are automatically made in a continuous cycle, and the air sucked into the fuel waste discharge passage 38 is shown in FIG. As described above, holes formed in the air inlets 33 formed on the side walls of the first and second combustion chambers 31, 3, and 4 and the sliding plates 6 and 6 ′ of the third and fourth fuel charging control units 13 and 14 ( 36) to help the complete combustion of the fuel and the combustion gas is discharged to the outlet 39 while turning inside the boiler in the direction of the arrow B.

At this time, since the water pipe 40 is directly and indirectly heated by combustion gas and combustion heat, the boiler of the present invention can obtain high thermal efficiency, and complete combustion of solids completely by the action of the first combustion chamber 31 and the second combustion chamber 34. The waste treatment of the fuel is settled to the inclined guideway surface 35, and when it is necessary to take advantage of the re-collecting and charging of fuel, if you do the charging of the fuel, the continuous combustion will proceed automatically. As a result, it is possible to avoid waste of manpower and to use various solid fuels in various ways.
