Description

Cokes boiler

The present invention is a porous solid fuel that removes volatility by distilling coal at high temperature, and is low in cost, high calorific value, no harmful gas and harmful substances are not generated during combustion, and the amount of ash after combustion is low. It is related to a coke boiler which is fueled by very good coke (also called bone coal or sea coal).

1 is a cross-sectional view showing a coke boiler according to the prior art.

The coke boiler according to the related art is composed of an inner case 11 and an outer case 12 as shown in FIG. 1 and partitions the inside of the inner case 11 and the boiler body 10 in which water is stored therebetween. To form the fire chamber 11a on the upper side and the dust collecting chamber 11b on the lower side, the coke supply means 30 for supplying the coke 5 to the fire chamber 11a, and the fire chamber. The burner 40 which burns the coke 5 supplied to 11a by the flame which rises from the lower side of the rostol 20, and heats the water, and the coke ash which completed the softening by rotating the rostol 20 (Rostol) Robust stall means for forcibly falling to the dust collecting chamber (11b) through the hole (21) of the 20, and coke ash discharging means (60) for discharging the coke ash dropped into the dust collecting chamber (11b) to the outside Include.

The rostol 20 supports the coke 5 supplied to the inner case 11 so that the coke 5 is accumulated in the firebox 11a, between the rostol 20 and the inner case 11. If the gap is large, the coke 5 is dropped into the dust collecting chamber 11b through the gap so that only a minimum gap for the rotation of the rostol 20 is formed.

The coke supply means 30 is a coke storage hopper 31 to store the coke (5), the coke transfer drum 32 for connecting the lower side of the coke storage hopper 31 and the fire chamber (11a), The coke feed screw 33 is installed inside the coke feed drum 32 to transfer the coke 5 of the coke storage hopper 31 to the firebox 11a, and to apply power to the coke feed screw 33. It consists of a drive motor 34.

The loss stall rotation means 50 is a loss stall rotation shaft 51 installed vertically below the stall 20, the drive motor 52 is installed outside, the power of the drive motor 52 is lost Bevel gear set 53 is connected to the motor shaft 52a of the drive motor 52 and the stall torque shaft 51 so as to be transmitted to the toll rotation shaft 51.

The coke ash discharging means 60 is installed inside the coke ash conveying drum 61 for connecting the lower side of the dust collecting chamber 11b to the outside, and the dust collecting chamber 11b is installed inside the coke ash conveying drum 61. The coke ash feed screw 62 for transferring the coke ash of the outside and the power of the drive motor 52 constituting the rostol rotating means 50 can be transmitted to the coke ash feed screw 62 together. It consists of a spur gear set 63 which connects the shaft 52a and the coke re-feed screw 62.

Reference numeral 71, not described above, is a flue gas pipe that discharges smoke to the outside.

However, the above-described coke boiler of the prior art, first, the coke storage hopper 31 formed to be bulky to store a large amount of coke (5) and the coke transfer drum 32 formed to be relatively small compared to the coke storage hopper (31) Since the circumference of the coke storage hopper 31 is formed to be rapidly narrowed toward the lower side for connection, the coke 5 is entangled at the outlet side of the coke storage hopper 31 so that the coke 5 is fed to the coke transfer drum ( 32) there is a problem that does not discharge smoothly.

Thus, the user had to take the hassle of squeezing the coke 5 by picking it with a rod once every three days.

Second, since the coke 5 has a different size, the larger one among the coke 5 is the coke feed screw 33 of the coke feed screw 33 or the coke feed drum 32 and the coke feed during the feed by the coke feed screw 33. Since the coke 5 is prevented from being smoothly discharged into the firebox 11a because it is interposed between the screws 33 and prevents the coke 5 from being transferred.

Therefore, although the coke boiler may use alternative fuels other than the coke 5, for example, because of the characteristics of the structure, it is not possible to use a replacement fuel of a larger size than the coke 5 by the coke transfer screw 33.

Third, the burner 40 burning the coke 5 accumulated in the firebox 11a located above the stole 20 soars into the firebox 11a through the hole 21 at the lower side of the stole 20. Since the soaring flame necessarily touches the rostol 20 and the rostol rotating shaft 51, the shapes of the rostol 20 and the rostol rotating shaft 51 are curved in an arc shape due to the heat of the flames.

Therefore, when the driving motor 52 is operated, the stall 20 rotates in an inclined state to one side, which causes friction with the inner case 11 during rotation, thereby overloading the driving motor 52. One is true.

Fourth, because the coke ash or pieces of coke (5) is caught in the gap between the stall (20) and the inner case 11 due to its own weight or load to increase the friction between the stall (20) and the inner case (11) There is a problem that the overload of the motor 52 occurs.

Fifth, the foreign matter of the coke (5) contained in the smoke discharged through the exhaust pipe 71 partitions the inner surface of the exhaust pipe (71) by stacking the zig-zag to form a flue by inevitably exhaust pipe (71) ), When the smoke is not discharged smoothly, the smoke flows back into the coke storage hopper 31 through the coke transfer drum 32 communicating with the fire chamber 11a, so that the stored coke 5 is burned due to the heat of the smoke. There is a problem that occurs.

Sixth, the coke (5) usually contains a refractory brick fragment so that only the refractory brick fragment remains when the combustion of the coke (5) is completely made, the refractory brick fragment that does not occur is a hole of the rostol (20) There is a problem that combustion of the coke 5 due to the flame is not smoothly performed because the flame of the burner 40 and the supply of oxygen are interrupted by being caught in the 21.

Seventh, when viewed as a whole by the coke supply means 30 and the coke ash discharging means 60, there is a problem that not only the structure is complicated, but also takes up a large volume of installation space.

The present invention is to solve the problems of the prior art as described above, because the coke is naturally transported as needed by the weight of the coke on the firebox without a separate coke supply means, so it can smoothly supply coke without clogging It is an object of the present invention to provide a coke boiler which is simple in structure and small in volume and which prevents unburned fire bricks from being clogged with a load of coke stacked thereon to prevent clogging of rostol holes.

It is another object of the present invention to provide a coke boiler that prevents the burner flame from directly deforming the coke of the firebox and prevents deformation of the rostol and the rostol rotating shaft due to the heat of the fire.

Another object of the present invention is to change the structure so that the gap between the rostol and the inner case is formed in the horizontal direction rather than in the vertical direction, thereby preventing the coke ash or the coke pieces from being caught in the gap by the weight or the load. To provide.

Another object of the present invention is to form a long length of the flue instead of a diaphragm to prevent the rapid discharge of smoke generated during combustion by the coke boiler to minimize the blockage of the flue by foreign substances contained in the smoke To provide.

As shown in FIGS. 2 and 3, the coke boiler of the present invention divides the boiler body 110 and the boiler body 110 to form a firebox 111a which is a space in which coke C is combusted upward. And a stole 120 forming a dust collecting chamber 113a which is a space where coke ash is collected, a burner 130 for burning the coke C in the fire chamber 111a, and a hole of the rostol 120. Robust stall means for forcibly dropping the coke ash to the dust collecting chamber (113a) through the (121), the boiler main body 110 is connected to the fire chamber 111a and the upper side of the coke storage chamber ( 111b) is formed.

Therefore, since the firebox 111a and the coke storage chamber 111b are connected in series, when the coke C is stored in the coke storage chamber 111b, the coke C is naturally transferred to the firebox 111a by its own weight.

The boiler body 110 is provided with a cylindrical inner case 111 that is elongated up and down, the outer case 112 of the rectangular shape is installed at a predetermined interval around the inner case 111 and the water is stored therebetween; It is formed to communicate with the lower side of the inner case 111 is composed of a support case 113 for supporting the lower side of the outer case (112).

Here, the lower case of the inner case 111 is installed so that the rostol 120 formed in a disc shape having a larger circumference than the lower end of the inner case 111 is horizontally approached.

Therefore, a gap between the lower end of the inner case 111 and the rostol 120 is formed in the horizontal direction.

Therefore, as in the prior art, the phenomenon of coke ash or coke pieces may be minimized due to a gap formed vertically between the inner case and the rostol due to the weight of the coke (C) accumulated thereon or above.

As described above, in the boiler main body 110 in which the stall stall 120 is installed, the fire chamber 111a is a space that is formed in the lower side of the inner case 111 above the stall stall 120. 113a is a space formed inside the support case 113 under the stole 120, and the coke storage chamber 111b is a space formed inside the inner case 111 above the fire chamber 111a. .

The inner case 111 is formed with a coke inlet 111c to be stored again when the coke (C) of the coke storage chamber (111b) is exhausted on the upper side.

The coke inlet 111c is provided with a cover 150 for preventing the heat of the firebox 111a from being unnecessarily escaped to the outside through the coke inlet 111c.

At this time, the cover 150 opens and closes the coke inlet 111c according to the manipulation of the manipulation handle 151 installed above.

Between the inner case 111 and the outer case 112, the first, second, and third partitions 114, 115, and 116 are installed from the inside to the outside in the radial direction, respectively, so that the inner case 111 and the outer case are provided. The space between the sections 112 is divided into four spaces, namely, the first, second, third, and fourth spaces S1, S2, S3, and S4 from the inside to the outside in the radial direction.

Here, the first space S1 and the third space S3 are connected to each other by the first connection pipe 117 to store water for heating and hot water supply.

And the second space (S2) is connected to communicate with each other and the firebox 111a of the inner case 111 by the second connecting pipe 118, one side of the upper side is the outside by the exhaust pipe 119 Connected to each other to form a flue, a passage through which smoke escapes.

At this time, the water is stored in the first and third spaces S1 and S3 preheats the water in the third space S3 to the heat of the second space S2, which is the year, and then opens the first connecting pipe 117. This is to quickly heat the heat of the inner case 111 by flowing into the first space (S1) through.

In addition, since the second space S2, which is a space between the first partition 114 and the second partition 115, is itself a year, the length of the year is lengthened as a whole to prevent rapid discharge of smoke as in the prior art. The diaphragm to make it unnecessary.

On the other hand, the fourth space (S4) is provided with a heat insulating material (H) for preventing the heat of the fire chamber (111a) is transmitted to the outside.

The support case 113 is provided with a coke ash collection box 160 is opened in the upper side to collect the coke ash falling from the fire chamber (111a).

Here, the coke ash collection box 160 is installed to be inserted and pulled out as if the drawer is opened and closed into the dust collecting chamber 113a from one side, and a handle 161 is formed on one side exposed to the outside.

The burner 130 is installed on the side of the boiler body 110 in a vertical direction in the fire chamber 111a so as to directly contact the coke (C) accumulated in the fire chamber (111a) generated during operation.

The rostol rotating means 140 is a rostol rotating shaft 141 is installed so as to be perpendicular to the lower side of the rostol 120, and a drive motor installed in the support case 113 in the vertical direction from the rostol rotating shaft 141 142 and a bevel gear set connecting the motor shaft 142a of the driving motor 142 and the stall shaft 141 so that the power of the driving motor 142 can be transmitted to the stall shaft 141. 143).

Reference numerals 171 and 172 not described above are water supply pipes and drain pipes for hot water supply, and 176 and 177 are water supply pipes and drain pipes for heating.

And reference numeral 180 is a coke amount detection sensor for detecting the amount of coke (C) stored in the coke storage chamber (111b), if the coke amount of the coke storage chamber (111b) is detected by the coke amount detection sensor 180 is less than the set value. The detection signal is transmitted to a controller (not shown) that is electrically connected, and the controller, which receives the detection signal, activates a notification means (not shown) to inject the coke C into the coke storage chamber 111b. It is time to tell.

Looking at the operation of the present invention configured as described above are as follows.

First, the cover 150 is opened by operating the operation handle 151 to open the coke inlet 111c, and then the coke C is introduced into the coke storage compartment 111b to fill the coke storage compartment 111b with the coke C. Then cover 150 is completely closed.

At this time, the coke (C) is naturally dropped into the fire chamber (111a) which is connected to the lower side of the coke storage chamber (111b) by its own weight is accumulated on the rostol (120).

That is, the inner case 111 is filled with coke (C).

Therefore, as in the prior art, coke supply means for artificially supplying coke is unnecessary.

Next, the coke C of the fire chamber 111a is combusted by operating the burner 130.

At this time, the burner 130 is installed on the side of the boiler body 110 to directly contact the coke (C) accumulated in the fire chamber 111a, so that other components are deformed due to the heat of the flame as in the prior art. Is prevented.

Next, when the coke C is burned, the coke C becomes a coke ash and falls into the dust collecting chamber 113a through the hole 121 of the rostol 120.

At this time, the coke C accumulated thereon by the volume of the coke C, which has become coke ash, is naturally transferred from the coke storage chamber 111b to the firebox 111a by its own weight.

That is, whenever the coke C is required to be supplied, the coke C is naturally transferred to the firebox 111a.

Meanwhile, the coke ash dropped into the dust collecting chamber 113a is dropped into the coke ash collecting box 160 and collected.

The smoke generated by the combustion of the next coke (C) is introduced into the second space (S2) that is the year through the second connecting pipe 118 is discharged to the outside by gradually moving to the exhaust pipe 119 along the year, The heat is delivered to the first space S1 located outside the inner case 111 to heat the water.

At this time, since the flue is formed as the second space (S2), as well as preventing the rapid escape of heat to the outside without a diaphragm as in the prior art, the flue of the flue by foreign matter contained in the smoke is also minimized.

Thus, as in the prior art, it is possible to escape the risk of fire due to the backflow of the smoke generated by the flue is blocked.

Next, when the coke (C) is actively burned and the coke ash is accumulated in a predetermined amount or more over the rostol 120, the rotol stall means 140 is operated.

Therefore, when the driving motor 142 is operated, power is transmitted through the bevel gear set 143, so that the rostol 120 rotates at a constant speed.

At this time, the coke ash is forcibly dropped into the dust collecting chamber 113a through the hole 121 of the rostol 120 by the rotational force and vibration of the rostol 120.

The refractory brick pieces contained in the coke and not burned are finely crushed while being rubbed with the rostol 120 by the load of the coke C stacked thereon and the rotational force of the rostol 120. 121).

Therefore, the phenomenon in which the hole 121 of the stole 120 is blocked by the fragments of the refractory brick is prevented.

On the other hand, if you want to process the coke ash filled in the coke ash collection box 160, the coke ash collection box 160 is separated from the support case 113 by pulling the handle 161, and then discard the coke ash.

The present invention as described above has the following advantages because the coke storage chamber is formed so as to be connected to the upper side of the firebox formed in the inner case is naturally supplied to the firebox by its own weight.

First, the coke is entangled at the outlet side of the coke storage hopper, because the coke supply means for artificially supplying the coke as in the prior art, the coke in the coke feed screw or the coke between the coke feed drum and the coke feed screw There is no coke discharge smoothly.

Second, the coke supply means is not necessary, the structure is simple and can be easily installed in a narrow space because the volume is small.

In addition, the present design has the advantage that the burner is installed in the vertical direction in the firebox, the flame of the burner is directly applied to the coke of the firebox, there is no deformation of other components due to the heat of the flame.

In addition, the present invention has the advantage that the coke ash or coke flakes are not easily pinched by this weight due to its own weight or load because the stall is horizontally installed at the bottom of the inner case so that the gap between the inner case and the stall is formed horizontally. .

Therefore, as in the prior art, it is prevented that the coke ash or the coke pieces are caught in the gap, causing the drive motor to be overloaded.

In addition, the present invention is because the second space formed between the inner case and the outer case is the year, the length of the year is long, so as to avoid the need for a diaphragm as in the prior art, it is possible to minimize the blockage of the flue by foreign matter contained in the smoke There is an advantage.

Of course, there is also an advantage to escape the danger of fire that can be caused by flue.

In addition, the present invention prevents the blockage of the stole from clogging the fire brick debris because the fire brick debris on the stole is crushed finely by the load of coke accumulated thereon and the force of the rostol rotating by the rostol rotating means. There is an advantage to this.
