Description

Coke boiler {a cokes boiler}

The present invention relates to a coke boiler.

More specifically, the combustion coke can be rotated and burned to induce complete combustion, and the ash can be removed very efficiently and automatically discharged to the outside to make handling and management very convenient. By improving the composition of the upper flue gas chamber, when smoke and heat are discharged to the outside, they stay for a long time to maximize the dust collection and recovery and thermal efficiency of the ashes scattered.

As is well known, cokes are pore carbonaceous fuels that dry coal at high temperatures to remove volatiles.

In addition, the coke is completely ash in the form of powder, unlike coal or briquettes during the combustion process, so if the coke is used as a fuel, the coke is frequently shaken or turned over in the combustion chamber, and the ash is not discharged from time to time. Air circulation is not smooth and fire is easy to extinguish.

Therefore, conventional boilers using coke as fuel are configured to rock the stole of cast iron in the combustion chamber so that ashes generated during the combustion process fall under the stole. This was caused by the following problems. will be.

That is, since the coke that is always burning on the stall has been settled, the stoll is easily deformed by high heat and is forcibly shaken. This was followed by a closed stage with excessive losses and heat losses, and vibrations had a significant impact on the life and durability of the boiler itself.

In addition, the conventional coke boiler was very cumbersome because it had to withdraw the ash manually by hand in drawing out the remaining ash after combustion, and the waste management was not performed smoothly.

In addition, the conventional coke boiler is configured to discharge heat and smoke fumes directly to the outside during the coke combustion in the combustion chamber, so the ash and gas emissions to the atmosphere are severely released as well as environmental pollution. There was also a discontinuity such as occurrence.

Accordingly, the present invention has been made in view of the above-mentioned conventional problems, and in particular, provides a boiler using coke as a fuel having a low fuel cost and generating high heat in the combustion process, The installed rostol consists of a rotating rostol and a fixed rostol so that the rotating rostol rotates at a low speed by a motor and a reducer, and a redistribution screw is installed at the lower portion of the rostol to automatically discharge ash, and the combustion chamber The upper part is composed of a flue gas chamber, and the smoke and heat discharge is delayed for a considerable time. Accordingly, ashes scattered in the process of burning coke in the combustion chamber are collected and recovered in the combustion chamber, thereby reducing environmental pollution. In addition, the coke is completely burned to maximize heat efficiency and save fuel due to heat loss prevention. While allowing the increase will be made in the management and handling very easy haryeoneunde that purpose.

The space between the circular frame (52 ') of the ashes can be formed (s) is formed, a plurality of fixed rods (511) to maintain the slope and the interval of 30 ° ~ 60 ° at the edge of the fixed rostol (51) ') Is installed to form a coke guide 511.

In addition, a dust collecting part 9 is formed in the shape of a funnel directly below the rostol 5 so as to initially ignite the screw-out 10 and the coke for redrawing so that ash can be transported and discharged under the dust collecting part 9. At the same time, a burner and a blower 100 capable of forcibly supplying air to the combustion chamber and an air control damper 101 are installed.

In addition, in the ceiling center portion of the combustion chamber 1, the exhaust chamber 2 so that the discharge of heat and smoke generated in the combustion chamber 1 is delayed and the fly ash generated during coke combustion is collected and recovered without being discharged to the outside as much as possible. Protruding the retention protrusion (13) having an embryo study (12) in communication with.

The flue gas chamber 2 located above the combustion chamber 1 is composed of a lower flue gas chamber 21 and an upper flue gas chamber 22, and the bottom of the lower flue gas chamber 21 is formed to be inclined toward the exhaust gas 12. One " The guide plate 211 of the "shape is formed, and the inlet 4 into which the coke is input is connected to the upper side wall of the guide plate 211 so that the supplied coke flows naturally on the inclined guide plate 211. It is possible to maximize safety during handling by lowering the inlet (12) and supplying smoothly to the combustion chamber (1) while preventing the heat and flame from entering the inlet when the inlet is opened. The upper exhaust chamber (22) and the lower part Between the flue gas chamber 21, it has a staying protrusion 212 and a flue gas researcher 213 in the center. And a secondary retaining plate 222 having a retaining protrusion 221 at the periphery of the upper side of the exhaust gas researcher 213. The common exhaust pipe 223 installed at the center of the ceiling 22 protrudes into the upper exhaust chamber 22 so that the staying protrusion 224 is formed on the ceiling of the upper exhaust chamber 22. By installing a damper 223 ′ that can control the discharge amount inside the exhaust pipe 223, smoke and heat are transferred from the lower exhaust chamber 21 to the upper exhaust chamber 22, and the exhaust pipe 223 to the outside. By allowing the residence time to be long to be discharged, the heat loss can be minimized, and the efficiency of dust collection and recovery of scattered ash can be increased, and the thermal efficiency can be maximized.

On the other hand, the flue gas chamber 2 is formed long in the vertical direction, and the above-mentioned " "It can also be used to install two or more type retention plate 221, in this case, the heat and smoke, gas, etc. will be retained for a longer time, the effect of increasing the thermal efficiency even more.

According to the present invention configured as described above, when the coke 8 is introduced through the inlet 4, the coke 8 is placed down the inclined guide plate 211 formed at the bottom of the lower exhaust chamber 21. 12 is supplied to the rostol (5) installed in the combustion chamber (1), the inlet (4) is located in the flue chamber (2) rather than the combustion chamber (1) side in the process of injecting coke ( There is no fear that the flame inside 1 will be discharged to the inlet 4.

In addition, the roast stall 5 installed below the combustion chamber 1 is composed of a fixed stall 51 and a rotating stall 52, and only the rotating stall 52 is connected to the motor 6 and the reducer 7. It is configured to rotate at a low speed by the coke guide portion 511 is installed at the edge of the fixed rostol 51 inclined at 30 ° ~ 70 °, the rotation stall when the rotation stall 52 is rotated As the coke located above (52) rotates in the direction of rotation of the rotatable stall 52 by the stirring protrusions 521 and 521 ', the coke being naturally burned is gradually mixed with the coke. At the same time, the coke located in the coke guide 521 acts to collect onto the rotatable stall 52. In addition, the coke (8) burning during this process is mixed and agitated by the stirring protrusions (521, 521 ') installed in the rotary rostol (52) and the ash generated after combustion is rotated with the fixed rostol (51). As it falls into the gap formed between the circular frames of the rostol 52 and falls into the dust collector 9 very efficiently, the air is smoothly supplied to the inside of the coke which is burning, and the combustion is made very stable. The ash dropped to the funnel-shaped dust collector 9 is automatically discharged to the outside by the screw right for re-drawing 10 is to be made very convenient management.
