Description
The present invention relates to a clinker-reduced incinerator boiler system.
The incinerator boiler system is a system that uses the heat generated by incineration of waste for heating or power generation.
The incinerator boiler system consists of a combustion chamber and a boiler.
The combustion chamber is composed of a first combustion chamber, a second combustion chamber, and a third combustion chamber.
The first combustion chamber is made of refractory bricks. The second combustion chamber, and the third combustion chamber are made by welding the water pipes through which water flows. The body of the boiler is made by welding water pipes to each other.
The combustion gas generated as the waste is incinerated in the first combustion chamber passes through the second combustion chamber, the third combustion chamber, and the boiler and is discharged to the atmosphere.
While the combustion gas passes through the interior of the second combustion chamber, the third combustion chamber, and the boiler, the heat contained in the combustion gas is transferred to the water flowing through the water pipe. The heat is supplied to the heating or power generation facilities.
The inside of the first combustion chamber is a high temperature of 900 to 1500 ° C. Due to such a high temperature, the waste is hot-welded to the inner wall of the first combustion chamber. The high-temperature welded waste hardens and sticks to the inner wall of the combustion chamber. The waste adhering to the inner wall of the combustion chamber hardly is called a " clinker ".
When the clinker sticks to the inner wall of the first combustion chamber, the incineration capacity is reduced. Therefore, the clinker should be removed periodically (1 to 1.5 months). In order to remove the clinker, the incineration boiler system is shut down and the operator enters the first combustion chamber and breaks the clinker that has clung to the inner wall of the first combustion chamber with a hammer.
In such a short cycle (1 to 1.5 months), the clinker sticking to the inner wall of the first combustion chamber was removed, so that the operation of the incineration boiler system had to be stopped frequently.
In order to solve such a problem, in the patent document (10-1470569), the first combustion chamber is constructed by welding water pipes not refractory bricks to each other so that water flowing in the water pipe cools the inner wall of the first combustion chamber, So that it can not be welded to the inner wall of the housing at a high temperature. As a result, the clinker can be prevented from sticking to the inner wall of the first combustion chamber to some extent.
However, in the registered patent, too, the dust is caught between the narrow gaps between the water pipes welded to each other, and these dusts accumulate and cover the water pipe.
As a result, the cooling efficiency of the water tube is lowered, and the phenomenon that the waste is hot-melt-bonded to the inner wall of the first combustion chamber eventually occurs again. Therefore, it is difficult to increase the period of removing the clinker sticking to the inner wall of the first combustion chamber.
SUMMARY OF THE INVENTION It is an object of the present invention to provide a clinker reduction type incineration boiler system capable of increasing the period of removing the clinker sticking to the inner wall of the first combustion chamber.
To achieve the above object, a clinker reduction type incineration boiler system comprises:
A first combustion chamber composed of water tubes, partition plates disposed between the water tubes and welded to the water tubes;
A second combustion chamber communicating with the first combustion chamber;
A third combustion chamber communicating with the second combustion chamber;
A boiler communicating with the third combustion chamber and comprising a body, an upper drum, a lower drum, and a superheater; And
And clinker reduction devices installed on the diaphragm.
The present invention places a diaphragm between the water pipes of the first combustion chamber, thereby eliminating the gap between the water pipes. As a result, the dust can not be trapped in the gap and the dust can not cover the water pipe. Therefore, the cooling efficiency of the water tube is maintained, and the clinker does not stick well to the inner wall of the first combustion chamber.
In the present invention, the clinker reduction devices installed in the diaphragm of the first combustion chamber discharge air. The discharged air blocks the dust from adhering to the water pipe of the first combustion chamber. Because of this, dust can not accumulate in the water tube, and the dust can not cover the water tube. Therefore, the cooling efficiency of the water tube is maintained, and the clinker does not stick well to the inner wall of the first combustion chamber. In addition, the clinker reduction device supplies a sufficient amount of air to the first combustion chamber to completely combust the waste, so that the amount of waste generated by the clinker itself can be reduced. As a result, the clinker sticking to the inner wall of the first combustion chamber is reduced.
Further, the clinker reduction device is provided with injection ports on the top surface as well as on the side surface. Therefore, not only the forward direction but also the lateral direction dust can be prevented from sticking to the water pipe. Because of this, dust can not accumulate in the water tube, and the dust can not cover the water tube. Therefore, the cooling efficiency of the water tube is maintained, and the clinker does not stick well to the inner wall of the first combustion chamber.
In addition, the clinker reduction device is provided with injection ports inclined downwardly toward the diaphragm on the top surface as well as on the side surface. Therefore, not only the forward direction but also the lateral direction dust can be prevented from adhering to the water pipe, and the discharged air can beat the diaphragm and remove dust attached to the diaphragm. Because of this, dust can not accumulate in the water tube, and the dust can not cover the water tube. Therefore, the cooling efficiency of the water tube is maintained, and the clinker does not stick well to the inner wall of the first combustion chamber.
Therefore, by using the present invention, it is possible to reduce the clinging of the clinker to the inner wall of the first combustion chamber, and to increase the period for removing the clinker sticking to the inner wall of the first combustion chamber from 1 to 1.5 months to 4 to 5 months . As a result, the time for operating the incineration boiler system can be increased.
