Abstract

An auto coal boiler is provided to maximize the efficiency of a boiler by inducing a complete combustion due to the effective supply of the blowing while executing a continuous combustion via a combustion unit. An auto coal boiler comprises a body(100), a combustion unit(200), a blowing unit, a carbonaceous discharging unit(400), and a carbonaceous receiving unit. The body is composed of a hopper(130) for supplying the coal to have a receiving chamber(120) for having a discharging unit discharged to a flue(140) by passing the heating source at the upper part of a combustion chamber(110) formed on the lower part. The combustion unit executes the combustion function of the coal supplied from the hopper on a furnace block(220) installed continuously at a chain conveyer(210) driven at the predetermined transmission speed at the combustion chamber. The blowing unit is installed at the positions of the furnace block with a blowing dividing unit at a duct connected to a blower placed at outer one side of the body. The carbonaceous discharging unit transmits the carbon ash to the one side of a space unit by a transmission screw mounted on a carbonaceous passage(420) which is flowed by the carbon ash burned at the lower transmission direction of a chain conveyer. The carbonaceous receiving unit discharges the carbon ash collected to one side of the space unit by the carbonaceous discharging unit to be received via each basket positioned at the predetermined intervals of the chain conveyer to a discharging port positioned at the upper part.

In the present invention, the process of feeding, combusting and pulverizing continuously by the orbital combustion method and collecting the burned coal ash while inducing the complete combustion by increasing the thermal power by the efficient arrangement of the tuyeres is performed. It is about automatic coal boiler to be made.

In general, coal boilers are widely used in various forms, but oil boilers are easy to use due to the hassle of using coal boilers. In recent years, however, the oil cost has been soaring, and it is being converted into a coal boiler having a low heating cost.

However, boilers applied in houses, etc., have a large capacity and should be convenient for use. However, conventional coal boilers have a considerable inconvenience in use and do not expect sufficient heating efficiency.

In other words, the roaster for burning coal is fixed and a certain time is required before the coal supplied thereon in a limited area is burned in a stacked state, and it takes a considerable time for a normal boiler to operate. There was a problem of deterioration.

In addition, since the burned sludge falls on the carbon steel storage container provided below by the natural fall, there is a hassle that has to be discarded from time to time, and some carbon materials have a waste of resources in which incomplete combustion carbon materials are considerably discarded.

The flue gas chamber 152 formed on the side of the flue 140 and the opposite side is formed with material spheres 141 and 155 having opening and closing plates, respectively.

The hopper 130 may be provided with a pair of rollers 132 to form guide plates (131, 131 ') for inducing input, and to supply the coal injected directly below the upper guide plate 131 to an appropriate size or less. have.

Each of the chain conveyors 210 and 510, the blower 310, the grinding roller 410, and the transfer screw 430 may be driven by the operation of each motor in accordance with a signal of a separate control device, not shown. It is to be driven by each.

Referring to the operating state of the present invention configured as described above are as follows.

In the first operation of the present invention, first, a sufficient amount of coal is fired by using a plurality of lightning coals or the like at the inlet side of the chain conveyor 210 of the combustion means 200 so that the coal is ignited so that the combustion state is sufficiently achieved. 130, when the appropriate amount of coal is put into the organic operating state of each device by the drive and power transmission member of each motor by the application of power, the oven block by the chain conveyor 210 provided in the combustion chamber 110 Coal which is located at the inlet of the 220 is combusted and the coal operation is carried out while the coal is introduced into the inlet of the chain conveyor 210 by the guide of the guide plate (131,131 ') from the hopper 130 is burned And piled up and accumulated in the vicinity of the coal is ignited and the combustion is made at the same time as the operation of the chain conveyor 210, the oven block 220 is extremely fine As the coal accumulated at the inlet is burned and transported, the coal is repeatedly inserted at the rear as it is transported. This is to adjust the speed according to the quality of coal, combustion conditions.
At the same time, since the air generated from the blower 310 is blown in the direction of an appropriate angle at each set position of the oven block 220 through the plurality of blower distribution ports 330 via the duct 320, combustion is smoothly made. As it is continuously burned by the coal injected into the coal, the coal is almost burned when it reaches the rear of the conveying direction of the oven block 220 on the chain conveyor 210.

In addition, six blowing distribution ports 330 are installed in the drawing, one is connected to the air curtain 170, and the other five is formed so that the blowing holes are inclined in steps of 10 degrees step by step to effectively blow to the conveying direction of coal. As a result of the increase of the firepower and induction of complete combustion, the air curtain 170 is provided at the fuel inlet inlet to control the discharge of dust generated during fuel supply and combustion to the outside through the inlet.

When the coal is burned while being transferred to the discharge position, the coal is burned and is left in the state of remaining coal ash. The fired block which is fastened to the chain of the chain conveyor 210 while being in contact with the grinding roller 410 provided at one side thereof ( When the 220 is returned, the large coal ash which is partially introduced or dropped into the space portion generated between each oven block 220 and does not flow therebetween is pinched between the grinding roller 410 and the oven block 220 built on one side thereof. When it is crushed and dropped to the bottom of the carbon ash transport path 420, it is transferred to one of the space portion 421 by a feed screw 430 installed in the carbon ash transport path 420.

And the coal ash collected in the one space portion 421 is a basket 520 is installed at a predetermined interval by the operation of the chain conveyor 510 is installed to be inclined so as to rise above the hopper 130, the basket 520 is collected When it is poured and poured into the upper outlet 530, the coal ash of the lump that is not passed through the sorting network 540 installed in the outlet 530 falls to the outside of the outlet and is put into the hopper 130 located below the outlet. The coal ash passing through the screening net 540 is discharged to the outside through the discharge line 531.

On the other hand, the thermal power generated by the combustion of coal on the furnace block 220 installed in the orbital form is raised upward, while the flue gas inflow passage 111 on one side while heating the water pipe 121 arranged up and down arranged on the combustion chamber 110 above. Hot air flows into the flue space 151 through a plurality of associations 153 that communicate with the flue gas inlet 111 and the flue space chamber 151 on the opposite side through the flue gas inlet 111 and passes through the tube 152 again to the year 140. It is emitted through the outside.

That is, the heat generated in the combustion chamber 110 is to pass through the tube (152.153) formed in the interior of the tank chamber 120 in a zigzag form to heat the tank chamber 120 formed around it by heat transfer.

As described above, the present invention induces the complete combustion by increasing the thermal power by the efficient supply arrangement of the blower while the combustion device performs a continuous combustion function in the orbital transfer, and also after pulverizing the burned carbon material to the appropriate size In the process of collecting and discharging, it is possible to separate and discharge the incompletely burned carbon material, which is more than the predetermined size, to re-enter the boiler, thereby maximizing the efficiency of the boiler and improving convenience.
