The present invention relates to a coke boiler, and in particular, the secondary protection pipe is provided in the fuel sensor, so as to minimize the high temperature adverse effect of the combustion furnace on the fuel sensor, and to ensure a stable and stable support, the water supply capacity of the tank and The present invention relates to a coke boiler that improves thermal efficiency and prevents damage to the roaster drive unit and the feeding screw to maximize the life of the device.

Coke is a porous solid granular material that removes volatiles from coal at high temperatures, and is relatively inexpensive and economical with high calorific value.It is known as a very good fuel such as no harmful gases and harmful substances during combustion. It is widely used as a fuel for boilers.

As shown in FIG. 1, the coke boiler of the prior art using such a coke as a fuel roll includes a water tank 110 including an inner water tank 111 and an outer water tank 112, and a combustion chamber C disposed under the inner water tank. , A roaster 120 in which coke, which is particulate fuel, is mounted and burned in the combustion chamber C, a feeding unit 130 including a hopper 131 and a feeding screw 132 for supplying fuel to the combustion chamber, and an ignition burner 140. And a fuel detection sensor 150.

In the coke boiler 100 having the above configuration, the coke 2, which is fuel, is supplied from the hopper of the feeding unit 130 to the roaster 130 through the feeding screw 132, and the particulate fuel is supplied to the roaster 130. A driving means 121 is provided to prevent the load from being unilaterally loaded on one side.

The fuel sensor 150 senses the remaining amount of fuel, and the driving of the feeding screw 132 is controlled by a signal according to the result to feed the coke into the combustion chamber.

The sensor 150 according to the related art is provided with a sensor 151 at an inner end thereof, and the sensor connecting rod 152 connected to the sensor 151 is covered with a heat resistant strong protective tube, and the sensor 151 ) And an insulating sleeve 154 is provided between the protective tube 153 and the outer end of the protective tube 153 is fixed to the outer water tank 112 side.

The fuel detection sensor 150 has a high temperature of about 1200 to 1800 ° C. in the installed combustion chamber C, and when the coke is injected or when the roaster 120 rotates, the coke collides with the fuel detection sensor 150 and is impacted. It is installed in the environment of bad condition.

As such, in the state where the strength is weakened at a high temperature, only one side is eccentrically supported as described above, and the other end portion is often subjected to the impact by coke, so that the fuel sensor 150 is sag inwardly, and the flow is generated. There was a problem in that the lifetime of an expensive fuel sensor is very short due to cracks and breakage occurring in the insulating sleeve 150.

In addition, the prior art has a problem that the water tank 111 is a funnel type to be inclined linearly, the water capacity is lowered and the heating efficiency is lowered.

In addition, the roaster 120 is installed at a position spaced apart from the bottom of the outer tank 112, such that the bending portion is generated in the shaft 121 of the roaster due to the high temperature, or the bearing 123 is fixed. There was a problem.

In addition, the feeding screw 132 of the feeding part is rotated in only one direction, so that coke powder and agglomerate are stuck in the feeding pipe 133 to make a rigid wall, so that the screw is damaged by the wall. there was.

The present invention has been devised to solve the above problems,

The purpose of the present invention is to minimize the adverse effects of the high temperature of the combustion furnace on the fuel sensor by providing a secondary protective tube in the fuel sensor, and to ensure the solid and stable support of the fuel sensor to maximize the life of the device To provide a coke boiler.

Another object of the present invention is to provide a coke boiler in which the lower portion of the inner tank is formed in a hemispherical shape so that the water capacity and the thermal efficiency are improved.

Still another object of the present invention is to provide a coke boiler for improving the life of the drive unit and smooth operation of the device by cooling the heat applied to the roaster drive unit by extending the outer water tank below the roaster.

Still another object of the present invention is to provide a coke boiler which prevents coking powder from sticking in the feeding pipe by preventing the feed screw from being rotated forward / reversely.
