The slagging panel 12 is installed on the inner wall surface of the furnace 11 of the boiler and an air flow path through which the air supplied from the air supply part 30 circulates is provided inside the slagging panel 12 13 may be formed.

For example, the slagging panel 12 may be formed in various shapes such as a substantially rectangular plate shape, a rectangular tube shape, a cylindrical shape, or a semi-cylindrical shape.

During the combustion and gasification of the solid fuel in the furnace 11 of the boiler, the reaction occurs. At this time, the generated slag is classified as under slag, slag and non-slag.

Therefore, the slagging measurement method according to the preferred embodiment of the present invention includes installing a slagging panel 12 on the inner wall of the furnace 11 of the boiler, and measuring the viscosity of the slag flowing down the wall surface of the furnace 11 of the boiler .

3, the first temperature sensor 51 of the temperature sensing unit 50 installed on the slagging panel 12 senses the temperature of the slagging panel 12. [

The temperature sensing unit 50 transmits the temperature of the slagging panel 12 sensed by the first temperature sensing sensor 51 to the control unit 70.

The control unit 70 compares the sensed temperature sensed by the first temperature sensor 51 with a predetermined reference temperature for melting the slag adhering to the inner wall surface of the furnace 11 of the boiler S12.

If the sensed temperature is lower than the reference temperature in step S12, the control unit 70 heats the air supplied to the air passage 13 of the slagging panel 12 from the air supply unit 30, The operation of the air heating portion 40 and the flow rate regulating portion 60 is controlled (S14).

That is, the air supply unit 30 drives the pump or the blower according to the control signal of the control unit 70 to pressurize the air to a predetermined pressure to supply the air to the heating unit 40, and the air heating unit 40, 41) to heat the air.

The flow rate regulator 60 increases the opening amount of the air supply line 14 to increase the flow rate of the air supplied to the air flow path 13 of the slagging panel 12.

The heated air is supplied to the air flow path 13 of the slagging panel 12 through the air supply line 14 and is subjected to heat exchange with the slagging panel 12 in the course of moving along the air flow path 13 To heat the slagging panel (12).

As the slagging panel 12 is heated and the temperature rises, the slag adhering to the wall surface of the furnace 11 of the boiler melts and flows.

Through the heating process of the slagging panel 12, if the detected temperature is higher than the reference temperature as a result of the comparison in the step S12, the controller 70 determines that the slag is sufficiently melted and is in a state of being able to flow.

Thus, the control unit 70 measures the viscosity of the slag and controls the driving of the slagging measuring unit 20 so as to measure the slag behavior characteristics.

Accordingly, the slagging measuring unit 20 measures the slag behavior characteristics by measuring the viscosity of the slag flowing through the probe installed at one side of the furnace 11 of the boiler (S16).

At this time, the control unit 70 controls the operation of the heating unit 40 and the flow rate control unit 60 so as to maintain the temperature of the heating air constant and reduce the supply flow rate of the heated air (S18).

To this end, the second temperature sensor 52 senses the temperature of the heated air heated by the heating unit 40, and the temperature sensing unit 50 transmits a sensing signal to the controller 70.

The control unit 70 controls the driving of the heater 41 provided in the heating unit 40 so that the temperature of the heating air is kept constant according to the detection signal.

The controller 70 controls the operation of the mass flow controller provided in the flow controller 60 so as to gradually reduce the supply flow rate of the heated air to a preset minimum flow rate.

In step S20, the controller 70 checks whether the slagging measurement operation is completed, and controls the steps S10 to S20 to be repeated until the slagging measurement operation is completed.

If the slagging measurement operation is completed in step S20, the controller 70 stops driving the slagging measurement apparatus 10 and terminates the operation.

Through the above process, the present invention can precisely measure the behavior characteristics of the slag by supplying heated air to the slagging panel to melt the slag adhering to the furnace wall surface of the boiler.

Although the invention made by the present inventors has been described concretely with reference to the above embodiments, the present invention is not limited to the above embodiments, and it goes without saying that various changes can be made without departing from the gist of the present invention.

The present invention is applied to a technique for measuring the behavior characteristics of slag by supplying heated air to the slagging panel to melt the slag adhering to the furnace wall surface of the boiler.
