[Prior art] When charging coal in a coke oven, the total coal loading amount (wet base) is calculated from the volume of the coking chamber, the moisture content of the coal, and the particle size. The value is determined by dividing the amount of coal by the number of coal ports and is adjusted based on the experience and intuition of the driver of the coal loading vehicle.For example, if the total amount of coal charging is 42T and the number of coal ports is 4, both ends of the coking chamber Assuming the furnace wall temperature of the coal charging port sections at both ends, the furnace wall temperature of the coal charging port sections at both ends is lower than the target temperature because the heat dissipation amount is larger in the coal charging port sections at both ends than in the center section. 107 in each of the two coal charging ports at both ends.
, 11T was distributed and charged to each of the two central coal charging ports. [Problem to be solved by the invention] Conventionally, the distribution of coal charging amount based on the operator's experience is not necessarily ideal in the temperature distribution in the furnace length direction, and there are variations from furnace to furnace, resulting in poor fire-off and heat consumption. There was a problem in that it led to an increase in [Means for Solving the Problems] This invention attempts to solve the above-mentioned problems by measuring the furnace wall temperature of the coke oven carbonization chamber, calculating the average temperature of each compartment using a calculator, This coke oven coaling method is characterized by correcting the amount of coal in each section based on the difference from the target temperature of each section input in advance. [Function] In this invention, the temperature of the furnace wall of the carbonization chamber, which is measured by a thermometer attached to the ram head of the extruder, is measured by a computer. The average temperature of each section is determined by a computer. Then, it compares and calculates the amount of coal in each section (each port) by comparing and calculating the amount of coal in each section inputted in advance, and issues a command to the hopper scale device of the coal loading car.In other words, in each section, The amount of carbonization is based on the actual furnace wall temperature of the coke oven. [Example] An example of the present invention will be described in detail below. Fig. 4 is a cross-sectional view of the coke oven carbonization chamber, and Fig. 3 1 is a diagram showing the ram head of an extruder equipped with a radiation thermometer. 1 is a carbonization chamber, C

3.24 is the coal charging port, which will be referred to as the 1st coal charging port, the 1st coal charging port, the 1st coal charging port, the 1st coal charging port, the 1st coal charging port, and the 2nd coal charging port. Coal from the coal charging port is charged into the sections indicated by broken lines below each coal charging port (referred to as Nal section, NL2 section, etc.). 2 is the ram, 3 is the ram head, 41, 42 and 43 are radiation thermometers attached to the ram head 3, which in turn are an upper thermometer, a middle thermometer, and a lower thermometer, and they measure the temperature at the top, middle, and bottom of the furnace wall when extruding coke from the coking chamber. 1rg is a block diagram of the method of the present invention. When coke is discharged from the carbonization chamber 1 by the extruder, the radiation thermometer 4 installed in the ram head 3 measures the temperature on and inside the furnace wall. The temperature of the lower stage is measured.The measured temperature is transmitted to the central computing device (or computing machine) 5 by induction radio or wireless.
The following deduction is performed in the arithmetic unit 5. ■Calculate the average value of the furnace N temperature in each compartment, and calculate the correction coefficient for the coal charging amount in each compartment based on the difference between this average temperature and the pre-input target temperature for each compartment. ■Calculate the temporary loading amount for each section from the bulk density of coal, moisture content, and volume of the coking chamber that are input separately, and calculate the actual loading amount by multiplying by the correction coefficient in ■. The coal is sent to the automatic coal loading device of the coal loading car, and is charged into each carbonization chamber from each charging port 21, 22, 23. will stop automatically. Figure 2 is a graph showing the measured temperature distribution in the carbonization chamber and the target temperature for each section. In the figure, A is the target temperature of each section, and B is the temperature measured with a radiation thermometer installed in the extruder ram head. In Fig. 2, in the NIL1 section, the target temperature is 1000°C, but the actual average temperature is 970°C. The charging amount in this case is calculated as follows.
If the temporary loading amount for one target section is 10.57, the correction coefficient is (1000-970)/1000=0.03, so the mounting loading amount = 10.5 x O. 97=10.187.
In the NIL2 section, the measured average temperature is lower than the target temperature, so a negative correction is made, and in the Seed 3 and 4 sections, the measured average temperature is higher than the target temperature, so a positive correction is made. The target temperature in Figure 2 is set higher on the CS side than on the PS side because a draft slope is provided toward the CS side to make it easier to discharge coke into the carbonization chamber. Compartment volume is CS
This is because it gets larger towards the sides. When the method of the present invention was implemented, there were no partial fire failures,
A reduction of 10,000 Kcal/T was achieved in unit heat consumption. [Effects of the Invention] The present invention actually measures the furnace wall temperature of the coking chamber with a thermometer installed in the ram head, and calculates and charges the amount of coal in each compartment based on the measured value. Partial excess or deficiency in the amount of coal charged and poor fire-off are eliminated, and the effect is that the unit heat consumption can be reduced compared to conventional methods.
