摘要： PURPOSE: To reduce total cnsumption of heat energy by controlling coal supply on the basis of an oven temperature pattern of a combustion chamber which minimizes heat load variation of the oven and total consumption of heat energy.
CONSTITUTION: A target burning temperature of coal is calculated from aimed carbonization time and required quality of coke. A fixed oven temperature value of a combustion chamber in operation under heating is determined from charging conditions and aimed burning temperature and two or more standard oven temperature values Uo including the above oven temperature value are selected. A combustion chamber oven temperature pattern is obtained by convergence calculation for each Uo value by use of a temperature increment calculation block and an oven temperature pattern calculation block, and a standard oven temperature value at which total consumption of heat energy is minimized is taken as an optimum standard oven temprature value. Then an optimum oven temperature pattern is calculated using the optimum standard oven temperature value and it is taken as an oven temperature pattern for operation. The control of coke oven heating is performed by controlling the amount of heat supply on the basis of difference between the target oven temperature and actually measured oven temperature at each time.

摘要： PURPOSE:To carry out oven temperature control with high accuracy, by preseting a feed fuel flow rate pattern in a feed forward control system on the basis of the operation results of a coke oven and correcting the pattern in a feedback control system for every dry distillation cycle. CONSTITUTION:An oven temperature pattern to be preset is determined on the basis of oven operating conditions and input data in step 1, a fuel-flow rate pattern corresponding to the above pattern is determined on the basis of the relationship between oven temperature and fuel flow rate obtd. from the actual data in the past in step 2, the resulting value is preset as the required preset value and an operation is commenced. The temp. DELTAt of a coke oven is measured at regular intervals, and a difference DELTAthetaf(t) between a preset oven temp. thetaref(t) at that time t and the measured oven temp. theta'f(t) obtd. by subjecting the measured oven temp. thetaf(t) to signal processing and the corrected value DELTAV(t) of the fuel flow rate corresponding to the difference DELTAthetaf(t) is determined in step 3. In step 4, the corrected fuel flow rate Vset(t) is determined by adding DELTAV(t) to Vref(t) to preset the value in a fuel flow rate control system, and the whole cycle is repeated in the subsequent dry distillation cycle.

摘要： PURPOSE: To produce high-quality coke particularly excellent in hot strength, by improving the temp. hysteresis of coal in a carbonization process in a coke oven.
CONSTITUTION: High-quality coke is produced by keeping a temp. increasing rate ≥5°C/min during fusion of coal in the carbonization of the coal in a coke oven. Since hot strength of coke is proportional to a temp. when it is pushed out of the coke oven as well as to a temp. increasing rate during the fusion, it is possible to largely increase hot strength of the coke by keeping the temp. increasing rate as described above.

摘要： PURPOSE:To increase the productivity of the blast furnace and reduce fuel ratio by measuring the temperature change of the furnace wall in the height direction of the blast furnace, detecting the position of fusion band root part in the furnace from its tendency pattern and controlling said position most adequately. CONSTITUTION:Thermocouple thermometers 811-816 are mounted in the staves 7b in the bosh part, barrel part and shaft part of a blast furnace 1 and are connected to a computer 10. The measured values of the thermometers are read in the computer 10 at every 2 minutes interval and the mean values T1-T6 thereof corresponding to the respective thermocouples are obtained at every one hour and 20 minutes. The position where the fusion band root part 5a in the blast furnace exists is detected from the pattern of these values with time. Thereby, the position and shape of the fusion band 5 are controlled most adequately to control the ventilation characteristic and gas utilization rate of the in-furnace gas most efficiently and maintain the conditions of the blast furnace in the finest state. Hence, the productivity and fuel cost of blast furnace are improved.
