摘要： PURPOSE:To facilitate detection of a permeability, by measuring the suction speed of the raw material and by operating the permeability from differential pressure between pressure in the box and atmospheric pressure. CONSTITUTION:Wind box 16, anemometer 17, measuring cylinder 18, permeablity indicator 20, differential pressure generator 21, and so on are provided, and atmospheric air is sucked by wind box 16 provided for measurement of the permeability, and permeability P is obtained from suction air speed v and pressure loss DELTAp for passage of the suction wind through the raw material. That is, v is measured by the ultrasonic anemometer, and value Q obtained by multiplying v by sectional area S of the measuring cylinder becomes an airflow rate per a unit time. Difference between pressure in box 16 and atmospheric pressure is measured with the differential pressure generator to obtain DELTAp, and permeability P shown by expression I is calculated by the operator. By this method, stable detection of the permeability can be performed because the detecting unit is not brought into contact with the raw material.

摘要： PURPOSE:To control the evaporation amt. to an appropriate value with high responsiveness by controlling the change in the metal vapor deposition amt. in a vacuum deposition device with the shutter opening and heater power to rapidly change the shutter opening in accordance with the increase and decrease demands in the evaporation amt. CONSTITUTION:Band steel 7 is continuously conveyed by a rolling roller 11, the metal bath 1 of molten Zn, etc., in a metal path vessel 2 is heated by a heater 4, the obtained Zn vapor 3 is passed through a chamber 6, and the thin vapor-deposited film of Zn is formed on the surface of the band steel 7. When the vapor deposition amt. is increased, the heater power difference from the maximum heater power is obtained by an arithmetic unit 18, the difference is inputted to the opening adjusting device 15 for a shutter 8 to increase the opening of the shutter 8, the supply power to the heater 4 is simultaneously increased to increase the evaporation amt., and then the shutter opening is returned to the original value. When the vapor deposition amt. is decreased, the power of the heater 4 is reduced to a minimum to decrease the shutter opening, and then the shutter opening is returned to the original opening when the temp. of the metal bath 1 is lowered. Consequently, the metal vapor 3 is supplied on the surface of the band steel 7 in accordance with the change in the vapor deposition amt.

CONSTITUTION:The set value of the temp. of band steel 1 at the outlet of a cooler 3 is inputted to a temp. regulator 12. The cooling gas pressure in a plenum chamber 3a of the cooler 3 is set and controlled based on the output signal from the regulator 12 through a gas pressure regulator 13. The set value of the pressure of cooling gas in the chamber 3a against the set value of the temp. of the band steel 1 is determined through an arithmetic unit 15. The set value is inputted to the pressure regulator 13 to control the pressure of the cooling gas in the chamber 3a. The stability of the process in a vapor deposition chamber 5 is detected, and all the control is switched to the pressure control system when the process is unstable to control the temp. of the band steel 1.

摘要： PURPOSE:To enable the treatment of combustible gas in a hopper of the titled facility in high efficiency, by introducing an inert gas for the cooling of a circulation system of a main body into a coke-charging hopper while stepwise changing the flow rate, mixing with combustible gas in a hopper and burning the mixture in a catalytic reactor. CONSTITUTION:Coke 1 is charged into a coke-charging hopper 2. An inert gas 5 for cooling is taken out of a circulation system of a main body including a cooling chamber 6 and introduced into the hopper 2 at the first prescribed flow rate for a prescribed period. The mixed gas in the hopper 2 is taken out at the first prescribed flow rate. After the lapse of the above period and before the concentration of the combustible gas G in the hopper 2 decreases below a prescribed level, the flow rates of the cooling inert gas and the mixed gas are adjusted to the second prescribed flow rate corresponding to the concentration of the combustible gas after the lapse of the prescribed period. Thereafter, the rated treating amount of the inert gas and mixed gas is adjusted to decrease the concentration of the combustible gas in the hopper below a prescribed level and the mixed gas taken out of the system is mixed with air 33 and burnt in a catalytic reactor 32.

摘要： PURPOSE:To enable the charging of coke at a prescribed pitch, safely and easily, by detecting the amount of combustible gas in a coke-charging hopper and introducing an inert gas for cooling at a specific flow rate. CONSTITUTION:The charge of coke can be carried out safely and easily at a prescribed pitch by the following process. An inert gas 5 for cooling is introduced into the system during the period from the closure of a hopper door 3 after the charge of coke to a hopper 2 to the time when the concentration of the combustible gas in the hopper 2 reaches the peak. The amount of the inert gas (the second prescribed level) is adjusted to correspond with the first prescribed level and the peak level. At the same time, the mixed gas in the hopper 2 is taken out of the system at the second prescribed flow rate corresponding to the first level and the peak level. The flow of the inert gas can be controlled corresponding to the [peak level which has a relationship to the amount of generated combustible gas G and the concentration of the combustible gas G in the hopper 2 can be quickly decreased below a specific level.
