た。In the coal pyrolysis method according to the method disclosed in Japanese Patent Laid-Open No. 5-295371, the temperature in the pyrolysis furnace, which is a pyrolysis condition, is the temperature and the amount of gas in the gasification furnace, and the pyrolysis. It depends on the amount of coal. Therefore, if the operating conditions (temperature, gasification amount, oxygen amount, steam input amount) of the gasification furnace are changed, the temperature of the pyrolysis furnace also changes. From the slag outlet at the bottom of the gasifier, the ash contained in the coal or char that is put into the gasifier is discharged as molten slag, but the molten slag may solidify and adhere at the slag outlet. Therefore, it is necessary to increase the amount of oxygen introduced into the gasification furnace in order to remove the attached slag and raise the temperature near the slag discharge port. At that time, there was a problem that the temperature and composition of the high-temperature gasification gas generated from the gasification furnace were changed, the temperature of the pyrolysis furnace was changed, and the product properties were not stable.

増加させれば良い。BEST MODE FOR CARRYING OUT THE INVENTION Most of the slag produced in the gasification furnace is collected as molten slag on the wall surface of the gasification furnace and discharged from the slag discharge port on the bottom of the gasification furnace to the outside of the system. When the slag solidifies and adheres to the slag discharge port, the temperature in the lower part of the gasification furnace may be increased from 1200 ° C to 1700 ° C.
To raise the temperature of the lower part of the gasification furnace, there is a method of increasing the amount of oxygen charged in the gasification furnace or decreasing the amount of water vapor. However, in these methods, the properties and the amount of the high-temperature gasification gas generated from the gasification furnace change, which affects the thermal decomposition reaction. Therefore, in the present invention, according to the amount of steam input from the gasification burner input port of the gasification furnace,
Adjust the amount of steam input from the steam inlet. As a specific mode of adjustment, the temperature of the lower part of the gasification furnace is raised by reducing the amount of steam fed from the gasification burner, and a substantially equal amount of the reduced steam is fed from the steam inlet. By doing so, it was found that the amount of gas, the temperature and the composition generated from the gasifier hardly changed, and the operation could be performed without affecting the thermal decomposition reaction. In addition,
In the present specification, a gasification burner is a fuel for a gasification furnace,
It means a device that inputs oxygen and water vapor. Also,
After solidification / adhesion of slag at the slag discharge port is resolved,
It is necessary to lower the temperature of the lower part of the gasification furnace to protect the walls of the gasification furnace. For that purpose, the amount of water vapor from the water vapor inlet may be reduced and the amount of water vapor introduced from the gasification burner may be increased by approximately the same amount.

Under the condition (condition 1) in which the entire amount of the input steam is supplied from the burner, the difference between the gasifier upper temperature and the gasifier lower temperature is about 50 ° C. Under these conditions, the slag occasionally solidifies and forms deposits at the slag outlet.
