The furnace is operated for a certain period of time with the oxygen in the exhaust gas from the coal partial combustion furnace 1 reduced to drops, and the nitrogen gas passage 41 and the solenoid valve 42 are introduced from the nitrogen gas holder 40 into the dead space shown by the dashed line in FIG. A branch passage 43a having
Nitrogen gas is blown through ~43k to fill the system with inert gas. Once the system is sufficiently filled with inert gas, the fuel (pulverized coal) supplied to the coal partial combustion furnace 1 is gradually increased, the air ratio is lowered, the combustible gas concentration is increased, and the gas generation process is started. to go into. In the gas generation process, oxygen holder 1 is used to adjust the calorie content of the generated gas.
3 supplies oxygen to the duct 2 to enrich the combustion air with oxygen and increase calories. In this way, the system can be started up safely by gradually replacing inert gas with flammable gas and preventing the generation of dangerous combustion or explosive gases.

Operate for a certain period of time at air ratios i and o, and blow nitrogen gas into the dead space shown by the dashed line in the system as described above to replace the gas in the system with an inert gas and create a sufficient tampon layer. After it has formed, the fuel is completely squeezed out and replaced with air.

In order to prevent this, nitrogen gas is forcibly blown into the outlet of the coal partial combustion furnace 1 on the upstream side of each gas in the system and into the dead space in the system to dilute the combustible gas in the system. In order to prevent the generation of gas in the explosion range and to quickly discharge some of the gas in the system to the outside of the system, the first gas dispersion chimney 30 side of the four-way valve 27 is opened, and the duct 24' side and the circulation path are opened. 29 side is closed and the gas is dissipated into the normal atmosphere of combustion at the top of the first gas dissipation chimney 30.
