がある。As described above, the interior of the high-temperature and high-pressure vessel b of the coal gasifier a has a high temperature, and the interior of the high-temperature high-pressure vessel b has a capacity of about 2 to increase the gasification capacity.
The pressure is as high as 0 kgf / cm 2 . On the other hand, the cooling water circulation system e only circulates cooling water necessary for cooling, and its internal pressure is lower than the internal pressure of the high-temperature high-pressure vessel b, such as about 5 to 10 kgf / cm 2 . Therefore, if the jacket d in the high-temperature and high-pressure container b is broken, the high-pressure gas in the high-temperature and high-pressure container b is discharged by the cooling water circulation system e.
In addition, there is a possibility that the cooling water circulation system e may be damaged at a stretch and a large amount of leaks may occur. For this reason, it is conceivable to increase the pressure of the cooling water in the cooling water circulation system e to substantially the same pressure as the internal pressure of the high-temperature and high-pressure vessel b to reduce gas leakage and cooling water leakage. It is necessary to increase the size and to improve the pressure resistance of the piping g on the water supply / drain side of the jacket, which has the disadvantage of increasing costs and energy.

Will be. However,
If the burner jacket is damaged and a hole is opened, the internal pressure of the cooling water circulation system is lower than the internal pressure of the high temperature and high pressure vessel,
The high-pressure gas in the high-temperature high-pressure vessel starts flowing to the cooling water circulation system,
The flow rate of the cooling water flowing through the cooling water circulation system fluctuates. Then, the pressure equalizing system switching means detects this, and supplies high-pressure cooling water from the cooling water equalizing system to the cooling water circulating system to raise the pressure of the cooling water circulating system to approximately the same pressure as the internal pressure of the high-temperature and high-pressure vessel. The pressure equalization between the pressure of the cooling water circulating system and the internal pressure of the high-temperature and high-pressure container is detected by the pressure detecting means to detect the internal pressure of the high-temperature and high-pressure container and the pressure at the outlet of the jacket, and supplied into the jacket by the equalizing means controlled by the detection signal. This is achieved by adjusting the flow rate of the cooling water pressure. Therefore, when the pressure of the cooling water circulating system and the internal pressure of the high-temperature and high-pressure container are substantially the same, gas in the high-temperature and high-pressure container flows into the cooling water circulating system, and the cooling water of the cooling water circulating system leaks into the high-temperature and high-pressure container. It is possible to minimize the amount of rubbing.

It switches to 26 and flows. After the cooling water flowing through the bypass pipe 26 passes through the bypass shutoff valve 27 of the pressure equalizing means 12, the flow rate and the pressure are adjusted by the pressure equalizing system flow rate adjusting valve 28. That is, the pressure of the cooling water flowing through the cooling water circulating system 7 is increased by the pressure equalizing system flow control valve 28 controlled by the pressure detecting means 11 and the pressure in the high-temperature and high-pressure vessel 2 and in the jacket drainage pipe 13 of the cooling water circulating system 7. The pressure will be adjusted to be substantially the same.

達成される。As described above, according to the present invention, the jacket 4 of the burner 3 is damaged and a hole is opened, the high-pressure gas in the high-temperature and high-pressure vessel 2 flows into the cooling water circulation system 7, and the flow rate of the cooling water flowing through the cooling water circulation system 7 varies. In this case, the pressure equalizing system switching means 10 detects this, and supplies high-pressure cooling water from the cooling water equalizing system 9 to the cooling water circulating system 7 to increase the pressure of the cooling water circulating system 7 and to detect the pressure. 11 detects the pressure in the high-temperature and high-pressure vessel 2 and the pressure on the outlet side of the jacket 4 to control the pressure equalizing means 12 and adjusts the flow rate of the cooling water pressure supplied into the jacket 4 to thereby control the pressure in the high-temperature and high-pressure vessel 2 and the jacket. By making the pressure on the outlet side approximately the same, the amount of the high-pressure gas in the high-temperature and high-pressure vessel 2 flowing into the cooling water circulating system 7 and the amount of the cooling water in the cooling water circulating system 7 leaking into the high-temperature and high-pressure vessel 2 can be determined. Just keep it low The ability. Therefore, even if the burner jacket of the high-temperature and high-pressure container is damaged and a hole is opened, a large amount of high-pressure gas flows into the device and destroys the device, or conversely, a large amount of cooling water in the device becomes hot. It is possible to prevent double accidents, such as the flow in the high-pressure vessel and the continuation of operation becomes impossible, thereby improving the reliability and safety of the device.

Even if the burner jacket of the high-temperature and high-pressure container is damaged and a hole is opened, a large amount of high-pressure gas flows into the device and destroys the device, etc. Conversely, a large amount of cooling water in the device flows into the high-temperature and high-pressure container. As a result, it is possible to prevent a double accident such as continuation of operation becomes impossible, and to achieve an excellent effect of improving the reliability and safety of the device.
