下する。2. Description of the Related Art In order to gasify pulverized coal and other carbonaceous solids by pyrolysis, collect the gas, and use it as an energy source, equipment for coal gasification has conventionally been used. In this facility, raw materials such as pulverized coal are charged into a gasification furnace, supplied with an oxygen-containing gas and high-temperature steam to partially burn and thermally decompose, and the generated gas is recovered by this pyrolysis. is there. In such a coal gasifier, when the gasification reaction is performed, the inorganic components contained in the raw material such as pulverized coal are melted, and the molten slag flows down the furnace wall.

It has been proposed to provide a slag tap at the lower part of the gasification furnace, allow molten slag to flow down from the slag tap, granulate with a slag cooling hopper, and discharge the granulated slag outside the system. It has been proposed that the cooling water be circulated in order to avoid mixing into the generated gas due to temperature rise and evaporation.

動を中断させるという問題があった。However, in such a gasification furnace, when a gasification reaction is performed, part of the pulverized coal or other carbonaceous substances to be gasified by thermal decomposition is not gasified and is opened at the lower part of the gasification furnace. The slag tap falls into the slag cooling hopper. Pulverized coal or carbonaceous solids that have once undergone a high-temperature heat history have a very low bulk density and are hydrophobic, and therefore float on the surface of the cooling water. Further, the molten slag flowing down is stirred by the drop impact, mixed with the cooling water, and becomes a foamy floating substance (hereinafter referred to as scum) floating on the cooling water surface. In an extreme case, the scum grows on the surface of the water, reaches the slag tap, closes the slag tap, and the slag melts to cool the slag tap, solidifying near the slag tap, causing an operation failure. was there. These scums are frequently generated when the temperature in the gasification furnace is low at the time of starting the gasification furnace, and there is a problem that the start of the gasification furnace is interrupted.

た。In a slag cooling hopper that circulates cooling water, the scum can be discharged together with the cooling water from a drain port opened near the surface of the cooling water, but the scum is floating on the water surface. For this reason, the gas generated in the gasification furnace must be discharged together with the generated gas, and a large amount of the gas generated in the gasification furnace leaks from the air opening of the cooling water distribution system.

用である。Next, the operation method of this embodiment will be described. During operation of the gasification facility, the cooling water is guided to the cooling water tank 8 through the communication pipe 7-2 along with the scum through the communication port 7-1 opened near the surface of the cooling water. The cooling water guided to the cooling water tank 8 is drained through a drain port 9 provided in the cooling water tank 8. By operating so that the cooling water tank 8 does not become empty, the scum stays only in the cooling water tank 8, does not stay in the slag cooling hopper 2 and does not hinder the operation of the gasification facility, and In addition, the gas generated in the gasifier 1 does not leak. From the cooling water discharge port 9 provided in the cooling water tank 8, only the cooling water not containing the scum can be obtained. When the fluidity of the scum is poor or the amount of generated scum is large, it is also useful to provide the connecting pipe 7-2 with an inclination.
