Abstract

PURPOSE:To provide the titled apparatus equipped with a slag hole which is easily replaceable and easy to practice maintenance and inspection, by providing a slag hole which is replaceable from the bottom of a gasifying oven and which incorporates a coil for cooling water in the portion facing the oven and a heater in the inside face of the hollow. CONSTITUTION:The ash component contained in a coal is molten in a high-temp. atmosphere and flows through a slag hole 13 into an ash hopper 14 provided at the bottom. A cooling water 15 is fed in the ash hopper 14, and the slag is quenched to form a granulated slag 16 which is discharged outside the system. The slag hole 13 has a detachable structure and can be detached and mounted through a manhole 17 provided in the ash hopper 14 and a manhole provided on the wall of an autoclave 10 located at the outside thereof. A coal 18 is fed in a slightly upper portion of a coal-char nozzle 9a of a gasifying oven 9 to conduct a gasifying reaction. The formed gas 19 is taken out of the top of the gasifying oven 9 and led to systems for dust collection and desulfurization.

2. Prior Art Conventional slag discharge device of this type of gasifier 22064
This is disclosed in Japanese Patent Application No. 90, in which a spiral (coiled electrical resistance heating element 4
(Figs. 7 and 8) or a vertically spiral coiled electric resistance heating element 4' (Figs. 9 and 10) is embedded to prevent the slag tap 3 from clogging when the load is reduced. However, this method has the following drawbacks.

(2) When the load is high and the temperature inside the furnace is sufficiently high, there is a high risk that the electric resistance heating element 4 will burn out in a short period of time (very unreliable).

■、炉底部の耐火断熱材としてのスラグタップ3自身も
高温下にさらされるので、寿命が短かくなり易い。
(2) The slag tap 3 itself, which serves as a refractory heat insulating material at the bottom of the furnace, is also exposed to high temperatures, which tends to shorten its life.

■In an entrained bed gasifier, it is essentially necessary to maintain the temperature inside the furnace at a substantially constant temperature above the melting temperature of ash over the entire normal operating load range. In some cases, they allow the temperature inside the furnace to drop, even though they fear that the ash will no longer melt, and they only propose solutions that involve only partial measures.

On the other hand, another conventional example shown in FIG.
This method is disclosed in Japanese Patent No. 2986, in which the slag tap 3 is used as a molded brick, the outer periphery of the molded brick is wrapped with a heat insulating concrete 5, and the slag tap 3 is poured into the heat insulating concrete 5.
By embedding the water-cooled inductance coil 6,
A frequency is applied to heat the slag tap 3 made of molded bricks by induction.

Therefore, in this conventional example, the heating to the slag tap 3 is as follows.
Since this is an indirect method in which heat is transferred from the insulating concrete-embedded coil 6 to the molded bricks, the responsiveness of temperature adjustment during load fluctuations during gasification operation is not necessarily good. Moreover, since the water tank 7 is installed and the cooling water stored there is used, the structure around the slag tap 3 becomes complicated. Furthermore, stopping the cooling water will cause coil burnout, so it is necessary to take measures to prevent water outages.
