摘要： The flow of waste gas is directed downwardly by means of a refractory guide chute so as to follow the down flow of molten slag at the downstream end of a slag outlet. Thus the sensible heat of the high-temperature waste gas forcedly heats the molten slag and the downstream end portion of the slag outlet. Consequently, it becomes less possible for the slag outlet to be choked up. When there are signs that the slag outlet is being choked up, the plasma torch is slightly tilted to the upstream end of the slag outlet so as to stabilize the discharge of the molten slag. A housing or jacket is disposed circumferentially around an incineration residue feed pipe, inserted through the incineration residue inlet, and adapted to allow an annular gas curtain to issue therefrom. Fuel injection against the waste gas in the furnace body is particularly suitable for decreasing the amount of NOx. Valuable matter is efficiently recovered from the waste gas without causing a waste gas channel in a waste gas purifying plant to be choked up with the particles of valuable matter. A device for detecting the leakage of cooling water caused by the deterioration of the plasma torch is also provided.

摘要翻译： 废气的流动通过耐火材料导向槽向下引导，以便跟随炉渣出口下游端的熔渣的下流。 因此，高温废气的显热强制地加热熔渣和炉渣出口的下游端部分。 因此，排渣口被堵塞变得不太可能。 当有迹象表明炉渣出口被堵塞时，等离子体炬稍微倾斜到炉渣出口的上游端，以稳定熔渣的排放。 围绕焚化残渣进料管围绕焚化残渣入口设置的壳体或护套，并且适于允许从其中发出环形气帘。 对炉体中废气的燃料喷射特别适用于减少NOx的量。 贵重物质从废气中有效地回收，而不会使废气净化设备中的废气通道被有价值物质的颗粒堵塞。 还提供了用于检测由等离子体焰炬劣化引起的冷却水泄漏的装置。
