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. Assuming that the upstream end of the slag outlet is disposed at a horizontal distance of L from the downstream end of a waste inlet, a pivot, about which a plasma torch is tilted, is disposed at a horizontal distance of 0.2L to 0.45L from the downstream end of the waste inlet. Because of this arrangement, heat from a plasma arc is adapted to be radiated to the downstream end of the waste inlet and its vicinity so as to quickly melt the waste. 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. A driving device for changing the inclination of the jacket is provided, this driving device being associated with a tilting device for changing the inclination of the plasma torch so that, when the inclination of the plasma torch is changed by the tilting device, the inclination of the jacket may also be changed by the driving device. Gas, e.g. air, is delivered from the jacket and directed toward a reservoir of the molten slag in such a manner that the direction of radiation from the plasma torch and the direction of gas delivery from the jacket intersect substantially on the surface of the slag reservoir. Thus the incineration residue is allowed to fall onto a high-temperature area of the surface of the slag reservoir. 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： PROBLEM TO BE SOLVED: To stabilize the temperature of gas and to prevent melting of a device by stabilizing an arc. SOLUTION: An arc holding part 2 is placed between an anode part 1 and a cathode part (5), and as gas is made to flow from one anode part 1 to the other cathode part via the arc holding part 2, it is heated by an arc 20 produced by the electrode parts 1, (5) to obtain an ultra-high-temperature gas. The other cathode part into which the gas flows from the arc holding part 2 has a cathode chamber 18 having a greater bore than the arc holding part 2. The arc holding part 2 side wall surface of the cathode chamber 18 is set at an inclination angle θ whereby the gas flowing in is made to advance along the wall surface.

摘要： PURPOSE: To use high temperature and high pressure gases required at a reforming process as power, and improve durability as well as an availability factor by concurrently using a combustion plasma and the oxygen enriched air for enabling reforming reaction to be applied via the non-catalytic partial combustion method. CONSTITUTION: Fuel gases, steam, the oxygen enriched air and H2 circulation gases are respectively supplied to a reformer 1. A spark plug 7 is ignited immediately before the completion of the compression stroke of the reformer 1, and oxygen-hydrogen mixed gases in a precombustion chamber 5 flow into a main combustion chamber 4, while burning. As a result, gas temperature in the chamber 4 rises and water-fuel mixed gases start a reforming reaction process. Then, a combustion plasma is generated with a plasma electrode 30 at expansion stroke, thereby compensating for gas activity. A part of exhaust gases from a fuel cell 2 flows to the reformer 1, and the rest is burnt in a combustor 42, together with exhaust gases of the oxygen enriched air, thereby rotating a turbine 22 and operating a generator 27.
