Abstract: An asphaltic polyurethane or isocyanurate foam (12) useful in roofing applications. The foam is made from asphalt having a penetration range of between approximately 5-25, a softening point of between approximately 120 .degree.F and 200 .degree.F, and an asphaltene content of no more than about 30 %. This asphalt is liquified and mixed with a mixture of polyols such as Voranol 270, Multranol 9138, and castor oil. Other chemicals, such as a surfactant, a viscosity reducer, and a flame retardant can also be included in this mixture. The mixture is then brought to a temperature of between approximately 140 .degree.F and 220 .degree.F, mixed with water and a polyisocyanate in a molar ratio of polyisocyanate:polyol of between about 0.95:1 and about 1.3:1, and reacted t o form an asphaltic polyurethane foam. Alternatively, a molar ratio of polyisocyanate:polyol of between about 2.0:1 and about 2.7:1 can be used. In this case, an asphaltic isocyanurate foam is produced.

Title: Plasma furnace and a method of operating the same
Inventor: YAMADA MOTOO
IPC: C03B5/26
Filed: 1994-03-08
Granted: 2000-10-24
Abstract: 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.
