Abstract: A regenerative thermal oxidizer (RTO) is constructed to receive polluted waste gases from an industrial process, cleanse the gas and permit cleansed gas to exit the RTO to the environment.  The RTO includes a lower section having an inlet to receive polluted or incoming gas, and a centrally positioned rotary distributor in the lower section for cooperation in controlling gas flow via a segmented center section.  The rotary distributor is substantially smaller than the lower section and is of a substantially smaller cross section.  Incoming gas is directed to a middle section segment(s), fills the segment(s) and then flows through a peripheral opening to a segmented upper section where it passes through a heat exchanger to a combustion chamber where it is oxidized or cleansed.  From there cleansed gas passes through another upper section segment through a heat exchanger and back to center section segment(s).  In the center section the cleansed gas flows to the rotary distributor where it is divided into outgoing and purge gases.  The outgoing gas flows through the rotor to a manifold and then to an outlet.  The purge gas flows through a purge segment in the rotor to a center discharge pipe.  From the pipe the purge gas is directed to a conduit for exiting the RTO and the purge gas is then recycled to the incoming gas to the RTO.

Title: High power dc blocking device for ac and fault current grounding
Inventor: PELLY BRIAN R
IPC: H02H7/16
Filed: 1996-08-12
Granted: 2000-10-24
Abstract: A high power DC blocking device is provided which blocks DC current, passes AC current, and limits the voltage across it under fault conditions. A DC blocking capacitor is used to block the flow of DC current, while allowing the passage of normal AC currents. A main bypass path includes switching devices which provide a low impedance path across the capacitor under fault conditions. Auxiliary switching devices are used to connect a storage capacitor across the device at the initiation of a fault, thereby charging the storage capacitor to a stored voltage level before the main switching devices are fired. After the fault passes, the auxiliary switching devices are fired once again to apply the stored voltage in the storage capacitor to the main switching devices to commutate them off. The storage capacitor and auxiliary switching devices also form part of a voltage clamp circuit which dissipates inductive energy stored in a system to which the DC blocking device is connected. Multiple backup firing circuits are provided which activate the low impedance bypass path in the event of failure of the main firing circuits or of the blocking device control system. The effectiveness of the DC blocking device is continuously monitored using a DC current sensing circuit which is capable of distinguishing small DC currents in the presence of large AC currents.

Abstract: A porous carbonaceous material that can adsorb large quantities of nitrogen, oxygen, carbon dioxide and methane is produced in a high yield by a process which comprises the step of halogenating carbonized coal by contact with a halogen gas to yield halogenated carbonized coal and the step of dehalogenating the halogenated coal to eliminate part or all of the halogen atoms therefrom. When this material is used for preparing an electric double-layer capacitor, the obtained capacitor has a larger electrostatic capacity than those prepared from other carbonaceous materials. Thus it is possible to produce a carbonaceous material having micropores and/or submicropores suitable for adsorbing small molecules of nitrogen or the like and storing electrochemical energies.
