Abstract
An exhaust system for a combustion system, comprising a storage device for collecting NO.sub.x, hydrocarbon, or particulate emissions, or mixture of these emissions, and a plasma reactor for destroying the collected emissions is described. After the emission is collected in by the storage device for a period of time, the emission is then destroyed in a non-thermal plasma generated by the plasma reactor. With respect to the direction of flow of the exhaust stream, the storage device must be located before the terminus of the plasma reactor, and it may be located wholly before, overlap with, or be contained within the plasma reactor.
Claims10
An exhaust system for a combustion process, comprising:
- (a) a storage device with means for collecting from an exhaust stream at least one member selected from the group consisting of hydrocarbon, particulate, and NO.sub.x emissions, and mixtures thereof;
- (b) a plasma reactor capable of generating a non-thermal plasma;
- and
- (c) means for alternating between collection of the emissions in the storage device and destruction of the collected emissions in the plasma reactor,
- wherein, with respect to the direction of flow of the exhaust stream, the storage device is located before the terminus of the plasma reactor.
