Patent ID: 7175681

Claim:
An apparatus which removes fine particles in exhaust gas exhausted from at least one of a diesel engine, a boiler and an incinerator, comprising: a housing formed of a non-magnetic material through which the exhaust gas passes; a coil which is wound around an outer peripheral section of the housing; a high-frequency power supply which is configured to supply a high-frequency current to the coil; and a collection device which is arranged in the housing and collects fine particles in the exhaust gas, wherein the collection device comprises a filter formed of sintered nonwoven fabric filter formed by sintering metallic fibers and configured to withstand a temperature of at least 600° C. and to trap the fine particles, and a support supporting the filter on the housing, and configured to allow the exhaust gas which has flowed in from one side to flow out from the other side, and wherein at least the filter generates heat with an eddy current induced therein when the high-frequency current is supplied to the coil to a temperature of at least 600° C. to burn the fine particles trapped by the filter.
