Particle trap apparatus and methods

摘要

A method for removing particulate matter from an exhaust stream, in which the exhaust stream is passed through a particle trap assembly. The trap assembly includes a particle trap having a trap inlet, a filter region located downstream from the trap inlet, and an upstream portion located upstream from the filter region. The cross-sectional area of the upstream portion is preferably at least as great as the cross-sectional area of the filter region. The particle trap may be operably coupled directly to a source of an exhaust stream via a connector unit. The trap assembly may include a heating unit for heating at least a portion of the trap assembly, and a bellows-like connector unit.
