ABSTRACT:
A particle reduction apparatus comprises a radiation absorption zone for receiving a gaseous flow carrying particulate matter. A transparent shield surrounds at least a portion of the radiation absorption zone. A radiation source for generating radiation and for directing the radiation into the radiation absorption zone to promote reduction of the particulate matter is provided, and an insulation layer at least partially surrounds the radiation source.
