Heat generator useful as an auxiliary heating unit for a vehicle comprises a particulate filter or oxidation catalyst mounted immediately downstream of a burner

摘要

Particulate filter or oxidation catalyst arrangement for a heat generator comprises a particulate filter or oxidation catalyst mounted immediately downstream of a burner in a flue gas flow region. An independent claim is also included for purifying flue gas from a heat generator by passing the gas into a particulate filter or oxidation catalyst after cooling the gas to a temperature above the ignition temperature of soot or the activation temperature of the catalyst.
