ABSTRACT:
An exhaust filter system for filtering a creosote component from exhaust gases of a combustion chamber burning wood, primarily for use with airtight wood burning stoves, comprises an airtight filter apparatus arranged between a combustion chamber outlet for the exhaust gases and a flue for removing the filter exhaust gases. The filter includes a gas distributing chamber in communication with the combustion chamber outlet and receiving hot exhaust gases therefrom and a gas collecting chamber in communication with the flue and delivering filtered exhaust gases thereto. A heat exchange unit airtightly connects the gas distributing and collecting chambers. The unit defines a vertical flow path for the exhaust gases and is capable of cooling the gases to a temperature range wherein the creosote component present in the hot exhaust gases in vaporized form is condensed to a liquid. A sump is mounted to receive the condensed liquid by gravity from the heat exchange unit. The filter apparatus is arranged to provide a thermally induced, natural draft for the exhaust gases from the combustion chamber outlet to the flue.
