Abstract
A combustion furnace having a cylindrical filter arranged to pass gases between a combustion cylinder and a gas analyzer attached to an output port on the furnace. The gases to be analyzed are generated from a sample burned in the combustion cylinder and removed through the filter. A cleaning gas supply port and supply line for supplying a cleaning gas to the inside of the furnace are provided. The cleaning gas is under pressure and may be oscillated to assist in the removal of dust stuck to the filter and the interior of the furnace. The improved dust removal provides for a much cleaner furnace and a more accurate analysis of the sample.
