<P>PROBLEM TO BE SOLVED: To provide an improved combustion furnace for analysis capable of more excellently cleaning a filter and a tube. <P>SOLUTION: An automatic cleaning assembly for an analytic furnace is removable from a filter chamber above a combustion tube. The cleaning assembly has a rotary brush, and the rotary brush is moved down through the filter chamber and put into the combustion tube while being vacuumed through a lower seal of the combustion tube. Thus, a more vacuum pressure difference for removing dust from the filter and the combustion tube of the furnace can be obtained and a flow rate therefor is improved. <P>COPYRIGHT: (C)2012,JPO&INPIT |
