Abstract
An improved filter candle is provided for filtering entrained particulate matter from hot gasses. The filter candle is constructed ceramic fibers bonded together into a porous unitary tubular mask having a bottom end and an annular flange at the top end. The top and bottom ends of the filter have substantially higher density than the tubular mid-section of the filter and as a result, the strength of the end portions of the filter is enhanced, and the ends are therefore less susceptible to damage.
