Abstract
A system for forming a hollow modular candle filter includes: a first filter portion having at least one open end; a hollow second filter portion having at least one open end; a sleeve configured to fit within the open end of the first filter portion and the open end of the second filter portion; and an adhesive configured to bind the sleeve to each of the first filter portion and the second filter portion.

Abstract
An inorganic fiber containing silica, alumina, one or more alkali metal oxides, and one or more of alkaline earth metal oxides, transition metal oxides, or lanthanide series metal oxides. The inorganic fiber exhibits good thermal performance at use temperatures of 1260°C and greater, retains mechanical integrity after exposure to the use temperatures, is free of crystalline silica upon devitrification, is alkali flux resistant, exhibits low bio-persistence in an acidic medium, and exhibits low dissolution in a neutral medium. Also provided are thermal insulation products incorporating the inorganic fibers, a method for preparing the inorganic fiber and a method of thermally insulating articles using thermal insulation prepared from the inorganic fibers.
