Abstract
A corrosion resistant refractory ceramic hexagonal target tile body for use covering a catalyst, including a generally flat hexagonal portion and a plurality of generally right circular cylindrical aperture portions extending therethrough, wherein the hexagonal tile body has a thickness of about 89 mm and a width of about 42 cm and is 13 percent yttria fully stabilized YSZ. Each respective aperture has a diameter of about 19 mm.

A generally hexagonal ceramic tile body, comprising:
- a flat hexagonal top surface;
- an oppositely disposed flat hexagonal bottom surface oriented parallel with the flat hexagonal top surface;
- a refractory material defining a refractory inner volume disposed between the top and bottom surfaces;
- and
- a plurality of apertures extending therethrough;
- wherein the refractory inner volume is between about 80 mm and 95 mm thick;
- wherein the flat hexagonal top surface is about 42 cm across;
- and
- wherein the refractory inner volume is fully stabilized yttria stabilized zirconia;
- and wherein the refractory inner volume contains between 8 percent and 16 percent yttria.
A corrosion resistant refractory ceramic hexagonal target tile body for use covering a burner media bed, comprising a generally flat hexagonal portion and a plurality of generally right circular cylindrical aperture portions extending therethrough;
- wherein the ceramic hexagonal target tile body has a thickness of about 89 mm and a width of about 42 cm;
- wherein the ceramic body is 13 percent yttria fully stabilized YSZ;
- wherein each respective aperture has a diameter of about 19 mm.
A method of retarding corrosion of burner catalyst media, comprising:
- a) positioning a plurality of catalyst media in a regenerative unit to define a bed;
- b) positioning a plurality of hexagonal target tiles adjacent the bed and between a hot gas source and the bed to define a contiguous floor;
- c) flowing hot gas through the contiguous floor and through the bed;
- wherein each respective hexagonal target tile has a thickness of about 89 mm, a width of about 42 cm, and a composition of 13 percent Atria fully stabilized YSZ.
