Publication number: 20220373172Abstract: Refractory tile for protecting a wall of energy recovery tubes. A hot face of the tile is to be exposed to the interior of the furnace. A cold face, opposite the hot face, defines: a groove extending over the entire length of the tile and to receive one the tubes, and a fastening receptacle configured to receive a retaining member to immobilize the tile with respect to the tube. The tile has, in a transverse section plane, at least at each position between the position of the groove and the position of the fastening receptacle, a non-zero material thickness. The thickness is measured between the transverse profile of the hot face and a straight segment, which is referred to as the base and links the ends of the transverse profile of the hot face. The positions are determined along the base.Type: ApplicationFiled: October 23, 2020Publication date: November 24, 2022Inventors: Laurie SAN-MIGUEL, Sébastien PINSON, Keith MANN, Benedikt FISCHER, Denis PFUETZE

Publication number: 20140374938Abstract: Disclosed is a process for producing ceramic particles, such as proppants, that have at least 10 percent total porosity. The process includes forming a particle precursor that includes 5 percent to 30 percent of a first ceramic material and at least 40 percent of a second ceramic material. The sintering temperature of the first ceramic material may be lower than the sintering temperature of a second ceramic material. Heating the precursor to a maximum temperature above the sintering temperature of the first material and below the sintering temperature of the second material. Also disclosed is a ceramic article that has a particular combination of chemistry and alumina crystalline phase.Type: ApplicationFiled: June 25, 2013Publication date: December 25, 2014Inventors: Tihana FUSS, Laurie San-Miguel, Kevin R. Dickson, Walter T. Stephens
