Abstract
A refractory tile adapted for protective fixation to the heat exchanger in an incinerator or furnace regardless of orientation. The tile includes a transverse groove which carries a shouldered slot to be guided by and mate securely with an anchor attached to the heat exchanger.
Claims5
A refractory tile adapted for fixation to a heat exchanger to produce, with other tile, a protective covering for said heat exchanger, each of said tile comprising
- an exposed face;
- a concealed face;
- and
- an edge spacing said faces apart;
- said concealed face carrying at least one groove open to said concealed face and extending transversely from said edge, said groove including a terminated slot having a shoulder with an underside, wherein the underside begins with a guiding surface tapered into said groove toward said exposed face and ends with a securing surface paralleling said groove;
- whereby said groove is thusly adapted to guide the tile into position and mat the tile securely with at least one anchor mounted on said heat exchanger.
A refractory tile system comprising
- (a) a tile which includes
- an exposed face;
- a concealed face;
- and
- an edge spacing said faces apart;
- said concealed face carrying at least one groove open to said concealed face and extending transversely from said edge, said groove including a terminated slot having a shoulder with an underside, wherein the underside begins with a guiding surface tapered into said groove toward said exposed face and ends with a securing surface paralleling said groove;
- in combination with
- (b) at least one T-shaped tile anchor having a stem sized to pass along said slot and to be mounted on said heat exchanger, together with a bar to engage said shoulder.
A protective covering for a heat exchanger comprising a plurality of refractory tile systems, each comprising
- (a) a tile which includes
- an exposed face;
- a concealed face;
- and
- an edge spacing said faces apart;
- said concealed face carrying at least one groove open to said concealed face and extending transversely from said edge, said groove including a terminated slot having a shoulder with an underside, wherein the underside begins with a guiding surface tapered into said groove toward said exposed face and ends with a securing surface paralleling said groove;
- in combination with
- (b) at least one T-shaped tile anchor having a stem sized to pass along said slot and to be mounted on said heat exchanger, together with a bar to engage said shoulder.
