Abstract
A high temperature, abrasion resistant insulating module is described having a sinuously folded, ceramic blanket with a lath covering three side of the folded blanket. The lath has doubled back portions extending into the folds of the blanket on it hot face. To the lathed front face of the folded blanket is applied a layer of thermally stable, abrasive resistant material which not only serves an as abrasion shield to the brittle fibrous material of the blanket, but only serves to stabilize the module and to reduce fiber dust.
Claims21
An insulating block comprising:
- a. an insulating layer,
- b. a hot face having an anchor means associated therewith, where the anchor means includes portions extending into the insulating layer and secured therein by a fastener extending through the insulating layer and engaging the extending portions of the anchor means;
- c. a cold face having a mount associated therewith;
- d. four side faces;
- and
- e. a hard layer anchored to the hot face by lockingly encasing a portion of the anchor means associated with the hot face, where the hard layer imparts a desired property to the hot face of the block.

A composite block comprising:
- a. a first block including:
- i. a first block insulating layer,
- ii. a first block hot face having a first anchor means associated therewith, where the anchor means includes portions extending into the insulating layer and secured therein by a fastener extending through the insulating layer and engaging a portion of the first anchor means;
- iii. a first block cold face having a mount associated therewith;
- iv. four first block side faces;
- and
- b. a second block including:
- i. a second block insulating layer,
- ii. a second block hot face having a second anchor means associated therewith, where the second anchor means includes portions extending into the insulating layer and secured therein by a fastener extending through the insulating layer and engaging a portion of the second anchor means;
- iii. a second block cold face having a third anchor means associated therewith, where the third anchor means includes portions extending into the insulating layer and secured therein by a fastener extending through the insulating layer and engaging a portion of the third anchor means;
- iv. four second block side faces;
- c. a bonding layer interposed between the first block hot face and the second block cold face which lockingly engages a portion of the first and third anchor means;
- and
- d. a hard layer anchored to the second block hot face by lockingly encasing a portion of the second anchor means associated with the second block hot face, where the layer imparts a desired property to the second block hot face.
