Claims: I claim:

1. An apparatus for lining a wall of a furnace and like equipment, comprising:

a. a folded ceramic fiber blanket having a fold formed in a central portion thereof and having two end portions thereof folded together and extending from said fold for insulating the furnace;

b. a support beam mounted extending along the length of said fold in said folded blanket, said folded end portions of said folded blanket also extending inwardly from said support beam to assist in insulating said support beam;

c. a suspension arm having said support beam mounted therewith at a position on said support beam within said fold in said folded blanket;

d. said suspension arm extending from an inner end portion in said fold through said central portion of said folded blanket to an outer end portion;

e. an attachment beam for mounting with the wall of the furnace, said attachment beam having a mounting orifice formed therein;

f. said suspension arm further having a mounting lug, formed at said outer end portion thereof, inserted into said mounting orifice in said attachment beam for attaching said folded blanket and said suspension arm to said attachment beam; and

g. said attachment beam further having connecting openings formed therein for passage of connecting members therethrough to attach said attachment beam to the wall of the furnace wherein said folded blanket forms an insulating lining for the wall of the furnace.

2. The apparatus of claim 1, wherein a plurality of mounting orifices are formed in said attachment beam and further including:

a. a plurality of folded ceramic fiber blankets, each having a fold formed in a central portion thereof and having two folded end portions thereof folded together and extending from said fold for insulating the furnace;

b. a plurality of support beams, each mounted extending along the length of said fold in one of said folded blankets, said folded end portions of each of said folded blankets also extending inwardly from one of said support beams to assist in insulating said support beams;

c. a plurality of suspension arms, each having one of said support beams mounted therewith within a fold of one of said folded blankets, and extending therethrough; and

d. each of said plurality of suspension arms having a mounting lug therewith inserted into one of said plurality of mounting orifices in said attachment beam.

3. The apparatus of claim 1, wherein said support beam comprises:

a support beam mounted extending within said fold along a substantial portion of the length thereof to provide increased support for said folded blanket.

4. The structure of claim 1, wherein said support beam comprises:

a ceramic support beam.

5. The structure of claim 1, wherein said support beam comprises:

a high temperature-resistant metal beam.

6. The structure of claim 1, further including:

an insulating pad mounted between said folded blanket and said attachment beam and having an opening therein for passage of said suspension arm therethrough.

7. The apparatus of claim 1, wherein plural apparatus are mounted with the furnace wall to line the furnace wall and wherein said attachment beam of each of said plural apparatus further includes:

an attachment pin and an attachment receptacle formed at opposite ends of said attachment beam for connecting said attachment beam to adjacent attachment beams.

8. An apparatus for lining a wall of a furnace and like equipment, comprising:

a. a folded ceramic fiber blanket having a fold formed in a central portion thereof and having two end portions thereof folded together, said folded end portions extending from said fold for insulating the furnace and being held in compression to reduce vitrification and shrinkage of said blanket;

b. a support beam mounted extending along the length of said fold in said folded blanket;

c. a suspension arm having said support beam mounted therewith at a position on said support beam within said fold in said folded blanket;

d. said suspension arm extending from an inner end portion in said fold through said central portion of said folded blanket to an outer end portion;

e. an attachment beam for mounting with the wall of the furnace, said attachment beam having a mounting orifice formed therein;

f. said suspension arm further having a mounting lug, formed at said outer end portion thereof, inserted into said mounting orifice in said attachment beam for attaching said folded blanket and said suspension arm to said attachment beam; and

g. said attachment beam further having connecting openings formed therein for passage of connecting members therethrough to attach said attachment beam to the wall of the furnace wherein said folded blanket forms an insulating lining for the wall of the furnace.
