Abstract

The artificial embers can generally be used in any gas appliance with a gas fired log set that has a burner and are formed of silicon carbide or alumina. A plurality of the embers are placed loosely on a burner in registry with the flames of the burner in order to produce a simulation of actual glowing embers. The plurality of glowing embers simulates an actual ash bed or coals within the gas fired log set. The glowing artificial embers release a minimal amount of NO 2 and CO emissions while creating a more realistic and brighter glow.

Claims (57)

1 . An artificial ember for use in a gas fireplace comprising:

at least one burner having a plurality of gas ports disposed within a gas fireplace;

a valve assembly in fluid communication with said at least one burner;

a pilot in fluid communication with said valve assembly;

at least one artificial log positioned above said at least one burner;

a mat member formed of a material selected from the group consisting of silicon carbide, alumina and combinations thereof, wherein a plurality of said mat members disposed over said plurality of gas ports;

each said mat member having a density of about 0.12 g/cm 3 ; and

each said mat member having a thickness of about 0.007 inches.

2 . The artificial ember as in claim 1 wherein each said mat member comprises a plurality of fibers, wherein each said fiber has a diameter of about 10 to about 30 microns.

3 . The artificial ember as in claim 2 wherein said plurality of fibers welded together.

4 . The artificial ember as in claim 1 wherein each said mat member being square in shape of about 1 inch to about 1.125 inches on a side.

5 . The artificial ember as in claim 1 wherein each said mat member weigh about 0.0214 kg/m 2 .

6 . The artificial ember as in claim 1 wherein said gas fireplace is vent free.

7 . A synthetic ember bed for use on a burner comprising:

a burner having a plurality of gas ports disposed within a gas fireplace;

at least one artificial log positioned above said burner;

a valve assembly in fluid communication with said burner;

a pilot in fluid communication with said valve assembly;

a mat member formed of a plurality of fibers, wherein a plurality of said mat members disposed over said plurality of gas ports;

each said fiber having a diameter of about 10 to about 30 microns;

said mat member having a density of about 0.12 g/cm 3 ; and wherein

said plurality of fibers are of a material selected from the group consisting of silicon carbide, alumina and mixtures thereof.

8 . The synthetic ember bed as in claim 7 wherein said mat member having a square shape of about 1 inch to about 1.125 inches on a side.

9 . The synthetic ember bed as in claim 7 wherein said mat member having a thickness of about 0.007 inches.

10 . The synthetic ember bed as in claim 7 wherein said mat member has a weight of about 0.0214 kg/m 2 .

11 . The synthetic ember bed as in claim 7 wherein said gas fireplace is vent free.

12 . A synthetic ash bed for use in a gas fireplace comprising:

a burner having a plurality of gas ports disposed within a gas fireplace;

at least one artificial log positioned above said burner;

a valve assembly in fluid communication with said burner;

a pilot in fluid communication with said valve assembly;

a plurality of artificial embers;

each said ember being formed of a plurality of fibers, each said ember formed of a material selected from the group consisting of silicon carbide, alumina and combinations thereof, wherein said plurality of artificial embers scattered loosely over said plurality of gas ports; and

each said ember having a density of about 0.12 g/cm 3 .

13 . The synthetic ash bed as in claim 12 wherein each said fiber having a diameter of about 10 to about 30 microns.

14 . The synthetic ash bed as in claim 12 wherein said plurality of fibers welded together forming said ember.

15 . The synthetic ash bed as in claim 12 wherein each said ember comprises a square of about 1 inch to about 1.125 inches on a side.

16 . The synthetic ash bed as in claim 12 wherein each said ember having a thickness of about 0.007 inches.

17 . The synthetic ash bed as in claim 12 wherein each said ember has a weight of about 0.0214 kg/m 2 .

18 . The synthetic ash bed as in claim 12 wherein said gas fireplace is vent free.

19 . A method of creating an artificial ember for a gas fireplace comprising the steps of:

cutting a mat structure into a square shape to create at least one first artificial ember having a first thickness, said square shape is about 1 inch to about 1.125 inches on a side; and

manually separating each said first artificial ember of said first thickness into at least one second artificial ember of a second thickness, wherein said second thickness is about 0.007 inches.

20 . The method of creating an artificial ember as in claim 19 wherein manually separating each said first artificial ember into said at least one second artificial ember is conducted by a knife.

21 . The method of creating an artificial ember as in claim 19 wherein said mat structure formed of a material selected from the group consisting of silicon carbide, alumina and combinations thereof.

22 . The method of creating an artificial ember as in claim 19 wherein each said second artificial ember having a density of about 0.12 g/cm 3 .

23 . The method of creating an artificial ember as in claim 19 wherein said mat member comprises a plurality of fibers, wherein each fiber has a diameter from about 10 to about 30 microns.

24 . A method of simulating a natural glowing ash bed for a gas fireplace comprising the steps of:

having a gas fireplace comprising of at least one burner and a pilot in fluid communication with a valve assembly;

positioning at least one artificial ember loosely over said at least one gas port of said at least one burner, each said artificial ember has a thickness of about 0.007 inches and a density of 0.12 g/cm 3 , each said artificial ember is formed of a material selected from the group consisting of silicon carbide, alumina and combinations thereof,

generating a flame from at least one gas port of said at least one burner; and

simulating a portion of a glowing ash bed when said flame engages said at least one artificial ember.

25 . The method of simulating a natural glowing ash bed as in claim 24 wherein said gas fireplace is vent free.

26 . The method of simulating a natural glowing ash bed as in claim 24 further comprising the step of maintaining the aesthetics of each said flame when engaging each said ember.

27 . The method of simulating a natural glowing ash bed as in claim 24 wherein each said artificial ember having a square shape of about 1 inch to about 1.125 inches on a side.

28 . The method of simulating a natural glowing ash bed as in claim 24 wherein each said artificial ember comprises a plurality of fibers, wherein each fiber has a diameter from about 10 to about 30 microns.

29 . The method of simulating a natural glowing ash bed as in claim 24 further comprising the step of placing a plurality of said at least one ember intermittently over a plurality of said gas ports to simulate said glowing ash bed.
