Abstract

A system for the combustion of high solids liquid to produce steam for the production of ethanol is disclosed. The system comprises a method for combusting high solids liquid. The method comprises supplying a stream of high solids liquid to a furnace; atomizing the stream of high solids liquid into the furnace; and distributing biomass fuel into the furnace. The stream of high solids liquid are combusted with the biomass fuel in the furnace.

First claim

What is claimed is:

1. A method for combusting a high solids liquid, comprising:
supplying a stream of high solids liquid to a stoker grate boiler, wherein the stream of high solids liquid is atomized to form an atomized stream of high solids liquid; and
distributing biomass into the stoker grate boiler;
wherein the atomized stream of high solids liquid is combusted in suspension above the biomass in the stoker grate boiler.

2. The method of claim 1 , wherein the atomizing comprises employing one or more nozzles.

3. The method of claim 2 , wherein the atomizing further comprises using an atomization fluid.

4. The method of claim 3 , wherein the atomization fluid comprises compressed air.

5. The method of claim 4 , wherein the one or more nozzles are positioned in a horizontal configuration.

6. The method of claim 5 , wherein the one or more nozzles create a spray pattern and the spray pattern is a fan type pattern.

7. The method of claim 6 , wherein the one or more nozzles comprise at least one flat fan nozzle.

8. The method of claim 7 , wherein the nozzle pressure is within the range of 30 to 100 pound-force per square inch gauge, inclusive.

9. The method of claim 8 , further comprising selectively altering the rate at which the atomized high solids liquid is supplied.

10. The method of claim 4 , wherein the one or more nozzles are positioned in a vertical configuration.

11. The method of claim 10 , wherein the one or more nozzles create a spray pattern and the spray pattern is a fan type pattern.

12. The method of claim 11 , wherein the one or more nozzles comprise at least one flat fan nozzle.

13. The method of claim 12 , wherein the nozzle pressure is within the range of 30 to 100 pound-force per square inch gauge, inclusive.

14. The method of claim 13 , further comprising selectively altering the rate at which the atomized high solids liquid is supplied.

15. The method of claim 3 , wherein the atomization fluid comprises steam.

16. The method of claim 15 , wherein the one or more nozzles are positioned in a horizontal configuration.

17. The method of claim 16 , wherein the one or more nozzles create a spray pattern and the spray pattern is a fan type pattern.

18. The method of claim 17 , wherein the one or more nozzles comprise at least one flat fan nozzle.

19. The method of claim 18 , further comprising selectively altering the rate at which the atomized stream high solids liquid is supplied.

20. The method of claim 15 , wherein the one or more nozzles are positioned in a vertical configuration.

21. The method of claim 20 , wherein the one or more nozzles create a spray pattern and the spray pattern is a fan type pattern.

22. The method of claim 21 , wherein the one or more nozzles comprise at least one flat fan nozzle.

23. The method of claim 22 , further comprising selectively altering the rate at which the atomized stream of high solids liquid is supplied.

24. The method of claim 1 , wherein the high solids liquid comprises syrup produced at an ethanol plant that produces ethanol from corn starch.

25. The method of claim 1 , wherein the high solids liquid comprises syrup produced at a biorefinery that converts lignocellulosic biomass into ethanol.

26. The method of claim 1 , wherein the biomass is selected from at least one member of the group consisting of corn cobs, corn stover, fiber from corn kernels, switchgrass, farm residue, agricultural residue, wood chips and other wood waste.
