Abstract
Systems and methods for managing excess above-ground corn residue are disclosed. Systems and methods for combusting corn residue to produce heat for generating steam are also disclosed. Additionally, methods and systems for harvesting and pre-processing corn residue prior to combustion of the corn residue are disclosed.
Claims23
A method for managing excess above-ground corn residue and for generating steam, the method comprising:
- identifying a site location within a predetermined proximity to a high density of high-yield corn-on-corn acres;
- building a corn residue combustion and steam generation facility at the site location;
- contracting with corn growers within a service area of the site location for the right to harvest above-ground corn residue on the corn growers behalf, wherein the corn growers are growers of high yield corn-on-corn acres of corn;
- contracting with the corn growers for the right to store baled above-ground corn residue on the corn growers property;
- contracting with the corn growers to require the corn growers to provide notification of expected corn grain harvest dates and measured corn moisture contents;
- harvesting the above-ground corn residue on the corn growers behalf after the corn growers have harvested the corn grain, the above-ground corn residue being harvested when the above-ground corn residue has a moisture content in the range of 10 to 15 percent, and the harvesting including baling the above-ground corn residue in rectangular bales;
- storing bales on the corn grower's property;
- transporting the bales from the corn grower's property to a pre-processing station of the corn residue combustion and steam generation facility, wherein the bales are reduced at the pre-processing station to form reduced corn residue;
- combusting the reduced corn residue in a furnace at the corn residue combustion and steam generation facility to produce heat;
- and
- using the heat from the furnace to generate steam in a boiler.
