Pre-burning, dry process methodology and systems for enhancing metallurgical solid fuel properties
First Claim
1. A method comprising:
- receiving a desired end condition of a solid fuel;
determining a duration and a power level of a microwave emission for each of a series of microwave generators based on the desired end condition; and
sequentially irradiating the solid fuel with the microwave emissions from the series of microwave generators at the determined power levels for the determined durations, thereby processing the solid fuel to the desired end condition, wherein said determining of the duration and the power level of the microwave emissions for each of the series of microwave generators is changed based on maintaining a measured solid fuel temperature not exceeding about 100 degrees Celsius during processing.

Abstract
Measurements are taken of moisture, BTU/lb (British Thermal Units per pound), ash, forms of sulfur, volatile material, grindability, and absorption properties of any of a wide variety of mine-run solid fuels. Using that information, a dry electromagnetic process technology has been developed that can be controlled and monitored to selectively alter and enhance metallurgical solid fuel properties. Specific changes include altering the mechanical structure and chemical composition of solid fuels such as coal, coal coke or petroleum coke, increasing the BTU/lb to optimum levels, decreasing all forms of sulfur, and decreasing ash, while maintaining the BTU/lb of the fuels. A new family of solid fuel designer coals not found in nature can be produced via these methods and apparatus.
