Abstract
According to embodiments, a co-fired or multiple fuel combustion system is configured to apply an electric field to a combustion region corresponding to a second fuel that normally suffers from poor combustion and/or high sooting. Application of an AC voltage to the combustion region was found to increase the extent of combustion and significantly reduce soot evolved from the second fuel.
Claims13
A method for operating a combustion system, comprising:
- outputting a first fuel and a first oxidant;
- supporting a first combustion reaction with the first fuel and first oxidant;
- supporting a second combustion reaction of a heated second fuel to produce a flue gas including entrained particles;
- providing an electrical charge to the second combustion reaction, wherein the electrical charge is carried by the entrained particles;
- supporting a first field electrode adjacent to a main flow of the flue gas;
- applying a first voltage to the first field electrode;
- and
- electrostatically attracting the entrained particles toward the first field electrode to remove at least a portion of the entrained particles from a main flow of the flue gas.
