Abstract: A combustion enhancing member employed with a stoker combustion system is disposed on the grate of the stoker and includes at least one chamber. The chamber has at least one fluid inlet for receiving a combustion enhancing fluid and a plurality of fluid outlets for distributing the fluid to the bed of fuel moving along the grate of a stoker combustion system, thereby increasing the burning efficiency of the stoker.

Abstract: A combustion enhancement system with in-bed foils are utilized to enhance combustion and emissions. The combustion enhancement system is especially designed for use in a traveling grate-type stoker in which the combustion foils are positioned on the top surface of the grate such that the fuel is moved past the foils by the grate. The combustion foils are provided with a high pressure fluid, such as a gas, to be injected into the fuel. The combustion foils are shaped to divide the fuel such as to create turbulence within the fuel. Preferably, the fluid is injected into the fuel at the point of turbulence.
