Abstract
A combustion system comprises a discharge nozzle with concentric air and fuel orifices. A fuel conduit is coupled to each fuel orifice while an air conduit is coupled to each air orifice. The fuel and air only mixing with one another upon discharge. A supplemental air source supplies supplement air for combustion. An air deflector disk supports the discharge nozzle and a cylindrical blast tube surrounds the air deflector sleeve and the air deflector disk while an outlet end of the cylindrical blast tube supports a flame retention head. The deflector disk permits some combustion air to flow into the combustion chamber while redirecting a remaining portion of the supplement air. The flame retention head permits some of the supplement air to discharge into a burner box while redirecting the remaining supplement air radially inward through openings in the air deflector sleeve to assist with combustion of the fuel mixture.
