ABSTRACT:
A furnace structure has a particle separator for separating a mixture of a transport fluid and pulverized coal into a coarse coal fraction and a fine coal fraction, a furnace, a burner assembly for burning the pulverized coal, and a windbox for providing combustion supporting gas to the burner assembly. The burner assembly has separate, concentrically disposed elements to burn coarse and fine coal particles under different combustion conditions to reduce the production of nitrogen oxides from the combustion of coal as a fuel. The burner assembly further includes a control nozzle for maintaining a swirling motion in the combustion flame and a separate, axially-movable adjustable sleeve for regulating the quantity flow of turbulence-free combustion-supporting air.
