Type:
Unique low NOx coal burner with center air jet for use with overfire air (OFA) systems.
Design features:
Developed exclusively for use with OFA systems for the lowest NOx emissions. Designed to accelerate coal ignition and intensify combustion for very rapid achievement of fuel rich conditions in the burner zone - the key to minimizing NOx emissions. Secondary air is drawn from the windbox to produce an axial air jet, which is surrounded by the coal stream. The coal stream is, in turn, surrounded by two air zones. This "inside-out / outside-in" ignition and combustion of the coal produces a very stable, intense flame. Ceramic materials provide long wear life for the core pipe and coal nozzle. A one-piece shop-assembled burner facilitates quality and simplifies installation. In retrofit applications, generally plugs into existing wall openings.
NOx removal efficiencies:
Compared to other advanced low NOx burners in use with OFA, the AireJet burner further reduces NOx by up to 30% with lower excess air for improved boiler efficiency.
