Radiant cell watertube boiler and method

摘要: A watertube boiler system is disclosed which provides a plurality of radiant burners mounted within housing in parallel, spaced-apart relationship. Individual are encircled by heat cells comprised coils tangential juxtaposed relationship achieving high view factor to the burner surfaces. Premixed fuel and air combusts on outer surfaces radiate energy tubes forming cells. The ratio combustion surface area cell volume an optimum range for minimizing NOX CO emissions.
