ABSTRACT:
A cartridge boiler designed for use in multiples in a furnace, each cartridge boiler having a vertically oriented cylindrical drum top and bottom with hemispherical end caps, with a plurality of free-expansion boiler tubes having internal feed water supply tubes depending in a cluster through the bottom end cap. The supply tubes are gravity fed by an open feed water pan within the drum, the feed water supply being controlled by a boiler level monitoring device. The boilers are used in multiples to generate the steam required, the relative small size of individual cartridge boiler being designed to minimize fabrication costs by minimizing drum diameters, and maximize system performance by allowing select cartridge replacement without system shutdown.
