Abstract: A package water tube boiler having a novel radiant tube design which includes one or more additional tubes situated within the combustion section of the boiler. The novel tube design may be used in both hot water and steam applications.
Abstract: A package multiple pass flexible water tube boiler having staggered tubes that are substantially identical in length. The staggered tube arrangement, along with the inclusion of a plurality of baffles, optimizes heat transfer and minimizes the footprint of the unit.
Abstract: Embodiments of a high temperature fluid generator are adapted to heat a fluid to a high temperature using a heat source. The generator employs a forced circulation counter flow design including a furnace section, a convection section and a pair of L-shaped headers connected to tubes in the furnace and convection sections. In various embodiments, the headers are positioned on diagonally opposite corners and convection tubes are positioned at least partially outside of a flue path for the combustion gas.
Abstract: A package multiple pass flexible water tube boiler for converting water to steam. The boiler having an enclosure and diagonally offset upper and lower drums. The drums are connected by a series of staggered or offset water tubes. The water tubes comprise two sets of repeating tubes that are bent to substantially similar but not identical designs. The staggered tube arrangement optimizes heat transfer and minimizes the footprint of the unit.
