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.
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.
F22B 21/08 - Water-tube boilers of vertical or steeply-inclined type, i.e. the water-tube sets being arranged vertically or substantially vertically built-up from substantially-straight water tubes involving a single upper drum and a single lower drum, e.g. the drums being arranged transversely the water tubes being arranged sectionally in groups or in banks, e.g. bent over at their ends
F22B 37/12 - Forms of water tubes, e.g. of varying cross-section
F24H 1/40 - Water heaters other than continuous-flow or water-storage heaters, e.g. water heaters for central heating with water tube or tubes
F22B 21/22 - Water-tube boilers of vertical or steeply-inclined type, i.e. the water-tube sets being arranged vertically or substantially vertically built-up from water tubes of form other than straight or substantially straight

Multiple pass flexible water tube boiler and method of using same
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.
F22B 21/10 - Water-tube boilers of vertical or steeply-inclined type, i.e. the water-tube sets being arranged vertically or substantially vertically built-up from substantially-straight water tubes involving a single upper drum and a single lower drum, e.g. the drums being arranged transversely the water tubes being arranged in staggered rows
F22B 21/22 - Water-tube boilers of vertical or steeply-inclined type, i.e. the water-tube sets being arranged vertically or substantially vertically built-up from water tubes of form other than straight or substantially straight
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.
F22B 21/04 - Water-tube boilers of vertical or steeply-inclined type, i.e. the water-tube sets being arranged vertically or substantially vertically built-up from substantially-straight water tubes involving a single upper drum and a single lower drum, e.g. the drums being arranged transversely
F22B 21/10 - Water-tube boilers of vertical or steeply-inclined type, i.e. the water-tube sets being arranged vertically or substantially vertically built-up from substantially-straight water tubes involving a single upper drum and a single lower drum, e.g. the drums being arranged transversely the water tubes being arranged in staggered rows
F22B 19/00 - Water-tube boilers of combined horizontally-inclined type and vertical type, i.e. water-tube boilers of horizontally-inclined type having auxiliary water-tube sets in vertical or substantially-vertical arrangement
F22B 21/24 - Water-tube boilers of vertical or steeply-inclined type, i.e. the water-tube sets being arranged vertically or substantially vertically built-up from water tubes of form other than straight or substantially straight bent in serpentine or sinuous form
F22B 21/34 - Water-tube boilers of vertical or steeply-inclined type, i.e. the water-tube sets being arranged vertically or substantially vertically built-up from water tubes grouped in panel form surrounding the combustion chamber, i.e. radiation boilers
F22B 21/08 - Water-tube boilers of vertical or steeply-inclined type, i.e. the water-tube sets being arranged vertically or substantially vertically built-up from substantially-straight water tubes involving a single upper drum and a single lower drum, e.g. the drums being arranged transversely the water tubes being arranged sectionally in groups or in banks, e.g. bent over at their ends

Package boiler having steam generating units in tandem
A natural circulation water tube package boiler is assembled in a factory in two self-contained steam generating units. The first unit has a combustion chamber, but no convection tubes. The second unit has convection tubes, but no combustion chamber. Each unit has a mud drum, a steam drum, and tubes connecting the drums. Each steam generating unit is transported separately by truck or railcar to the operating site, where the rear end of the first unit is connected to the front end of the second unit by a large connecting duct; the mud drums of the respective units are connected to each other by water piping; the steam drums of the respective units are connected to each other by water piping and steam piping located above and below the waterline respectively; and the steam drum of the second unit is connected to the water drum of the first unit by water piping. The two steam generating units operate in tandem, with combustion gases flowing through the full width of both units serially, and out the rear of the second unit.
F22B 15/00 - Water-tube boilers of horizontal type, i.e. the water-tube sets being arranged horizontally
F22B 25/00 - Water-tube boilers built-up from sets of water tubes with internally-arranged flue tubes, or fire tubes, extending through the water tubes
