A superheated steam boiler includes an inner tank system including a wet tank and a dry tank separated by an isolation member, an outer sleeve surrounding the inner tank system, wherein wet tank fluid openings allow the wet tank to be in communication with the outer sleeve, and dry tank steam openings in the dry tank allow the dry tank to be in communication with the outer sleeve, and a burner system within the inner tank system. The burner system includes a combustion/expansion chamber having spherical surfaces located in and fluidly isolated from the wet tank, a distribution chamber located in and fluidly isolated from the dry tank, heat tubes extending through the isolation member between the combustion/expansion chamber and the distribution chamber; and an exhaust tube extending from the distribution chamber and out of the inner tank system to exit the boiler.

Provided is a superheated steam boiler. The superheated steam boiler, in this embodiment, includes an inner tank system, the inner tank system including a first wet tank and a second dry tank separated from one another by an isolation member, an outer sleeve at least partially surrounding the inner tank system, wherein one or more wet tank fluid openings proximate a lower surface of the first wet tank allow the first wet tank to be in fluid communication with the outer sleeve, and further wherein one or more dry tank steam openings in the second dry tank allow the second dry tank to be in steam communication with the outer sleeve, and a burner system located primarily within the inner tank system. The burner system, in this embodiment, includes a combustion/expansion chamber having one or more spherical surfaces located in and fluidly isolated from the first wet tank, a distribution chamber located in and fluidly isolated from the second dry tank, a plurality of heat tubes extending through the isolation member between the combustion/expansion chamber and the distribution chamber; and an exhaust tube extending from the distribution chamber and out of the inner tank system to exit the superheated steam boiler.

A boiler for producing hot water or steam, comprising a containment enclosure, which forms a heating chamber that contains water to be heated, and accommodating a firebox body, which forms internally a combustion chamber with a burner associated therewith which has a combustion head, accommodated in the combustion chamber, and a device for premixing air and gas which is connected to the combustion head. According to the invention, the premixing device comprises an air supply duct, which is connected to the combustion head, and a mixing tubular body, which is extended coaxially to the supply duct in order to create, between the internal lateral wall of the supply duct and the external surface of the sidewall of the mixing tubular body, an intake region which has a transverse air passage section that is narrower than the air passage section formed by the supply duct upstream of the mixing tubular body, along the air flow direction.

A very high efficiency internally heated steam generation system and heat exchanger are disclosed, wherein a generally rectangular housing includes end and side walls and top and bottom walls, each containing a series of small-diameter interconnected serpentine tube coil sets. A heating chamber is located at the bottom portion and at the front of the container and includes a source of fuel to generate heat within the chamber. A source of water enters the container where it is heated and passes sequentially through the several coil sets where it is heated and changes phase into steam which then passes into one or more steam tanks where it is stored and extracted when needed for a variety of uses.
