The present invention is an apparatus and method for producing a steam and CO2 mixture, as a super heated dry steam mixture. The apparatus includes a rotatable vessel having a combustion section and a steam producing section. There may also be a dry solid removal, a steam production and solid scrubbing vertical vessel, and a heat exchanger. The vessel is partially filled with spherical bodies, and the sections are partially separated by a partition. A discharge section is located at an end of the steam producing section. A homogenizing section has at least one partition wall guiding flow of gases. The process for producing the steam mixture includes mixing a low quality fuel with an oxidation gas, combusting in a rotating drum filled with spherical bodies, and mixing low quality water with a controlled temperature to generate steam. All liquids convert to gas so that there is no liquid discharge. |

A flue system is provided for a water heater having improved heat exchange efficiency. The flue system includes an upstream heat exchange portion having at least one substantially vertical flue tube. The flue system also includes a downstream heat exchange portion having at least one substantially vertical flue tube. The upstream heat exchange portion provides a first pass for heat exchange with water in a water heater. The downstream heat exchange portion provides a second pass for heat exchange with water in the water heater. |

An annular tube heat exchanger immersed in a medium, such as a fluid. The heat exchanger comprises a fluid-tight combustion tube including a gas-fired radiant burner for providing a source of heat, at least one heat exchange tube including an inner tube disposed within an outer tube, the outer tube in thermal contact with the combustion tube, the inner tube being open-ended to allow the fluid to pass therethrough, and a fluid-tight combustion tube in thermal contact with the outer tube of the at least one heat exchange tube. The combustion gas from the radiant burner passes through the outer tube of the at least one heat exchange tube to cause an increase in the temperature of the fluid. By providing the maximum amount of heat transfer surface area, the annular tube heat exchanger provides a highly efficient means of increasing the temperature of the fluid. |

A rotary tube furnace suitable for operation in controlled atmospheres at temperatures in the range of 1500.degree. to 2800.degree. comprises a generally horizontal rotatable graphite tube slidably supported on water-cooled split ring graphite bearings. The graphite tube is rotated by means of a stainless steel drive plate and is contained within a flexible atmospheric sealing assembly and enclosure for the containment of a selected atmosphere around and within the tube and allows for the co-current or counter-current flow of gas during operation. Radiation baffles in the interior of the graphite tube inhibit radiant heat loss at the ends of the tube. The graphite tube may be constructed in two or more sections having threaded ends for ease of installation as well as removal or replacement for maintenance purposes. A heating section of the tube is heated by a plurality of graphite electrical heating elements contained within an insulated heating chamber. |

A gas powered, pressureless steam cooker has a connector tube for ingress of steam into the cooking compartment so that entry of a low temperature, wet steam can be minimized. The connector tube has a small diameter to constrain the entry of steam into the cooker compartment until it has reached a minimum velocity. A water reservoir is located alongside the oven compartment to the rear of the cooker and an integrated heat exchange tube and firebox are located in the tank. This tube is generally U-shaped, a lower horizontal leg opening at a mouth outside the water reservoir. An inshot burner fires into the lower horizontal leg and combustion gas flow through the U tube giving up heat to water in the reservoir. Additional heat exchange surface may be provided by channels through an upper leg of the U-tube from side to side. Flow of combustion gases may be optimized by the shape of the U-tube and at least a deflecting surface between a vertical web of the U and the upper leg of the U. |

A fluid heater or boiler is disclosed which has a fire tube or combustion chamber surrounded by a reservoir containing a fluid to be heated. The combustion chamber is defined by an inner shell and the reservoir is defined by an outer shell. The inner and outer shells are joined by one or more flue tubes which are thermally expandable along the axes connecting their points of attachments to the inner and outer shells. The heater is constructed so that the inner shell is deflected relative to the outer shell, when the flue tubes or inner shell expand or contract, thus accommodating the thermal expansion. The flue tubes may optionally be adapted to flex perpendicularly to their axes, as well as deflecting the inner shell, to accommodate thermal expansion. The inner shell may also be suspended within the outer shell by the flue tubes connecting the inner and outer shells. |

A multi-pipe once-through boiler having at least one row of a plurality of circumferentially arranged pipes on which a plurality of fins are arranged in such a manner that the fins are in contact with the flow of the combustion gas in a substantially parallel maner. Elements are provided for increasing the heat transfer effect, such as slits in the fins, or an inclined arrangement of the fins, or pipes without fins at the region near to the inlet of the combustion gas passageway, are provided. Furthermore, a heat insulating member for decreasing operational noise as well as a cleaner device for blow-cleaning the combustion gas passageway are provided. |
