Abstract: A method for producing steam includes combusting a fuel and an oxidant to generate heat in a combustion stream, and injecting impure water into the combustion stream such that the heat produces a steam stream including particulate matter precipitated from the impure water.

Abstract: A method for purifying water involves heating impure water in a first reboiler, a second reboiler and a combustion steam generator to ultimately produce about 3 parts by weight of clean water and about 1 part by weight of clean steam for every 4 parts by weight of the impure water. A water treatment system includes a gas-fired combustion steam generator that is operable to produce a hot steam stream. A reboiler is connected in receiving communication with the gas-fired combustion steam generator to receive the hot steam stream. A separator is connected with the reboiler and is operable to separate an output stream from the reboiler.

Abstract: A method for use in manufacturing a ceramic matrix composite article includes assembling a ceramic fiber sheet between a tool and a die, where the tool is conformable to the shape of the die and the melting point of the die is greater than the melting point of the tool. The assembly is then heated to soften the tool. At least one of the tool, the die or a separate inflatable member is then pressurized to conform the tool and the ceramic fiber sheet to the die. Next, the assembly is cooled and the pressure is vented before removal of the tool and ceramic fiber sheet from the die. A preceramic resin with a catalyst is then applied to the ceramic fiber sheet and cured at a curing temperature that is below the melting point of the tool, to form a preform. The tool is then removed from the preform.

Abstract: A bellows includes a flexible section including a series of convolutions extending between a first end and a second end. The convolutions are formed of a nano-grained aluminum alloy.

Abstract: A heat transfer tube includes a container, a cavity within the container, and a heat transfer medium located within the cavity. The heat transfer medium consists essentially of a solid-gas suspension of a gas and a substantially homogeneous nanoparticle powder located within the cavity. The cavity is in a partial vacuum state. The nanoparticle powder comprises Ca(OH)2, LiH, ZrH2, or Mg(OH)2 in a solid state and is capable of substantially freely emitted and reabsorbing the gas as a function of temperature.

Abstract: An apparatus that promotes the flow of materials has a body having an inner shape for holding the materials, a wall having a shape that approximates a portion of the inner shape of the body, and a vibrator attached to the wall. The wall may be disposed vertically within the body close to the body's inner shape. The vibrator transfers vibrations to the wall to agitate the material and encourage material flow.

Abstract: A valve system intermediate a secondary flow path and a primary flow path to selectively communicate secondary airflow into the primary gas flow path and control airflow injected from a higher pressure plenum into a lower pressure flowpath.

Abstract: A flow battery stack includes a plurality of flow battery cells, a manifold and a heat exchanger. Each flow battery cell includes an electrode layer that is wet by an electrolyte solution having a reversible redox couple reactant. The manifold includes a solution passage that exchanges the electrolyte solution with the flow battery cells. The heat exchanger includes a heat exchange fluid passage.
