An advanced molten salt once-through steam generator system functional on hot molten salt supplied via a supply line. The system includes a steam generator, a feedwater supply line, at least one high pressure heaters and a separator. The molten salt is supplied the steam generator, which includes at least one economizer, an evaporator, and a superheater to utilize the heat of the molten salt flowing from the superheater to economizer to generate steam. The feedwater line supplies the feedwater to the steam generator, flowing from the economizer to the superheater to be converted into steam by the hot molten salt. The heaters are arranged in series in the feedwater line to heat the feedwater up to required temperature. The separator enables separation of the water and steam.

Systems and methods are disclosed that may include producing wellhead gas from a wellbore, removing hydrocarbons and/or other particulates from the wellhead gas produced from the wellbore to maximize and/or provide a consistent BTU level to the wellhead gas, and burning the wellhead gas in a wellhead gas burner to heat water and/or other chemicals used in hydrocarbon production and/or well completion processes, including, but not limited to hydraulic fracturing (fracking). The wellhead gas burner may also be configured as a primary heat source and integrated with a traditional gas burner system configured as a supplemental heat source. The wellhead gas burner and the traditional gas burner may also be operated simultaneously. The wellhead gas burner may also be mounted to a mobile superheater truck.

A heat exchanger including a pipe bundle to guide a fluid between first and second pipe connectors, the pipes being distributed in layers of pipes, wherein pipes of each of the layers of pipes each includes. A length of a flow path section is at least 1.7 times greater than lengths of two other flow path sections, wherein a first bend of the two bends is provided between the longer flow path section and a first of the shorter flow path section, and wherein a second of the two said bends is provided between the first, shorter flow path section and the other shorter flow path section, and wherein each of the layers of pipes includes two pipe subgroups. The bend between the two shorter flow path sections of the respective pipes in one of the pipe subgroups in the pipe layer is arranged substantially opposite to bends extending between the two shorter flow path sections of pipes in the other pipe subgroup of the same pipe layer.

Energy storage systems are disclosed. The systems may store energy as heat in a high temperature liquid, and the heat may be converted to electricity by absorbing radiation emitted from the high temperature liquid via one or more photovoltaic devices when the high temperature liquid is transported through an array of conduits. Some aspects described herein relate to reducing deposition of sublimated material from the conduits onto the photovoltaic devices.

In a clean boiler with steam conversion and hydrogen/oxygen pre-blending, the clean boiler comprises two identical boiler bodies integrated to form a single entity. The clean boiler comprises two slim cavities, four water-containing chambers and four combustors, which is heated at wide faces and generates steams rapidly. The boiler comprises an integrate body containing two independent boiler bodies (1), and each of the independent boiler bodies (1) contains an independent boiler chamber (19). A steam conversion and transformation system is simultaneously provided for introducing a part of steam into the independent boiler chamber (19). High temperature of the boiler chamber (19) is utilized to promote a decomposition of the steam into H.sub.2 and O.sub.2. Water formed by H.sub.2 and O.sub.2 is utilized as a fuel to provide a self-sustaining combustion and heating, thus reducing a dependence on a primary energy source, reducing carbon emissions and protecting the environment.

The present invention provides an infrared hydrogen/oxygen combustor. The structure of the combustor includes a sinus ring (1). A surrounding foot (12) of the angle-shaped sinus ring (1) wraps a material-containing basin (14). A first small tube (16) and a second small tube (7) are connected the material-containing basin (14) and the angle-shaped sinus ring (1). Water solution (3) is contained in the material-containing basin (14). A straight-hole ceramic water-absorbing board (5) is provided on the upper part of the water solution (3), a spacing ring (6) is provided above the side of the material-containing basin (14) and in the upward ring of the angle-shaped sinus ring (1), a two-stage material-containing box (9) with a separated brake is provide on one side of the angle-shaped sinus ring (1). The technical scheme of the invention reduces the production cost, the pollution and protects the environment.

A solar automatic heat collecting and equalizing tube, including: a glass tube, an absorption tube, and a baffle. The glass tube is sleeved on the absorption tube. The absorption tube is coated with a heat absorption layer. The space between the glass tube and the absorption tube is vacuum. The baffle is disposed in the inner cavity of the absorption tube and is configured to drive a fluid in the absorption tube to tumble up and down alternately. The baffle is spiral in shape and fixed in the absorption tube.

In an externally integrated once-through steam generator type small modular reactor, a steam generator is arranged along the circumference of a reactor vessel, and secondary cooling water flows in heat transfer tubes and changes to superheated steam.
