Solar/Rankine steam cycle hybrid concentrating solar power (CSP) systems and methods for designing or retrofitting existent natural circulation boilers using saturated or superheated steam produced by direct steam generation (DSG) or Heat Transfer Fluid (HTF) steam generators and CSP solar field technology systems are described. Additionally, methods and processes of retrofitting the existent Heat Recovery Steam Generators (HRSG) or biomass, gas, oil or coal fired boilers to operate integrated to a molten salt/water-steam heat exchangers are disclosed. The hybrid CSP systems are highly efficient due to the increase of steam generated by the solar section comprising either the DSG receiver or the molten salt-water-steam sequential heat exchangers, pre-heaters, boiler/saturated steam generators, super-heaters and re-heaters. The additional saturated, superheated and reheated steam produced is directed to a Rankine cycle according to its pressure, temperature and steam quality significantly reducing the fuel consumption within a cogeneration or Combine Cycle Power Plant.

The method is for conveying solar power from a sun. A solar concentrator conveys and concentrates solar power as rays into a glass rod. The solar concentrator has a tapering device disposed at a bottom thereof. The glass rod has a first curved glass loop section, a second curved glass loop section and a straight glass section. The straight glass section has an outer end that is positioned in proximity to a water surface to heat the water. The first loop section is rotated relative to the second loop section at a first gap and the second section is rotated relative to the curved section at a second gap so that the concentrator can follow the path of the sun during the day.

(A) The inventions field is innovations in renewable energy production and desalinization. (B) The technical problems the invention addresses are: i. Solar systems require cells to harvest energy. Large-scale solar farms often pose significant environmental hazard, and require real estate to harbor them. ii. Evaporative desalinization plants require significant amounts of energy to produce clean product.

(C) The invention solves both problems by utilizing the solar heat absorbed into surface water. It needs no solar cell, and the real estate needed to found a productive plant is minimal. Instead of distillation it uses crystalline cold purification, which produces energy with its co-process instead of requiring energy input. Co-processes can be utilized to remove organic compounds from the by-product.

(D) The principal use of the invention is to combat anthropopogenic climate change by removing heat from the global system. Further if carbonic compounds are removed oceanic acidification may be reduced.

The present invention discloses a pump-type autoclave system and a providing method for steam and pressure thereof, wherein the pump-type autoclave system comprises an autoclave, a steam providing device and a compressor, said steam providing device comprises a water storage container and a heating device used for heating said water storage container, said water storage container, the compressor and the autoclave are connected through a pipeline to form a closed loop, an inlet of the compressor is connected with a steam output port of the water storage container, an outlet of the compressor is connected to a steam input port of the autoclave, and a condensate water drain outlet of the autoclave is connected to the water storage container. The present invention uses the compressor to depressurize an intermediate-low temperature water source to obtain steam, and the steam is pumped into the autoclave and condensed to release heat to obtain corresponding temperature and pressure. Since the present invention fully utilizes a great amount of low-cost intermediate-low temperature heat sources obtained from natural, industrial or living waste heat to provide needed high temperature, steam and pressure to the autoclave system, the energy is saved.

A solar-powered generator captures solar energy and generates steam with the energy. The generator includes a container formed with an inner spherical wall defining an inner chamber and having an inner reflective surface containing photovoltaic cells and an outer spherical wall defining an outer chamber located between the inner and outer spherical walls. The container is formed to allow for sunlight to enter the inner chamber. An inlet port is configured to allow water to enter the outer chamber and an outlet port is configured to allow steam to exit the outer chamber, whereby sunlight entering the inner chamber through the passage bounces off of the inner reflective surface allowing thermal energy to heat the water in the outer chamber to create steam to generate electricity through an external steam turbine. While simultaneously using radiant energy to be absorbed by photovoltaic cells to generate additional electricity.

An apparatus for raising the temperature of superheated steam includes an inlet into which superheated steam is introduced, a body to raise the temperature of the superheated steam heated by an external heat source and introduced through the inlet, and an outlet provided inside the body and discharging the superheated steam temperature-raised by the body to the outside, in which an inner surface of a sidewall of the body is formed with an inner protrusion for heating the superheated steam while spirally rotating the superheated steam. The Apparatus enhances the flow of superheated steam in the process of raising the temperature by further heating superheated steam caused by waste heat generated in a waste combustion apparatus or the like, and at the same time, increases the area of contact of the superheated steam with a heat source to improve the temperature-raising efficiency.
