摘要:
A thermodynamic cycle composing of two sub-cycles, an evaporation cycle, in which we should select a fluid (A) with a low latent heat (for example Rll) and a condensation cycle, in which we should select a fluid (B) with a very high latent heat, and low density (for example water). This cycle can be used to generate mechanical energy and can be used with a distillation unit to distill water. The fluid (A) in the evaporation cycle is evaporated, so it expand and move through a pipe to a height H, then it condensed by the other fluid (B) in the condensation cycle, that is also pumped to the height H, the Fluid A is then filling a pipe with height H. At the bottom of the pipe a hydrostatic turbine (115) generates a mechanical energy that is proportional to the height H. The energy gained from the turbine can be maximized by using a multistage cycles where using the heat energy that fluid (B) gains from condensating the fluid (A) in one stage to evaporate the fluid (A) in another stage. The evaporation stage may contain a steam turbine between evaporator (111) and condensor (113).

摘要:
A steam turbine system is described comprising at least one high pressure turbine, and / or at least one intermediate pressure turbine, and at least one first low pressure turbine, mounted on a first rotary shaft that is coupled to drive at least one first electrical generator; and at least one further low pressure turbine, mounted on a further rotary shaft that is coupled to drive at least one further electrical generator. The same rotary generator on the further shaft may be connected by flexible couplings to at least two or more low pressure turbines for multiple units within the same power plant. There is a steam supply system to supply low pressure steam to the low pressure turbines provided with a steam outlet to enable extraction of auxiliary process steam from a location in the steam supply system upstream of the further low pressure turbine but not upstream of the first low pressure turbine. The system is described as part of a steam generator fuelled by carbonaceous fuel combustion with post combustion carbon capture capability.
摘要:
A specific electrical generator powered by an external combustion steam engine that functions through the initial combustion of various potential fuel sources to consequently generate steam from an internal working fluid that drives an electric motor or alternator to generate electricity is provided. The steam is then condensed to return to its liquid form in order to again be heated into steam through further combustion. The all-in-one electric generator combusts the fuel provided within the generator and incinerates such fuel in a manner and in an environment to effectively eliminate the potential for appreciable resultant levels of nitrogen and/or sulfur oxides. The combustion fuel may be any type of material, such as used vehicle or equipment oil, waste vegetable or cooking oil, diesel, gasoline, syngases, natural gases, and the like.
摘要:
A fossil fuel fired power plant for the generation of electrical energy comprises a water steam cycle and a plant (10) for the capture of CO2 from exhaust gases emitted by the power plant and a steam jet ejector (24) configured and arranged to receive an input steam flow from a low- or intermediate pressure extraction point in the power plant and to increase its pressure. It is further arranged to receive motive steam (25) from a further extraction point in the power plant. A steam line (27, 22) directs the steam of increased pressure from the steam jet ejector (24) to the CO2 capture plant (10). The power plant according to this invention allows the use of low-pressure steam for the operation of the CO2 capture plant, where the extraction of such steam affects the overall efficiency of the power plant to a lesser degree than in power plant of the state of the art.
