TURBINE EXHAUST ARRANGEMENT FOR IMPROVED EFFICIENCY

Номер: CA0002062444C

Steam exhaust outlets of a low pressure steam turbine are fitted with a divider plate to separate exhaust steam into isolated flow paths in fluid communication with a condenser. Separation of the flow paths is maintained through the condenser so that heat rate is improved by lower average back pressure and higher temperature condensate exiting the condenser. In a double flow turbine, a further divider plate separates steam from one exhaust outlet from that of the other exhaust outlet thereby creating four steam flow paths to the condenser.

The vaporized working medium is expanded to a lower second pressure in a steam expanding device. An energy obtained by the expansion process is discharged. The expansion of the steam state is carried out using a saturation line of the working medium. The working medium is thereby separated into a non-condensed portion and a condensed portion in a separating device. The non-condensed portion is then compressed into a compressed non-condensed portion in a compressor. The compressed non-condensed portion is cooled and condensed into a compressed condensed portion.

Автор: Song Hun CHA

A supercritical CO 2 power generating system prevents cold-end corrosion capable of improving reliability against cold-end corrosion by including a recirculation pump. Part of the working fluid heated in the low-temperature-side external heat exchanger using the recirculation pump is mixed with the low-temperature working fluid at the rear end of the pump, to heat the working fluid above the temperature of the dewpoint of the waste heat gas.

Production of mechanical/electrical energy from heat energy with and by the use of buoyancy factor on evaporation or sublimation and condensation

Номер: US20200095896A1
Автор: Sudarshan K.C.
Принадлежит: Individual

There are various source of heat energy. Amongst the various sources Solar energy, waste heat form garbage, waste heat from transformers, waste heat from chemical reactions, waste heat from plant and machinery, heat from geo-thermal or the vast heat energy lying in the seas and oceans are some of the major ones which are free and unused. Apart from these, we can also produce heat energy from fuels like fossil fuels, hydrogen gas, forest products etc. A lot of heat energy is being wasted and though converted to mechanical or electric energy it is not that efficient. However, using the evaporation or sublimation and condensation process brought about through difference in temperature and the use of buoyancy factor to increase the efficiency of the energy production, the heat energy can be converted to mechanical or electrical energy in excess of hundred percent. Moreover, heat energy obtained from hydrolysis of some chemicals like salts or hydroxides and their dehydration for reuse or the heat stored as latent heat on melting of salts can be utilized for huge storage of energy for some months or more and use it through this invention method. The energy lying in the water under the oceans during winter can be easily utilized for production of huge energy when there are very low (freezing) temperatures on the surface of the earth.
