A piping system of a steam turbine plant is provided with: steam piping connected to a steam turbine; bypass piping which branches from the steam piping at a branching portion and which is connected to a condenser; a steam check valve provided between the branching portion of the steam piping and the steam turbine; and a turbine bypass valve provided in the bypass piping. A piping system cleaning method includes the steps of: connecting at least one valve of the steam check valve and the turbine bypass valve and a connecting portion provided between the turbine bypass valve of the bypass piping and the condenser, by using temporary piping having a foreign matter collecting portion; closing a flow path on the outlet side of the valve; cleaning the steam piping by supplying steam to the steam piping; and sending the steam to the condenser through the temporary piping.

A dry-cooling system useful in absorbing heat from a heat source and related dry cooling methods including a depolymerization cooling unit (DCU) in fluid communication with a polymerization heating unit (PHU). The DCU includes a DCU heat exchanger which receives a polymer and a catalyst, wherein contact of the polymer and the catalyst within the DCU heat exchanger causes an endothermic reaction, converting the polymer to a monomer and drawing heat from a first heat source. The monomer is then withdrawn from the DCU. The PHU includes a PHU heat exchanger, which receives the monomer, wherein contact of the monomer with the catalyst causes an exothermic reaction within the PHU heat exchanger, converting the monomer to the polymer. The polymer is then withdrawn from the PHU for conveyance back to the DCU, and the cycle is repeated.

A nuclear power plant with a steam dump device and condenser for the nuclear power plant.

Improved steamblow commissioning of a steam plant with continuous filtration of particle laden condensate through dual strainer filters with backflush means operatable in parallel to enable isolation of one and backflushing while the other is backflushed and venting backflushed particles to waste to enable an uninterrupted commissioning process recycling steam with significant particulate burden relived by continuous cycling in alteration through the dual filers and removal of particles to waste with backflush.

The heat cycle facility includes: a first vaporizer that vaporizes a first liquid heating medium by combusting fuel; a first motive power generator that generates motive power by using as a drive fluid a first gas heating medium obtained at the first vaporizer; a condenser that condenses the first gas heating medium discharged from the first motive power generator by heat-exchanging the first gas heating medium for a second liquid heating medium; a circulator that pressurizes the first liquid heating medium obtained at the condenser and supplies the pressurized first liquid heating medium to the first vaporizer; a second vaporizer that produces gaseous ammonia by heat-exchanging the second liquid heating medium for liquid ammonia; and a supplier that supplies the liquid ammonia to the second vaporizer.

A system for processing wastewater includes a wastewater source, a biomass burner, and a first heat exchanger. The biomass burner is configured to receive biomass from a biomass source, combust the biomass to produce heat and ash, receive a thermal transfer fluid, and heat the thermal transfer fluid using the heat produced from the combustion of the biomass. The first heat exchanger is configured to heat the wastewater to produce steam. The first heat exchanger includes a first inlet, a second inlet, a first outlet, a second outlet, and a third outlet. The first inlet is configured to receive the wastewater from the wastewater source. The second inlet is configured to receive the thermal transfer fluid from the biomass burner. The first outlet is configured to discharge the steam. The second outlet is configured to discharge the thermal transfer fluid.

The disclosed apparatus and control system produces a single, on demand, energetic gaseous working fluid from any heat source. Working fluid in a liquid phase is released into a heat exchange tube in the form of very fine droplets or atomized mist, where it is rapidly heated to its gaseous phase. The gaseous working fluid can continue to absorb heat before exiting the heat exchange tube to perform work. The disclosed system controls the release of working fluid into the heat exchange tube and/or the heat energy to which the tube is exposed, resulting in a flow of energetic gaseous working fluid that can be quickly adjusted in response to changing conditions without a large pressure vessel.

A process for energy storage comprises carrying out a cyclic thermodynamic transformation wherein, in a charge phase, a condensation of a working fluid is executed by means of heat absorption by a heat carrier in order to store the working fluid in the liquid or supercritical phase; in a discharge phase, an evaporation of the working fluid is executed starting from the liquid or supercritical phase and by transfer of heat from the heat carrier; provision is made for actively adjusting at least one parameter of the working fluid related to the condensation and/or to the evaporation, in order to control at least one temperature of the heat carrier and uncouple it from the ambient temperature without the aid of systems outside the cyclic thermodynamic transformation.
