摘要： Proposed is a ship cogeneration system using waste heat of an LNG engine ship recovered through an economizer. More particularly, proposed is a ship cogeneration system using waste heat of an LNG engine ship recovered through an economizer. The ship cogeneration system is configured to generate electric power by recovering waste heat generated from an LNG engine and providing high-temperature and high-pressure steam discharged from the economizer to an evaporator of an organic Rankine cycle. The ship cogeneration system is capable of removing soot generated on a contact surface between the exhaust gas of the LNG engine and the economizer by using some of the high-temperature and high-pressure steam.

摘要： A power generation system and related method for repowering a fossil-fueled power plant using a carbon-free nuclear steam supply system (NSSS) which replaces the existing fossil plant steam generator which burns fossil fuel such as coal, oil, or natural gas. The existing fossil plant energy conversion system including the turbine-generator (turbogenerator) and auxiliary components of the Rankine cycle is retained. The NSSS may include a small modular reactor (SMR) unit comprising a reactor vessel with nuclear fuel core and steam generator which receives heated primary coolant from the reactor to produce main steam to operate the Rankine cycle. The main steam output by the SMR unit is compressed in a steam compressor to increase its pressure to a level necessary to operate the turbogenerator. The compressor may be operated via a portion of the main steam. An intercooler of the compressor may be used for main steam reheating.

摘要： A system includes a retention system configured to support a heat exchanger along a flow path within a duct. The retention system includes a first sleeve configured to extend between opposite first and second walls of the duct, a first cable extending through the first sleeve, and a first bumper coupled to the first sleeve. The first bumper is configured to contact the heat exchanger. The retention system includes a first tensioner coupled to the first cable, wherein the first tensioner is configured to provide a first tension in the first cable. The first tension is adjustable to detune the natural frequency of the heat exchanger away from any excitation load frequencies caused by an exhaust gas flow through the duct.

摘要： A method and system in which a waste gas or liquid product is combusted or otherwise used at a well site or other source location to drive a generator to produce electrical energy which is then stored in a portable storage device, such as rechargeable battery or an array of rechargeable batteries, which can subsequently be transported, for example, to a charging station for vehicles or other electrical devices or systems, or to a delivery location for downloading the portable stored electrical energy to a power supply grid.

摘要： An energy storage system (TES) converts variable renewable electricity (VRE) to continuous heat at over 1000° C. Intermittent electrical energy heats a solid medium. Heat from the solid medium is delivered continuously on demand. Heat delivery via flowing gas establishes a thermocline which maintains high outlet temperature throughout discharge. The delivered heat which may be used for processes including power generation and cogeneration. In one application, the energy storage system provides higher-temperature heat to a steam cracking furnace system for converting a hydrocarbon feedstock into cracked gas, thereby increasing the efficiency of the temperature control.

摘要： The invention is concerned with a method for combined production of nanomaterials and heat. The method comprises feeding at least one precursor material and a fuel into a combustion unit for the generation of heat and nanoparticles, whereby the precursor material is combusted to be decomposed and oxidized in a sufficient temperature. The heat generated in the combustion of the fuel and the precursor material is recovered by using at least one heat exchanger. The combusted fuel is cooled down and the nanoparticles generated in the form of oxides in the combustion are collected. The system of the invention for combined production of nanomaterials and heat comprises a combustion unit, means for feeding at least one precursor material, fuel and oxidizer into the combustion unit for combustion, a heat exchanger for recovering heat from the combustion unit, and for cooling the combusted fuel, and means for collecting nanomaterials in the form of oxides from the combustion of the precursor material(s).

摘要： The disclosed concept relates to a novel modified and simplified Rankine steam-turbine cycle without rejection of heat in the cycle, which is driven by a thermocompressor (ejector) operating in the wet-vapor region, to the end of achieving of the maximum possible (˜100%) thermal efficiency of the thus modified Rankine cycle. Wet-vapor mixture circulating within the thermocompressor is being separated in a cylindrical separation tank, so that the saturated water is pumped to a water heater where it receives the cycle heat input, while the saturated vapor is expanded in a backpressure steam turbine producing useful mechanical work and is then recirculated back to the thermocompressor, where it is being re-pressurized by the primary fluid (pumped and heated saturated water). The concept can be applied to steam-turbine-cycle power-plants fueled by: coal or solid/liquid/waste fuel, nuclear fuel (using boiling water reactors, pressurized water reactors, pressurized heavy-water reactors, gas-cooled reactors, molten salt reactors or liquid-metal-cooled fast reactors) or renewable energy sources (Solar energy, biomass, geothermal), The concept can also be used in the form of the bottoming steam-turbine-cycle part of a combined gas-turbine/steam-turbine cycle power plant.
