Steam gets scary in many ways at very high temperatures, and a Rankine cycle isn't all that efficient (although can be (and generally is) improved with "reheat" cycles ... which are needed in the ...

Thermodynamic Evaluation If we assume the adiabatic efficiency of the Rankine cycle ethane turbine is 85%, the conditions listed in Table 1 determine a 20% cycle efficiency at the shaft. Heat rejected ...

Much of the world’s electricity comes from turbines powered by steam created by the heat from nuclear reactors, solar collectors, and burning fossil fuels. Most of those turbines and power plants use ...

When I began my power industry career years ago (initially in the chemistry lab of a coal-fired power plant), the criticality of proper chemistry control of steam boilers, cooling water systems, and ...

One of the world’s largest biomass-fed organic rankine cycle (ORC) plants is getting ready to begin operations. Italian firm Turboden is preparing to put online an 8-MW power unit in Athens, Maine, ...

Fuel-agnostic and suitable for newbuilds and retrofit, Organic Rankine Cycle waste heat recovery systems are making headway ...

Researchers are moving into the demonstration phase of a novel gas turbine system for power generation, with the promise that thermal-to-electric conversion efficiency will be increased to as much as ...

Researchers at Sandia National Laboratory have developed a gas turbine for generating electricty from steam that relies on the Brayton cycle. It promises 40% more power in a smaller, more compact ...
