Steady state turbine power optimization was conducted by analyzing the relationship between the expansion turbine and four actuators: working fluid pump speed, mass flow distribution between the parallel evaporators, turbine speed, and coolant pump speed [15].
Then, an expansion turbine is used to rapidly expand the chilled gases, which causes the temperature to drop significantly.
This approach, commonly known as a bootstrap configuration, utilizes high pressure, high temperature air taken from the engine that is first cooled, then compressed, then cooled again before delivery to an expansion turbine through which cold air is generated.
Similarly, the performance of expansion turbine (expander) parameters was monitored and the results indicate a considerable decrease in turbine efficiencies as the inlet gas pressure increases resulting in an increased power output of the turbine leading to a higher liquefaction rate.
* Some chillers are large enough such that the small increase in COP justifies the addition of a specially designed expansion turbine. These exceptions aside, the majority of cooling systems use a constant enthalpy, throttled expansion.
The air drives a small expansion turbine to generate electric power.
The expansion turbine extracts the heat from the compressed air stream, so the exhaust air is usually cooler than ambient room temperature.
Tenders are invited for procurement of spares for expansion turbine - cryostar
The order covers an expansion turbine for a 5.5 MW geothermal power plant under construction in Mauerstetten, in southern Germany.
Main components include the expansion turbine and a generator unit with 140 kW.
Tenders are invited for Expert supervisory services for overhauling or troubleshooting of cryostar make expansion turbines at panipat refinery.
These unique direct-expansion, positive displacement devices are unaffected by variations in pressures and flows and solve the challenges of expansion turbines. They are capable of directly utilizing the pressure in natural gas, wet steam, dry steam, geothermal fluids and many other waste streams and waste heat.
