With global requirements for renewable energy becoming increasingly significant, it is imperative Australian industry keeps pace with developments in energy generating technologies.
Responding to the demands for clean, renewable energy, Kaishan Australia now offer a range of custom designed and innovative Screw Expander Power Plants.
Proven in multiple power co-generation applications throughout the world, these plants are designed and built by the global Kaishan Group to utilise a broad range of available waste energy sources including high pressure gas, steam and waste heat – converting otherwise wasted energy into usable electricity, channeled directly back into production or returned to the grid for a significant energy cost reduction to the source company.
These advanced expander systems have ideal applications in geothermal, diesel engine heat discharge, gas pipelines, furnace applications and waste steam. Installing an expander will typically see a very quick return on investment (subject to current energy costs and conditions), making them a workable and worthwhile asset for any business looking to save energy.
ORC POWER EXPANDER
ORC POWER EXPANDER
Kaishan is a leading manufacturer of Organic Rankine Cycle (ORC) power generation systems. Our products represent annual new generation of well over 1000 MW of power in facilities around the world, where they play a key role in curbing CO2 emissions and reducing overall environmental impact.
Kaishan’s ORC power plants feature a patented screw expander system capable of achieving isentropic efficiency by as much as 90% compared to conventional turbines. Our ORC expanders are versatile and easy to fit into your existing workflow, with multiple condenser options and power generation capabilities ranging from 50kW to multi-megawatts.
Our ORC expanders can be configured to produce energy from any of the following sources:
Water used for diesel or gas engine cooling circuits.
Geothermal hot water (brine).
Ethanol, gasoline, thermal oil and other chemicals.
Exhaust gases produced by conventional turbines or gas or diesel IC engines.
Hot gases from kilns and furnaces used in cement, glass and other manufacturing.
Any application where heat can be transferred to a fluid.
Since the 19th century, power plants have used steam turbines to generate clean energy. However, the technology has its limitations — the process is inherently inefficient and the presence of moisture in the system leads to premature wear and corrosion.
Kaishan steam screw expanders are positive displacement machines that allow power plants to run at slower speeds without the performance or safety issues of a conventional turbine. As a result, they broaden the possibilities for industrial power recovery and power generation.
With a steam screw expander, power plants can accept saturated, dry or overheated steam — and, when combined with an organic Rankine cycle (ORC) system, many types of gas as well. Steam screw expanders also help with decompression, cooling and other functions.
A Kaishan screw expander generator can provide:
Pressure regulation in steam or gas pipelines.
Power generation from flash steam and geothermal brine.
Heat recovery and waste pressure recovery at low temperatures and low pressures.
Kaishan Compressor steam screw expanders are versatile pieces of equipment that work with co-generation, waste heat recovery and waste pressure recovery equipment. They are easy to install and maintain even in demanding operations.
