Heat Recovery Solutions
Since the mid 2000s, HRS has been designing and building ORC based systems to convert wasted heat into usable electric power. We used advanced magnetic bearings, high speed power electronics and compact self-cooling permanent magnet generators to bring cost effective solutions to the small industrial market. The Clean Cycle I (CCI) with 125 kW gross power rating was installed over 100 times and produced > 1,000,000 MWh. Many continue to run today.
Then we developed the Clean Cycle II (CCII) with 140 kW gross power rating. Still based on the core technologies, but with increased standardization and optimized packaging. This reduced application specific design work and minimized installation requirements. Allowing access to medium temperature sources of steam, flue gas, cooling thermal oils and pressurized hot water systems.
Today we continue to develop the CCII and install heat recovery solutions around the world with operating units in the Americas, Europe, and Asia. We have also partnered with a great company to bring productive heat recovery to larger situations, allowing us to provide cost competitive solutions for applications with heat flows from 750 – 10,000 kWth.
Numerous Successful Applications
The Clean Cycle generator has been successfully applied to many waste heat applications and is ready for many more. Any application where the heat can be captured to a thermal oil, steam, or pressurized hot water, and in some cases directly to the working fluid, are applications waiting to be explored.
The Clean Cycle containerized solution has been meticulously engineered to be reliable and efficient on a variety of different heat sources. All major components have been assembled into a single package to create an automated machine that generates electricity from nothing other than a hot water or steam loop.
Gas engines
Waste heat in the exhaust and sometimes in the jacket cooling can be turned into valuable additional electrical output. Biogas engines, which often qualify for lucrative feed-in-tariffs, have been demonstrated with the Clean Cycle(tm) solutions from landfill gas engines to waste water treatment plants.
Diesel Generators
A Clean Cycle(tm) generator paired with single or multiple liquid fuel engines to increase the overall fuel efficiency of generator installation. On a typical diesel Engine, one Clean Cycle generator will offset 150,000 liters (~40,000 gal) of fuel per year. Regardless of the fuel type - including diesel, fuel oils, LNG, etc. - the engine produces heat that the Clean Cycle can convert into electricity.
Biomass boilers
Boilers, specifically those designed to burn waste biomass, have been used for many years to reduce waste storage, transport, and tipping fees while producing sellable electricity. Industrial or agricultural by-products, such as shell husks, sawmill clippings, refuse, and even forms of biogas have been converted to a hot transport medium and then converted to valuable electricity in the Clean Cycle Units.
Compression/Pump Stations
Compression or pump stations used throughout the world to transmit gas and oil through pipelines produce heat and vent this through a standard exhaust stack. Both turbine compressors and reciprocating compressors are suitable candidates for heat capture and conversion to usable electricity for direct on-site use or resell to the grid.
Gas Turbines
Gas Turbines that generate electricity or pump/compress also create a substantial amount of heat that is vented in their exhaust. Small scale microturbines can power a Clean Cycle solution. Larger turbines can power other products to generate substantial amounts of additional electricity.
Industrial Processes
Many industrial facilities have vented or wasted heat that could be captured and converted to electricity to reduce grid power consumption or to sell back to the grid. If it is pressurized hot water, gas flue, or thermal oil loop, there is a possibility to do something productive with your heat. Sometimes, we can convert your power consuming cooling system into a power producing cooling system.
