Sistema de recuperación de calor descentralizado


Oferta Tecnológica
Una empresa alemana ha desarrollado un sistema de recuperación de calor residual (WHR) basado en ciclo Clausius-Rankine (CRC) y ciclo orgánico de Rankine (ORC) en 1-5 kW (AC). Las áreas de aplicación incluyen aplicaciones estacionarias, aplicaciones móviles, microturbinas de gas, procesos industriales, combustión de biomasa y generación de energía solar térmica y geotérmica. Actualmente la empresa está implementando la tecnología en la fase 1 del Instrumento Pyme del programa H2020. Se buscan universidades, industrias y pymes para implementar la tecnología en la fase 2 o formar un consorcio para la próxima convocatoria de energía o Eurostars (Eureka). La empresa ofrece acuerdos de cooperación en materia de investigación.


Decentralized heat recovery
A company from the Northeast of Germany has developed a waste heat recovery (WHR)-system based on Clausius Rankine Cycle (CRC) and Organic Rankine Cycle (ORC) technology in the 1-5 kW (AC). Currently the SME is implementing the SME-instrument Phase 1. The company seeks for partners (universities, industry, SME) in order to jointly implement SME-instrument Phase 2 or to apply in a consortium for further Horizon 2020 energy call or Eurostars (Eureka). Research cooperation agreement is offered.
The young technology company has developed an innovative small scale WHR-system in a power range up to 50 kW electric. The USP is in a special expansion machine based on a rotary piston engine. The technology is registered in several patents worldwide. The first patents have been issued.

With support of private investors and public funding the technology could rapidly be enhanced on industrial maturaty. The next step is to entry the European and later the global market.

In 2013, the single disc version was operated for more than 100 hours. In beginning 2014, the latest generation of the expander was put into operation as a 2-disc-version allowing for performances of more than 11 kW to be reached. Further developments will focus on a long service life, low friction and a high expansion efficiency ratio. Special focus will be put on the following mechanical engineering's challenges:
· Wear and tribology
· Efficiency
· Robustness

Application areas are:
o Stationary Applications: CHPs and Gen-Sets in the field of energy and heat production, e.g. CHPs in the bio- or landfill gas sector as well as for all decentralized energy supply options (gas and diesel generator units).

o Mobile Applications: combustion engines are to be found in the automotive sector, within commercial and building-site vehicles, the maritime and train sector.

o Micro Gas Turbine: Micro combined cycle power plants integrate both - the heat source (micro-gas turbine) and the WHR-System. Micro Gas and Steam Power plants would create a complete new product segment.

· Industrial processes: Industrial waste heat refers to energy that is generated in industrial processes without being put to practical use. Sources of waste heat include hot combustion gases discharged to the atmosphere, heated products exiting industrial processes, and heat transfer from hot equipment surfaces.

· Biomass combustion: ¿lectricity and/or heat production from the combustion of biomass is an important alternative to conventional techniques of biomass combustion, with distinctive economic and environmental advantages, especially in smaller installed capacities

· Solar thermal and geothermal power generation: Small solar power stations and geothermal power stations can ensure a decentralized energy supply in sun-belt-/geothermic countries worldwide.

The company is currently implementing the Horizon 2020 SME-instrument, phase 1. The application for Phase 2 will be in March 2015. Partners (universities, industries, SMEs) to jointly enhance the technology or help to entry the global market are welcome.

The company is further looking for partners (universities, industries, SMEs) to jointly implement research and innovation activities in the frame of Horizont 2020 calls (SME-instruments-Phase 2 and Workprogramme 10, Secure, clean and efficient energy) or Eurostars (Eureka). Thus, a research cooperation agreement is offered.
Advantages and Innovations:
The USP of the developed WHR-system is the rotary piston expander. Its key features are low costs, simplicity and wet steam tolerance. This allows the simplest possible and therefore most efficient CRC-system set-up which competitors so far cannot match. The end user will enjoy an early return on investment (in about three years) and reduced energy costs (about 15%).

Another great advantage of the new technology is the flexibility in terms of the heat source. In principle WHR-Systems can be adapted to different kinds of heat sources. Above-average market potential for the environmentally friendly and CO2 neutral electricity and heat production is identified for waste heat delivered from exhaust gas of combustion engines and turbines. Further applications for small scale WHR-Systems are seen in the power generation through biomass combustion as well as in the geothermal and solar thermal energy generation. Within the feasibility study we will analyse the market for energy efficiency and energy production technologies based on CRC / ORC- technologies.
Stage of Development:
Proposal under development
Patent(s) applied for but not yet granted,Patents granted
CommeR Statunts Regarding IPR Status:
The company has a wide patent portfolio for the rotary expansion engine. The patent portfolio (granted and pending) is not solemnly targeting the expander based on the rotary piston engine alone. Their focus is waste heat utilisation by using expander- and "equally suited technology". This ensures needed flexibility for further developments and marketing activities.
