Patch is a 25+ year veteran of the energy field  Waste heat recovery, fossil fuels, biomass, fuel cells, lithium-ion batteries, and nuclear instrumentation  Residential-, commercial-, industrial-, and utility-scale Introduction Typical CFD Turbine Analysis Results
  4. 4. 4© 2014 Concepts ETI, Inc. All rights reserved. We need to plan our effort to develop required ORC codes, standards, and regulations Why?  Today, every country has their own codes, standards, and regulations that apply to ORC components and systems  It makes sense to unify these disparate regulations A few generally applicable international standards exist  ISO, IEC, International Fire Code, etc. A few related international standards exist  ISO 27.040: gas and steam turbines; steam engines No international standards exist for ORC components or systems Problem Statement
  5. 5. 5© 2014 Concepts ETI, Inc. All rights reserved.  Initially focus on standards/regulations for ORC system components  Valves, pumps, heat exchangers, expanders, etc.  Next focus on equipment standards/regulations for ORC subsystems  Subsystem = expander + heat exchangers + pump + piping • Might not include heat source and cooling source supplies  Two types of standards/regulations • Equipment • Performance determination  Next focus on equipment standards/regulations for complete, installed ORC systems  System = expander + heat exchanger + pump + piping + heat source + cooling source  Two types of standards/regulations • Equipment • Performance determination Potential ORC Workgroup Direction
  6. 6. 6© 2014 Concepts ETI, Inc. All rights reserved. Draft complete list of necessary codes and standards  Components, subsystems, and complete systems Investigate adopting generally applicable international standards  Electrical, mechanical, fire safety, safety, etc. Investigate modifying related international standards  Modify ISO 27.040 steam turbine and steam engine standards to meet ORC requirements? Investigate modifying related national standards  If no international standard is available  If the national standard is more applicable to ORC systems Write new ORC standards  Borrowing from existing standards, as appropriate Suggested Outline of Work
  7. 7. 7© 2014 Concepts ETI, Inc. All rights reserved. Perhaps select a basis similar to ISO gas turbine standards  Single operating point – with corrections? Perhaps select a specific number of operating points?  Various heat source temperatures?  Various heat sink temperatures? Perhaps compare performance as a percentage of Carnot efficiency? Comments? ORC Subsystem and System Performance Thoughts
  8. 8. 8© 2014 Concepts ETI, Inc. All rights reserved. CSA B52-05 – Mechanical Refrigeration Code  Piping, pressure relief valve locations, etc. ANSI/UL (IEC) 60335-2-34, Standard for Household and Similar Electrical Appliances, Part 2: Particular Requirements for Motor-Compressors  Including hermetic refrigerant motor-compressors EU Directive 96/61/EC – Integrated Pollution Prevention and Control (IPPC)  The IPPC Directive  Specifies “Best Available Techniques” (BAT) Examples

  10. 10. 10© 2014 Concepts ETI, Inc. All rights reserved. Problem statement: what we need to do as a workgroup Potential ORC workgroup direction  Components, subsystems then complete systems Suggested outline of work  Make a list  Adopt, modify, write new Examples given of codes, standards, and regulations Bottom line, we do not want to have to adhere to steam boiler code requirements Summary
