2 24 February 2017 PARTNERSHIP Industry - Academia Presentation Title 2

3 Manik Ventures is the HERU SPV 24 February 2017 Waste & Resource Management Company Experienced sector professionals across waste, recycling and energy: MRF design, build, operate Large scale international material brokers Infrastructure development Multiple recycling sites in the UK Previous experience of developing and selling recycling infrastructure to FTSE companies Entrepreneurial and forward thinking 3

4 24 February 2017 Applied heat pipes and heat pipe-based heat exchangers for low, medium and high temperature applications Unique expertise in academia and the industry with direct support from research councils and various UK and international industrial partners Development of novel designs for recouperators, steam generators & condensers and flat heat pipes 4

5 24 February 2017 THE CHALLENGE Presentation Title 5

6 24 February 2017 WASTE MANAGEMENT Essential industry with centuries old practices 6

7 The Vision 24 February 2017 A Home Energy Recovery Unit that facilitate the following tasks: Treat Municipal waste at source no collection Transform waste from hazardous status to inert fuel Runs using a standard13amp heater with no additional infrastructure for homes. Pyrolysis maximum working temperature of less than 300 C to prevent dioxin formation Can deal with any municipal waste configuration Can be a stand-alone domestic water heating system or as a pre-heater Scalable 7

8 24 February 2017 Pyrolysis It has been around for a long time Has been largely unsuccessful in the waste treatment due to technological challenges The answer: The Heat pipe technology 8

9 24 February 2017 Heat Pipes What are they? 9

10 Heat Pipes 24 February 2017 Low temperature heat pipe Working fluid High temperature heat pipe 10

11 Heat Pipes 24 February 2017 Multiple Redundancy Each pipe operates independently so unit is not vulnerable to a single pipe failure This prevents cross contamination each heat pipe acts as an additional buffer between the two fluids Better fouling management Use of smooth pipes allows exchangers to be used in high particulate or oily applications Ease of Cleaning & Maintenance Can be maintained in situ (no uninstall) Manual/automated cleaning systems Isothermal Operation no hot or cold spots Eliminates cold corners and condensation Allows greater energy recovery Better longevity for thermal oil Robust Materials and Long Life Design allows pipes to freely expand and contract, thus no thermal stress on structure Thick pipe walls resist erosion/corrosion Intermediate Pipe Working Temperature Allows higher exhaust temperature limits on some applications Highly Scalable, Customisable & Configurable Modular design allows on site assembly Can be designed for future expansion, to meet specific application or operational needs Reactivity Fast reaction time, offers different control options and suitable for sensitive apparatus: does not require preheating Passive devices No need for pumping energy to drive the heat transfer process through the heat pipe 11

12 Cross flow HP units: Gas to air 24 February 2017 Hot exhaust Preheated combustion air Cooled exhaust to the new stack Cold combustion air Heat pipe heat exchanger 12
