  1. Combined Heat & Power By Mark Foley

  2. Combined Heat and Power • Combined Heat and Power is the generation of electricity and usable heat simultaneously from the same fuel input. • Electricity primarily used on-site, but can be sold back to grid. • Thermal energy used for heating/cooling or process applications

  3. Types of CHP • Large Scale • Small Scale • Micro

  4. Advantages of CHP • Generation of electricity while using heat produced. • Higher efficiency • Use of waste or byproduct fuel • On-site electric generation avoids distribution costs (7%) • Increased reliability and power quality

  5. Limitations of CHP • Must be Simultaneous Demand for Heat & Electricity • Large Capital & Maintenance costs. • Require back up of power and heat • Noise from CHP units

  6. Gas Turbine Steam Boiler/ Steam Turbine Prime Movers

  7. Reciprocating Engines Compression Engine Spark Ignition • Spark Ignition up to 4 MW • Compression Ignition – 15 MW • Exhaust Gases around 400°C • Water or Lubricating oil Systems (70 -80°C) • Ratio of 2:1 • Stirling Engine →

  8. CHP - Applications • Hotels • Nursing/Residential Homes • University Campuses • Base load of Heat & Power exceeding 4000 hours yearly • Base Electrical Load • Base Heating Load

  9. Future of CHP • CHP can help deliver the green agenda • Development of more efficient technologies • Buildings & Industries can reduce carbon footprint • Still a large capital cost

  10. Conclusion • Design of CHP system for the buildings use. • Reducing CO2 emissions from buildings. • Task for BSE to design and produce these types of efficient systems.
