2.  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.  Large Scale  Small Scale  Micro

4.  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.  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

7.  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 Spark Ignition Compression Engine Stirling Engine →

9.  Base load of Heat & Power exceeding 4000 hours yearly  Base Electrical Load  Base Heating Load  Hotels  Nursing/Residential Homes  University Campuses

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

11.  Design of CHP system for the buildings use.  Reducing CO 2 emissions from buildings.  Task for BSE to design and produce these types of efficient systems.
