Combined Heat & Power By Mark Foley

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

Types of CHP � Large Scale � Small Scale � Micro

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

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

Prime Movers � Steam Boiler/ Steam Turbine • Gas Turbine

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

Summary of Prime Movers Electrical Output (Mwe) Typical Fuels Primary Energy Savings (%) Gas Turbine 0. 5 > Flexible Up to 30 Steam Turbine 0. 5 > Flexible 5 to 20 Spark Ignition Up to 4 Gas Up to 30 Compression Ignition 2 to 15 Up to 50 Kwe 1 to 25 Sterling Engines Kwe Micro Turbines Gas/ Heavy Up to 30 Fuel Oil Gas Up to 30 Flexible Up to 20

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

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

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