  2. Combined Heat and Power (CHP) • What is CHP? • Efficient way to generate heat and power together • What does CHP provide to the rest of the project? • Electricity • Cooling water • Why is CHP needed? • Improve fuel efficiency, power quality, and energy cost predictability • Reduce grid investment, ratepayer investment, and system vulnerability • Support competitive electric power industry structure • Our Goal • “To optimize energy production and consumption of the whole plant .“ - Prof. Perl

  4. Power Block

  5. Power block- Gas Turbines Microturobines - Power output ranges 50-300kW, with the electrical efficiency 25-30%( in recuperated and 15% in unrecuperated), basically very small combustion turbines( turbocharchers) Aeroderivative - theyare usually more expensive than products designedand handle load changes more quickly no heavy construction. Industrial - are exclusively for stationary power generation and are available in flexible capacity range. They are generally less expensive

  6. Power block- Steam Turbine Backpressure Steam Turbine (non-condensing steam turbines) – produces less useful work than the condensing turbine but the steam exhaust at above atmospheric pressure used for other steam applications (Power generation efficiency 15-35%) Condensing Steam Turbine - generally used in CHP systems, produces maximum useful work per lb of steam input (Power generation efficiency 30-40%)

  7. Cooling Water

  8. Boiler Feed Prep • What is boiler feed prep? • Provide pure water for boiler • Why do we need boiler feed prep? • Maximize life of boiler, steam turbine, and condenser • Maximize process performance and productivity • Reduce operation costs and maintenance expenses • Design Basis • Production: Ensure provide enough water for boiler • Feedstock: Reclaimed water from cooling water system • Outcomes: removal or control of Ca, Mg, Si, Al, high alkalinity, bicarbonate alkalinity • Blow-Down

  9. Boiler Feed Prep • Main Processes • Clarification • Filtration • Reverse Osmosis • Ion Exchange • Competing Companies • GE • Nalco • Siemens • Veolia

  10. Q & A
