  2. OVERVIEW • COMBINED HEAT & POWER (CHP) • DEFINITION • TYPES OF CHP SYSTEMS • BENEFITS OF CHP • UMC-RH (Rizk Hospital)/ HEAT RECOVERY ON GENERATORS • ENERGY NEEDS • HEAT RECOVERY SYSTEM • SAVINGS

  3. WHAT IS CHP? • CHP = COMBINED HEAT & POWER • CHP is the use of a heat engine to generate simultaneously electricity and useful heat. • It is a way to use heat usually wasted when electricity is generated. It recovers waste of heating, cooling or dehumidification.

  4. TYPES OF CHP SYSTEMS CHP comes in a variety of configurations to match the needs of energy consumers: • CHP FOR HEATING Heat and Power to multiple customers in city centers, towns, hospitals, … and other zones where there is high demand of heat. • TRIGENERATION Also known as combined cool, heat and power (CCHP). Heat is cooled by absorption chillers linked to the CHP system. Heat • INDUSTRIAL CHP High value of heat (at the temperatures and pressures required by industry) along with electricity. produced is cooled by absorption chillers linked to the CHP system

  5. BENEFITS OF CHP • HIGH OVERALL EFFICIENCY UP TO 80% OR MORE at the point of use CHP system • SAVINGS UP TO 30% of ENERGY BILLS • SAVINGS UP TO 30% of CARBON EMISSIONS • FLEXIBLE AND RESPONSIVE HEAT SUPPLY the thermal energy (heat or cooling) produced by CHP can be easily stored and later delivered to meet demand

  6. UMC-Rizk HospitalHEAT RECOVERY ON GENERATORS FUME

  7. ENERGY NEEDS FOR HOSPITAL • HOSPITAL IS AN EXCELLENT CANDIDATE FOR A TRIGENERATION SYSTEM. IN OUR CASE, DESIGN IS APPLIED ONLY ON GAS EXHAUST TO COVER THE HEATING DEMAND. • THERMAL ENERGY - HOT WATER DEMAND FOR: • HOT WATER TANKS • LAUNDRY • HOSPITAL MEDICAL EQUIPMENT • STERILIZATION • SPACE HEATING/COOLING SYSTEM • ABSORPTION CHILLERS • OTHER SERVICES

  8. FUEL FOR GENSET 100% ELECTRICITY 35% ELECTRICITY 35% GENSET PERFORMANCE RATES LOSSES 65% RADIATOR 20% FUME 30% RADIATION 15%

  13. SEASONAL PERFORMANCE

  14. HOURLY MEASUREMENTS MEASUREMENTS TAKEN DURING OPERATION OF TWO GENSETS

  15. DAILY MEASUREMENTS MEASUREMENTS TAKEN DURING OPERATION OF ONE GENSET

  16. SAVINGS • PERFORMANCE • 2 X Genset650KVA each 2 X 300KW Heat Exchanger each (at 100% electricalload) 3Hours/Day Operation 80% Loading Factor • Exhaust Flow Gas Rate: 2705 Kg/hr • Exhaust Entering Temperature: 568˚C • Exhaust Gas Leaving Temperature: 220˚C • Water Flow Rate: 12.5m3/hr • Entering Temperature: 70˚C • Leaving Temperature: 90˚C

  17. SAVINGS • SAVINGS • Annual Hours of Operation: 3 hours / day x 365 days = 1095 hours of operation • Annual Capacity Recovered at 80% load: 2 x 300 KW x 0.8 x 1095 hr = 525 600 KWh / year • Input Fuel Energy Saved (90% eff.): 584 000 KWh / year • Fuel Cost per 1000 L Diesel: 1000 $ • Hourly Savings: 44.4$ • Less charges on boilers 10000$ • Fix Annual Cost: - Maintenance Cost - Special Cleaning Workmanship - Electricity for pumps - Spare parts • NET SAVINGS: - NET TOTAL YEARLY SAVINGS ~ 60,000$ - PAYBACK PERIOD ~ 3.5 YEARS
