Description

  1. Overview
    1. Cogeneration plant
    2. 3.2 MW
    3. Used
    4. Year 2009
  2. Engines and Generators
    1. Four Caterpillar G3516 SITA engines
    2. Mated to Caterpillar SR-4 or SR-4B generators rated at 800 kW, 480 V, 1200 A
  3. Chillers
    1. Two 420 ton Trane absorption chillers
    2. One 630 ton Trane centrifugal chiller
    3. One Recold chiller unit
  4. Heat Recovery System
    1. All energy is recovered through a system of exhaust and cooling water heat recovery units
    2. Units have wet exhaust systems that capture exhaust heat
    3. Cooling water heat is captured in a shell and tube heat exchanger (one for each generator)
    4. Exhaust gas temperature is approximately 800°F
    5. Block water enters the heat exchanger at 205°F
    6. After the heat exchanger, water enters the two absorption chillers at 230°F
    7. Engine intake water is approximately 200°F after processing through the chillers
  5. Cooling System
    1. The two generator turbos are cooled through a closed cooling loop with a Recold unit
  6. Fuel and Design
    1. Plant is designed to run on natural gas
