Ruston, 16RK3C, 5 MW, 900 RPM, Natural Gas / Tail Gas

Description

  1. Overview
    1. Inventory number: E-3529
    2. 5 megawatt power station powered by two brand new rebuilt V16 Ruston motors with 1999 Baylor ends that have never been used.
    3. Motors run on natural gas at 900 rpm.
    4. All manuals and commissioning reports from the last time the system was run are included.
    5. Entire system has less than 100 hours running time.
  2. Engine Specifications
    1. Two identical tail gas engines manufactured and rebuilt by Clarke Energy in England.
    2. Consist of modified Ruston 16RK3C diesel engines with directly coupled Baylor 2.2 MW generators mounted on a common bed frame.
    3. Engines have modifications for operating on tail gas, a low calorific value waste gas; can also operate on natural gas.
    4. Engine is a Ruston 16RK3C, a V16 engine with two banks of eight cylinders in a 45 degree vee formation.
    5. Engine is air start and requires 375 psig air supplied and distributed to the A bank of cylinders.
    6. Engine is water cooled and fitted with electric heaters and thermostat controls for preheating.
    7. Engine skid has a water/water heat exchanger for cooling the closed circuit cooling water.
    8. Lubrication is by a pressure lubrication system with both an engine driven pump and an auxiliary electric pump.
    9. Skid has a water cooled oil cooler, twin oil filters with cleanable stainless steel elements, and thermostatic controlled electric heaters for preheating engine oil.
    10. Oil capacity is 120 imperial gallons.
    11. Original inlet and exhaust manifolds have been removed and replaced with a purpose built system for handling and mixing tail gas and air.
    12. Air system is turbo charged with twin Caterpillar turbochargers with an identical set up for the tail gas.
    13. Both gas and air are cooled in water cooled intercoolers before being ratioed and mixed together just prior to each cylinder inlet valves.
    14. Engines were controlled by individual control panels using a Deep Sea engine controller with a Barber Colman Pow-R-Con load controller including auto synchronisation.
  3. Engine Modifications
    1. Compression ratio reduced from 11.7:1 to 8.8:1 by installing non standard pistons; cylinder diameter is 10 in and piston stroke 12.
    2. Valves and seats were changed.
    3. New cams with modified profile.
    4. Standard injectors replaced with very small injectors to act as a liquid spark plug for igniting the tail gas.
    5. A special very high cetane start fuel was required to start the engines, switched to standard diesel once the engine was hot.
  4. Generator Specifications
    1. Baylor generator is a single bearing unit; the drive end is directly bolted to the engine flywheel.
    2. Nameplate rating: 2500 kW, 3125 kVA, power factor 0.8, 4160 V, 434 A, 3 phase, 60 Hz, 900 rpm.
  5. Condition
    1. Less than 100 hours running time on the system.
