    Google's 38 2 MW Diesel Generators in Iowa

    Data Center Knowledge pointed out due to the permiting process for Google's data center in Council Bluffs, Iowa, you can see that there are 38 diesel generators permitted for the facility with a rated power of 2919 bhp (2 megawatt)

    Emission Unit(s):

    1430 W. South Omaha Bridge Rd.

    Council Bluffs, IA 51501


    Equipment Location:


    Emission Point:

    Diesel Engine (EU 200001; 2,919 bhp; 137.9 gallons/hr)

    Control Equipment:

    Also, Data Center Knowledge has pointed out the backlogs for generators and new FCC requirements for cel networks are putting strains on the supply of generators.

    "Generator lead time for a nice 2 megawatt diesel engine is now up to a year for one generator," Josh Snowhorn of Terremark said in a panel at the NANOG conference earlier this year. "So we can build all the raised floor we want, and then sit around and wait six months for a generator."

    In an effort to keep phone and wireless networks online during natural disasters, the FCC is now requiring telecom and wireless companies to provide backup power for cell sites and remote telecom facilities.

    There is a diesel engine waste heat recovery unit based on the organic Rankine cycle. Larger diesel generator plants have a great potential to use this technology, since up to 10-15 percent of the coolant and exhaust waste heat could be converted back into producing kilowatts of power. For a typical large diesel, this might amount to up to 246 kWe / hr additional of power.

    A bigger equally big impact would be that they would not need to run the engine-driven fan radiator unit on the front of the engine for engine coolant. This saves an additional 8 percent of the engine HP. For a larger diesel, this amounts to a savings of 104 HP of engine work.

    Here are the stats:

    Waste Heat to Power: Caterpillar ( CAT 3516B TA V-16 4 Stroke Watercooled Diesel ) 1825 ekw Prime 3516B Low BSFC


    MFG: CaterpillarENGINE: CAT 3516B TA V-16 4 Stroke Watercooled DieselMODEL: 1825 ekw Prime 3516B Low BSFC

    Description: The Caterpillar is an industry prime mover for diesel engine gensets, marine, oil and industrial applications. The CAT is a good platform for waste heat recovery. The coolant to ORC power is a straight forward installation since the coolant goes directly through the heat exchanger on the Infinity Turbine, which will remove up to 60 degrees F which can reduce or replace the fan mounted radiator on the engine (avg 8 percent HP load). This can potentially allow your engine to run more efficiently.


    Organic Rankine Cycle - Global Energy Infinity Turbine using waste heat recovery from the:Caterpillar 1825 ekw Prime 3516B Low BSFC

    Power Generated From Exhaust Heat Recover: 159 kilowatts / hr

    Power Generated From Coolant Heat Recover: 87 kilowatts / hr

    Total Generated From Exhaust and Coolant Heat Recover: 246 kilowatts / hr

    Power Saved from Engine Driven Fan / Radiator: 104 HP

    Summary: 246 kWe per hour can be produced utilizing the waste heat (combined coolant and exhaust) from the Caterpillar 1825 ekw Prime 3516B Low BSFC diesel engine.

    Fuel Savings (combined exhaust and coolant heat recovery to power):-------------------------------------------------------------------------------65 Liters per hour(17 gallons per hour)1553 Liters per day (409 gallons per day)566678 Liters per year (149126 gallons per year)

    Fuel Savings Based on $1.00 USD per Liter and $4.00 USD Per Gallon:-----------------------------------------------------------------------------(a) Exhaust Waste Heat Recover to ORC Power:

    $367044 Per Year ($1.00 / liter) and $ 386362 Per year ($4.00 / gal)

    (b) Coolant Waste Heat Recover to ORC Power:

    $199634 Per Year ($1.00 / liter) and $ 210141 Per year ($4.00 / gal)

    (c) Combined Waste Heat Recover to ORC Power:

    $566678 Per Year ($1.00 / liter) and $ 596503 Per year ($4.00 / gal)

    Do you know this diesel generators? I need one, but i dont know. Can you say me if that is a good diesel generators?
