Electricity Generation


Land Reclamation

project benefits
Project Benefits

Generate electricity for 110,000 homesPrinciple fuel is anthracite waste coal (culm) Advanced coal burning technology (CFB)Cleaner energy with low emissionsOperations conducted inside buildingsReclamation of abandoned mine sites

fuel capabilities
Fuel Capabilities

Facility Designed to Burn 7,000 Btu/lb Material Primary Fuel is Culm (Anthracite Waste Coal)Transition and Startup Fuel is PropaneCapable of Burning Solid Alternative FuelsFuels Fed via Conveyors to Silo or Blown into BoilerFuels Limited by Air (Stack) and Waste Permits (Ash)Fuels Limited by Borough of Northampton ResolutionNOT Capable of Burning Liquid Fuels (e.g. Oils)NOT a TSDF for Hazardous WasteNOT an Incinerator or Trash Burner

permitted fuels actual 2006 numbers in parenthesis
Permitted Fuels(Actual 2006 numbers in parenthesis)

Co-firing of Alternative Fuels w/CulmTotal Charging Rate = 105 TPH - (102 TPH) Minimum % of Fuel Mix = 50% Culm - (76% Culm) Coal (anthracite or bituminous) = 15 TPH - (0 TPH)Petroleum Coke = 32 TPH - (11 TPH) Paper Processing Residue = 25 TPH - (6 TPH)Virgin Wood Chips = 20 TPH - (0 TPH)High Carbon Ash = 50 TPH - (4 TPH)TDF (Pending Approval) = 23 TPH - (4 TPH)Propane = as needed for Start-up and Transitions

2006 fuel consumption
2006 Fuel Consumption

Total Solid Fuel = 813,651 tonsTotal Ash = 474,820 tonsCulm = 742,951 tons Coal (anthracite or bituminous) = 0 tonsPetroleum Coke = 23,939 tonsPaper Processing Residue = 37,522 tonsVirgin Wood Chips = 0 tonsHigh Carbon Ash = 6,266 tonsTDF = 2,972 tonsPropane = 260,682 gallons

cfb operation circulating fluidized bed
CFB Operation (Circulating Fluidized Bed)

CFB technology known for fuel flexibilityFuel suspended on cushion of air in boilerCombustion occurs at 1,400-1,700 deg FFuel and ash re-circulated using cyclonesAchieves higher combustion efficiencyResults in lower stack emissions Limestone injected w/fuel to reduce SOxAmmonia injected into CFB to control NOxBaghouse filters capture 99.9% of particulates

limitations on ash
Limitations on Ash

Beneficial Use Permit – WMGR068“The following carbonaceous wastes: petroleum coke, uncontaminated, untreated wood chips and other paper and wood industry wastes comprised primarily of wood fibers: and the ash generated from the burning of that waste.”Limits on As, Cd, Cr, Cu, Pb, Mn, Ni, Se, ZiSurface Mining Permits – Mod 25Coal and Ash Leachate AnalysisMaximum Acceptable Leachate ConcentrationsLimits on 17 metals, sulfate, chloride, and pH
