What aRe Your Options as a Small Coal-Fired Power Generator? Anthony (Tony) J. Cirillo, P.E.
Outline: What aRe Your Options... • R YOU-Sidelined or shanghaied?
– Environmental – Tapped potential – US electric power generation
• R YOU at a turn in the road, a dead end, an overpass...? – The many Rs of coal’s use
• Coal vs Coal • Coal vs Gas
– Combo/Hybrid: Coal-to-Gas conversions • Closing Commentary
Can YOU be economically compliant?
Do all roads lead to gas-
fueled power generation?
Coal’s Ever-Increasing
Environmental Regulation
Horizontal Drilling & Fracking
Collapse of Nuclear
Renaissance
Co-existence?
YOU may be down, but not out...
Nuclear renaissance ...not ‘in’stalled • 25 years-essentially same risks • Cost- a single nuclear unit can readily consume
10-30% of a utility’s overall value • Schedule-7-10 years • COLA Scorecard:
– 7 suspended – 9 under review – 2 issued
• Horizontal drilling and fracking
• Booming production from deposits-Marcellus, Bakken, Antrim, Barnett Basins
Fracking...shale gas bonanza
Coal use...affected by shale gas?
Advent of large scale
fracking
Coal vs Gas ...price advantageous?
Fracking effect
$2/MMBtu window
Coal’s environmental challenges Environmental regulations...ever more stringent • Oldies but goodies
– SO2, NOx, Particulate – Fugitive dust – Mercury and Air Toxics (MATS) – Effluent limitations
• Newbies, emergent or unknown – Coal ash disposal – Greenhouse Gases (GHG)
Where does ‘king’ coal go from here?
Can YOU be economically compliant?
Coal unit typical options ....
Repower, Reuse, Replace, Retire
Refuel
Retrofit
Coal-Gas
Coal units-to span the divide ...
Coal-to-Gas
Coal Gas Refuel
• Wall, corner, roof-fired boiler units can be Refueled • Examine:
• NOx and CO emissions • Final steam and exit gas temperatures • FD fan capacity • Economics/heat rate
Closing note-coal ‘shang-lined’ • 5R’s: Consider Refueling before Retirement • Current challenges No-nuclear Yes-environmental Draw-gas
• Prognosis Gas to erode coal’s dominance ...volatility Renewables forced into coal dispatch stack
• Coal-to-Gas Refueling: Stop gap, time and money saving solution
