diameter has a weight of about 5. 3 tons/mile.
For operating expenditure (OPEX), unless more accurate
information exists, use the following assumptions (
information from defaults for IECM model prepared by Carnegie Mellon for NETL, 2015): 85 percent capacity factor,
constant dollars, 7 percent discount rate, 12 percent fixed
charge factor, 30 year book life, 34 percent federal tax rate,
4 percent state tax rate, 2 percent property tax rate, as-de-livered coal $50/ton, internal electricity rate $37/Mwh,
limestone $23/ton, water $1.2/kgal, operating labor $35/h,
waste disposal $9.4/ton, $1594/ton for rebar, and $650/cy.
Process guarantees would be on a case-by-case basis and
are for equipment availability, performance of waste product (purity and fugitive emission), power, and noise levels.
Standard wording will include a discussion of the basis of
guarantees: operating the unit according to standard operating procedures, etc.
PERFORMING FIELD TESTS,
For a typical PRB coal fired power plant with a wet FGD
and a pond, there may not be enough fly ash to form a
50 percent suspended solids waste mixture with blowdown
directly from the absorber; therefore, some degree of dewatering may be required, normally with hydrocyclones.
The precise sizing
and controllability of
the CCR handling process are dependent on
the slurry rheology.
Testing various mixtures of ash, gypsum,
These materials are mixed and allowed to cure after
which rudimentary tests including those for penetration
other residuals is
to match a dense
slurry mixer design
to a specifc plant.”
