Ductwork
**************************************************************************
NOTE: Ductwork velocities shall be such to maintain
self-cleaning conditions.
**************************************************************************
Ductwork upstream of the fabric filter baghouse outlets shall be designed
for a velocity of [_____] meter per second feet per minute at the design
flue gas flow, specified in paragraph entitled "Expected Flue Gas
Conditions." Ductwork downstream of the fabric filter baghouse outlets
shall be designed for a velocity of [_____] m/s fpm at the design flue gas
flow, specified in paragraph entitled "Expected Flue Gas Conditions."
Ductwork from the fabric filter baghouse outlet to the stack inlet shall be
designed to withstand a transient internal pressure (80 percent of yield
strength) range of minus 2490 Pa to plus 7470 Pa 10 inches Water Column
(WC) to plus 30 inches WC without permanent deformation of any structural
member at yield or in buckling.
