Design features:
Arranged with a water-cooled dry-bottom furnace, and superheater, reheater, economizer and air
heater components – the Downshot design features an enlarged, refractory-lined furnace for low rank coals resulting in a hotter furnace to sustain combustion.
Capacity, steam output:
About 700,000 lb/h (90 kg/s) to a maximum that may exceed 7,000,000 lb/h (880 kg/s).
Pressure:
Subcritical, usually 1800 to 2400 psi (12.4 to 16.5 MPa) throttle pressure with 5% overpressure
capability.
Superheater and reheater outlet temperatures:
As required, usually in the range of 1000 to 1050F (538 to 566C).
Fuel:
Coals with low volatile matter content, particularly anthracites, that are difficult to ignite and burn.
