DESCRIPTION
**************************************************************************
NOTE:
1. If fly ash conditioning or removal prior to the
precipitator is included in the design, the system
should be described.
2. If it is anticipated that the efficiency of the
precipitator will be increased by the addition of
field(s) in the future, this should be described.
3. If it is desired that the inlet and outlet
breeching be furnished and/or designed by the
collector manufacturer, it should be described.
4. Specify the ESP location and breeching tie
points.
**************************************************************************
Provide electrostatic precipitator(s) of the rigid frame type designed in
accordance with ICAC EP-1, ICAC EP-4, ICAC EP-5, ICAC EP-6, ICAC EP-7, and
ICAC EP-8 to remove fly ash from flue gas produced by a [pulverized
coal-fired boiler] [spreader stoker-fired boiler] [underfeed stoker-fired
boiler] [refuse-fired waste disposal incinerator]. Provide precipitator(s)
suitable for [indoor] [outdoor] installation. Locate the precipitator(s)
in the flue gas system between the [_____] and the [_____].
