1.9.5
Breeching
Provide breeching, stiffeners, bracing, supports, hangers, supporting
steel, expansion joints and heat insulation between the [_____] and
[_____]. Design the breeching to withstand internal pressures between plus
3735 to minus 6225 Pa 15 to minus 25 inch water gage. Include turning vanes
in breeching as recommended by the report on model test. Provide
self-cleaning type breeching to prevent dust accumulation. Provide
expansion joints to give the breeching sufficient flexibility under thermal
changes. Provide suitable supports and guides to eliminate transverse
loading of flexible expansion joints.
1.9.6
Coordination
Coordinate design parameters and controls of precipitator between
precipitator manufacturer and manufacturers of equipment which will
interface with, or affect, system operation. Design the precipitator for
operation with the [boiler] [incinerator] [and the mechanical cyclone type
dust collection] specified to assure that the collection efficiency
specified is attained.
1.9.7
Electrostatic Dust Collector System
Submit operation and maintenance data for electrostatic dust collector
system in accordance with Section 01781 OPERATION AND MAINTENANCE DATA.
SECTION 15862N
