baghouse due to the finer particulates but the
mechanical collector will add 498 to 747 Pa 2 to 3
inches WC to the overall system pressure drop. Use
a mechanical collector upstream of a baghouse only
if necessary to prevent glowing embers (from
incinerators) from burning bags.
**************************************************************************
Design baghouse(s) for operation with [Section 15861N MECHANICAL CYCLONE
DUST COLLECTOR OF FLUE GAS PARTICULATES] [mechanical cyclone dust
collector(s) manufactured by [_____], Type [_____], Model Number [_____]].
The mechanical dust collector [is specified to have] [was designed for] an
outlet particulate emissions loading no greater than [_____] grams per dry
std cu meter grains per dry std cu ft.

Inlet Gas Conditions
**************************************************************************
NOTE:
1. Baghouse manufacturer must know the expected
range of inlet gas conditions. For operation
sensitive at reduced load applications, eg. stokers
and incinerators, include upset partial load
conditions. This information can best be supplied
by the boiler or incinerator manufacturer;
compensate for system component effects between the
baghouse inlet and boiler, or incinerator, outlet.
2. For existing installations, conduct source
testing to determine baghouse inlet gas conditions.
Use EPA, 40 CFR 60, Appendix A, Method 1 through
Method 4, to determine gas volume flowrates. Use
ASME PTC 28 to determine particulate size
distribution. For particulate loading only, use
EPA, 40 CFR 60, Appendix A, Method 5, or Method 17.
3. For new installations, obtain inlet gas
conditions from the manufacturer. If this is not
possible, estimate using EPA AP-42 emission factors.
Make corrections for expected combustible content.
