Title
Particulate Matter Collection Equipment
ASME International
Publication Date:
Jan 1, 1991
Scope:
OBJECT AND SCOPE
The object of the test is to determine the performance characteristics
of equipment designed to
collect particulate matter from a gas stream. This Code specifies
methods for determining the
performance of the equipment with regard to the following:
(a) overall mass collection efficiency of the equipment;
(b) particulate matter concentration at inlet and outlet of collector;
(c) efficiency of collection according to size of particle;
(d) resistance to gas flow, i.e., the total pressure drop across the
equipment;
(e) quantity of gas passing through the equipment; and
(f) power consumption of the collection equipment.
The rules and instructions included in this Code are for the
particulate matter collection
equipment proper, as indicated by para. 1.1. If the scope of the test
includes any auxiliary
apparatus, it will be necessary to consult other ASME codes, as
applicable.
The determination of the particulate matter count, extensively used as
a measure of atmospheric
particulate matter pollution, is outside the scope of this Code.
This Code cautions against the extrapolation of the performance of a
complete particulate matter
collection installation on the basis of testing only a single unit of
multiple unit equipment.
Should specific directions given in this Code for any particular
measurement differ from those
given in other ASME Performance Test Codes for similar measurements,
the instructions of this Code
shall prevail, unless otherwise agreed by the parties to the test.
This Code specifies the desired conditions and procedures for
obtaining valid and accurate test
results. Factors affecting overall test accuracy and validity are
considered in paras. 5.4 and 5.5.
