available. The traditional differential pressure
technique specified used familiar equipment that can
be maintained by plant personnel. This type of
measurement device has reliably satisfied regulatory
requirements. The possible use of other
technologies should include a thorough investigation
of flue gas flow monitor regulatory requirements and
inhouse maintenance capabilities.
**************************************************************************
a.
Continuous Emissions Monitoring System (CEMS) equipment shall be
provided as a system by a single manufacturer. A CEMS, meeting
the requirements of applicable federal, State of [_____] and local
regulations, shall be provided for each boiler in accordance with
manufacturer's recommendations and under the direct supervision of
the CEMS equipment manufacturer. Before acceptance of the
installation, the Contracting Officer shall be furnished a written
test report which provides documentation that the CEMS equipment
passed factory and field certification test required by federal,
state, and local regulations.
b.
The reported data shall include [sulfur dioxide (SO2)] [oxides of
nitrogen (NOX)] [carbon dioxide (CO2)] [and] [particulate matter
(PM)] and other information required by Federal, state, and local
regulations. SO2 reporting shall be based on [analyzer
measurement] [fuel flow and percent sulfur calculation]. Nitrous
oxides, carbon dioxide and particulate matter reporting shall be
based on analyzers.
c.
The CEMS equipment shall include the central processing unit,
printer, hard disk drive, and floppy disk drive. The floppy disk
drive shall function as a recorder. The manufacturer shall
provide the software to generate the required reports in a format
acceptable to the Federal, state and local regulatory agencies.
The operator interface to the CEMS equipment shall be via CRT
screen.
2.11.2.1
Gaseous Emission Monitors
Extractive or in situ gaseous monitors shall be provided. A combination of
extractive and in situ monitors is not acceptable. Gas monitors shall
include automatic calibration checks. An alarm horn and annunciator shall
be provided to alarm when any monitor parameter is out of range or a
gaseous monitor malfunctions. The surfaces that are exposed to the
corrosive gas of the boiler shall be constructed of noncorrosive materials
such as 316 SS, teflon or hastelloy.
a.
In situ monitor shall be mounted on the ductwork at the location
[shown on the plans] [recommended by the manufacturer]. The situ
system shall not be affected by the presence of particulate matter
in the flue gas.
b.
Extractive systems shall be [wet] [dry] [diluted]. Analyzing
equipment for the extractive system shall be located in a walk-in
cabinet. The equipment shall be arranged to provide access for
maintenance. Extractive system sampling between the probes and
the analyzers shall be heat traced to maintain the temperature
recommended by the manufacturer when the ambient temperature is
[_____] degrees C F. Probes shall be mounted on the ductwork at
