in-house maintenance capabilities.
**************************************************************************
a.
Continuous emissions monitoring system (CEMS) equipment shall be
provided as a system by a single manufacturer. CEMS, meeting
requirements of applicable federal regulations, State of [_____]
and local regulations, shall be provided for boiler in accordance
with manufacturer's recommendations and under direct supervision
of CEMS equipment manufacturer.
b.
Reported data shall include [sulfur dioxide (S02)] [oxides of
[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] [daily heat input calculation]. Nitrous oxides,
carbon oxides and particulate matter reporting shall be based on
analyzers.
c.
The CEMS equipment shall include central processing unit, printer,
hard disk drive, and floppy disk drive. Floppy disk drive shall
function as recorder. Manufacturer shall provide software to
generate required reports in format acceptable to federal, state
and local regulatory agencies. Operator interface to CEMS
equipment shall be by means of CRT display.
2.6.24.1
Gaseous Emissions Monitor
Extractive or in-situ gaseous emissions monitors shall be provided.
Combination of extractive and in-situ monitors is not acceptable. Gaseous
emissions monitors shall include automatic calibration checks. Alarm horn
and annunciator shall be provided to alarm when any monitored parameter is
out of range or gaseous emissions monitor malfunctions. Surfaces exposed
to corrosive gas of boiler shall be constructed of noncorrosive materials
such as 316 SS, Teflon or Hastelloy.
Extractive systems shall be [wet] [dry] [diluted]. Analyzing equipment for
extractive system shall be [rack-mounted] [located in a walk-in cabinet].
2.6.24.2
Flue Gas Flow Monitor
Flue gas flow monitor shall utilize the pitot tube principle to measure
flue gas flow. Flue gas flow monitor base shall be across-the-duct average
pitot tube and shall be properly designed and located to obtain
representative measurement. Differential pressure transmitters shall be
used to sense the difference between the static and total pressure of the
flowing flue gas stream. Calibrations shall be stable.
2.6.24.3
Particulate Matter Opacity Monitor
Particulate matter opacity monitor shall be based on principle of
transmissometry. Transmissometer shall include automatic simulation of
zero opacity and up scale check of calibration while boiler is in service
without dismounting monitor. Calibration check shall include analyzer
internal circuitry and electronic circuitry. Alarm horn and annunciator
shall be provided to annunciate excess opacity and system malfunction.
Monitor shall be provided with fans to keep sending and receiving lenses
pressurized and blown clean at all times.
