SYSTEM OVERVIEW

General The OPM 3000 Opacity/Dust Density Monitor provides continuous, low

maintenance, precision measurement of opacity and optical density in

industrial applications. It is a cost-effective instrument that serves as an aid in

operating pollution and/or process control equipment.

Opacity refers to the amount of light being scattered or absorbed by particles

in the light beam path. An opacity or dust density transmitter (also called a

transmissometer) measures the particulate level of stack emissions. One of

the most common reasons for measuring opacity is to comply with

Environmental Protection Agency (EPA) or other national requirements.

Federal regulations for new emission sources and many state regulations for

both new and existing sources specify maximum limits for stack emission

opacity.

A transmissometer can be used in a variety of applications. Those

applications include monitoring the efficiency of emission control systems,

detecting broken bags in baghouses, and determining the time rapping cycles

for electrostatic precipitators. Another application is to gauge the

effectiveness of injecting flue gas conditioning agents used to improve

electrostatic precipitator performance.

Opacity data can also serve as a rough indicator of combustion efficiency.

Extreme changes in opacity may indicate inefficient combustion or boiler

problems. Because the transmitter gives accurate, immediate response data,

corrective actions can be taken as soon as problems occur. This data serves

not only the compliance requirement of pollution regulation standards but also

as a means to achieve improved efficiency and operating profit.

Originally, a trained smoke reader determined the particulate level of stack

emissions solely by observation. The opacity of the plume was judged in

reference to a standard Ringelmann scale of 0 to 5. These determinations

tended to be influenced by several sources of error such as sky haze, sun

position, and the subjective determination of the observer. These sources of

error, especially at lower opacity levels, can produce highly variable readings

even when performed by a trained observer.

OPM 3000 System

Features

Transmissometer/Retro Reflector

The OPM 3000 is a precision, double-pass, dual beam Transmissometer that

consists of a transceiver (transmitter/receiver) mounted on one side of a stack

or duct and a passive reflector mounted on the opposite side. The light

source, photo detectors and all measurement/reference optics used in opacity

measurement are housed in the transceiver.

The function of the reflector is to return the measurement beam to the

detector in the transceiver, creating a double pass across the process stream.

The standard reflector is used for measurement path lengths up to 15 feet

(4,6 m). For longer path lengths, maximum 60 feet (18,3 m), reflectors, optical

parts and electronics will vary.

Figure 1-2. Transceiver

Assembly with Weather Cover

Control Unit

Mounted in a control room environment, the OPM 3000 control unit provides

instrument control functions (Section 4: Normal Operation for details).

Optional Air Purge Weather Cover System

The transceiver and reflector may be mounted in weather covers. The

weather covers are fairly compact to allow movement around them even on a

three-foot walkway or platform. They protect the stack-mounted components

from dirt, moisture, stack temperatures within the specified ambient

temperatures limits, and errant air currents around the stack.

The air purge system constantly circulates air past the optical window. The

airflow is directed through the hose to an air plenum on the stack side of the

optical window. The airflow in the air plenum area results in reduced pressure

and increased velocity. This venturi effect tends to continually draw the air

around the optical window into the purge air stream, thereby keeping the lens

clean for long periods.

Alignment System

The OPM 3000 includes a built-in through-the-lens alignment system. The

alignment target can be viewed through a window on the transceiver.

Adjustments to changes in alignment are provided by a 3-point alignment

system, which is integral to the air plenum.

Cabling

The standard cabling used between the stack-mounted units and the control

unit is at a minimum 2-pair, #22 AWG, twisted, shielded cable. More pairs or

larger than 20 AWG is acceptable.

Normal Mode of

Operation

The dual beam measurement system has a stack mounted transmissometer

sensor system that consists of an optical transceiver mounted on one side of

the stack and a retro reflector mounted on the other (Figure 1-3). To avoid

errors due to ambient light, the lamp is electronically modulated and projects

a collimated beam of light, which is split into a reference beam, and a

measurement beam by an optical beam splitter. The reference beam is

directed to the reference detector (RD). The measurement beam is projected

across the stack to a retro reflector that returns the beam back across the

stack to a beam splitter and directs the measurement beam to the

measurement detector (MD). A portion of the returning light is also sent to the

TTL (Thru The Lens) bulls-eye target viewed through a window provided at

the rear of the transmissometer. The bulls-eye is used to correct changes in

alignment and is unique in that no moving parts are used.

The ratio of the measurement and reference detectors is used to provide a

transmittance

2

(T

2

) signal. Because the same light source is used for both

detectors, and a measurement / reference ratio is used throughout for the

calculations, the monitor is insensitive to variations in light intensity. Since all

measurements are made on a ratio basis, all resulting computations are

independent of the absolute intensity of the light source or contamination of

the optics associated with the collection and focusing of the energy from the

lamp. The (T

2

) signal is converted to a current format and sent to the control

unit for processing. At the control unit the signal is processed to read 0-100%

opacity, and provide alarms and outputs.

INSTALLATION

CONSIDERATIONS

Choose an Installation

Site

The primary considerations for choosing a site for the OPM 3000 are

accessibility, ambient environmental conditions, and obtaining a

representative sample of the process. The following general guidelines should

be considered.

Accessibility Locate the instrument where it will provide safe access for periodic

maintenance and inspection. A platform or walkway is required for access to

the sensors and weather covers. The optimum condition is to have the

mounting flanges and weather covers approximately 5 feet (1,5 m) above the

floor. A minimum of 12 in. (305 mm) from the bottom of the weather cover to

the floor is required in order to remove the air filters.

Clearance Installation clearances for the transceiver, retro reflector and optional weather

covers are shown in Figure 2-1.

Environment Locate the stack-mounted units in an area with ambient temperatures

between -40

o

to +130

o

F (-40

ο

to 54

o

C). (Consult the factory for other

temperature ranges.) Areas that are clean and dry are desirable. Avoid areas

with condensation.

Maintenance intervals are directly related to the installation environment.

Intervals can vary from 2 to 3 months in fairly clean environments, to twice a

month in dirty environments. Lens cleaning is a function of the ambient

conditions and cleanliness of the purge air.

Choose a location that will minimize excessive vibration or shock.

Locate the control unit in an easily accessible area with temperatures

between +32

o

to 122

o

F (0

o

to 50

o

C). To permit the operator to read and/or

change controls, the unit should not be mounted higher than five feet from

floor level.

Sample Area To achieve a representative sample, the accepted practice is to have the

measurement path of the instrument directly in the center of the stack. An

area should be chosen where the gases are not stratified in the stack or duct.

When installed near a bend, install the transceiver in the plane defined by the

bend; refer to "Regulatory/Process Considerations". Avoid locations where

large amounts of condensed water is present.

Stack Exit It is recommended to locate the transceiver at least two stack diameters from

the stack exit.

Regulatory/Process

Considerations

The EPA has established the following guidelines for choosing an opacity/dust

density monitor installation site:

1. Locate the transmitter across a section of a duct or stack that will

provide a particulate matter flow through the path of the transmitter

beam representative of the duct or stack flow.

2. Ensure the transmitter location is down-stream from all particulate

control equipment.

3. Locate the transmitter as far from bends and obstructions as practical.

4. If a transmitter is to be located less than 4 duct diameters downstream

from a bend, install the transmitter in the plane defined by the bend, as

shown in Figure 2-2.

5. Ideally, locate the transmitter eight to ten stack diameters upstream from

the stack exit and three to five diameters downstream from any bends,

junctions, or other constrictions in the stack or duct.

For best results, mount the transceiver and retro reflector modules so

the light beam is exactly perpendicular to the stack or duct and the

beam goes through the center. Do not install the transmitter

downstream of a wet scrubber. The water droplets introduced to the gas

stream by such equipment will interfere with the opacity readings. For

an accurate measurement under these conditions, choose a location

upstream from a wet scrubber or a location downstream from the

scrubber where the water droplets are vaporized by the reheating of the

gas.

MECHANICAL

INSTALLATION

NOTE

The beam of the instrument must be kept in a horizontal plane; the transceiver

cannot be rotated more than ±10

o

from vertical. The weather covers must be

installed vertically level.

Installation of Stack

Flanges

Mounting on stack diameters under 6 feet

NOTE

Flanges should be mounted approximately 5 feet (1,5 m) up from the deck of

the platforms, roof or walk way.

1. Form two mounting holes in the stack at locations specified in

"Installation Considerations". Holes must be on the same horizontal and

vertical axes. A liquid level can be used to ensure that modules are

installed on the same horizontal plane.

2. Insert a piece of 2-1/2 in. (64 mm) pipe through the mounting holes.

Make sure pipe is protruding far enough to allow installation of the 3 in.

pipe flange assemblies over each end (Figure 2-3, Stacks Under 6 Feet

Across).

NOTE

The customer is required to supply and install two 3 in. IPS flanges at eye

level directly across from each other.

3. The flanges must be aligned so that the total deviation of the light

source flange relative to a common centerline does not exceed ±1

o

and

the retro reflector flange does not exceed ±3

o

. Any deviation within

these limits can be countered during the installation and alignment of

the light source and retro reflector with the system's alignment

adjustments.

4. Weld the pipe flanges to the mounting nipples, as shown in Figure 2-4.

5. Install the pipe flange assemblies into the stack / duct wall. The flange

should be 6 to 8 in. (152 to 203 mm) from the stack or insulation

(Figure 2-4).

Mounting on stack diameters over 6 feet

1. Form two mounting holes in the stack at locations specified in

"Installation Considerations". Holes must be on the same horizontal and

vertical axes. A liquid level can be used to ensure that modules are

installed on the same horizontal plane.

2. Locate one 3-1/2 in. (89 mm) diameter hole (large enough to accept the

3 in. mounting nipple) and the other hole approximately 1/2 in. (13 mm)

diameter, directly across from each other.
