ON-LINE CONTINUOUS
MONITORING OF EMISSIONS FROM ELECTRO-STATIC
PRECIPITATORS (E.S.P.s) / BAG HOUSES /
CYLCONES & OTHER EMISSION CONTROL
EQUIPMENT.
Stack Monitoring for
Particulate Matter (P.M.) is greatly simplified
by the use of “STACK MONITORS”.
The sensor of the Stack Monitor is mounted
on the stack and the existing P.M. level
is determined using Gravimetric
Methods (Thimble Process / Iso-Kinetic
Process). The Stack Monitor is
then calibrated to display the
P.M. or Emission level in terms
of mg/Nm3 (or any other units of measurement
of your choice), which provides a continuous
on-line reading. A 4 to 20 mA DC Analog
Output can also be used for recording
or control purposes. Any other form of
output is also optionally available.
Since Stack Monitors can measure the
Rate of Emission, they are used for -
 |
Continuously Monitoring
the Emissions in any units
of measurement. |
|
Ensuring compliance with
the Pollution Emission Norms. |
|
Monitoring the performance
of E.S.Ps / Bag Houses &
check whether they are working efficiently
or not. |
|
Ensuring effective dust
removal from dusty environments
by monitoring the exhaust duct. |
|
Giving Early Alarm &
Indication of increase in emissions
which will help in timely redressal
of problems before they become severe,
ensure smoother production & prevent
damage to downstream equipment. |
Continuous Monitoring by Stack Monitors
has another big advantage of enabling
plant personnel to understand the production
process better – for example, if
the quality of coal supplied to the burner
has changed & subsequently there are
greater emissions for the same process
conditions, the Stack Monitors will indicate
that this supply of coal is inferior to
the earlier one.

ENERGY SAVING
BY MONITORING / CONTROLLING OF E.S.P.s
With increasing P.M. emission, more power
has to be supplied to the E.S.P.s to maintain
the P.M. emission level within permissible
limits. Due to changes in the process
conditions / parameters, the P.M. level
may fall considerably, but the E.S.P.
continues to consume the same amount of
power. The STACK MONITOR instantly detects
this, and its 4 to 20 mA DC Analog Output
can be used to reduce the power supplied
to the E.S.P. or even cut out an E.S.P.
stage, ensuring at all times that the
emission levels are within acceptable
limits. |

TO MONITOR
THE FLOW OF PULVERSIED FUEL TO THE BURNERS
The Sensor of the SOLIDS FLOW MONITOR
is mounted on the pneumatic lines conveying
the powdered coal from the pulverising
mills to the burners. The fuel feed rate
displayed for attaining a particular temperature
is a good indicator of burner efficiency.
The 4 - 20 mA DC Analog Output is used
to control the fuel rate for optimum burner
performance. Maintaining the same feed
rate in all lines ensures uniform burner
performance. Further, if flow failure
occurs in any line due to choking etc.
prompt action can be taken. Timely detection
of flow feed failures can prevent lot
of problems arising from material starvation,
e.g. - lower power generation and in extreme
cases even tripping, leading to power
failures. |

FLOW RATE
MONITORING & CONTROL OF MATERIAL FED
TO HOPPERS / SILOS / BINS etc. THROUGH
CONVEYORS / CHUTES / PIPES / DUCTS etc.
ENSURING SMOOTHER FLOW / STORAGE OF MATERIAL
& SMOOTHER PRODUCTION
SOLIDS FLOW MONITOR can provide a totalised
output (in any unit of measurement)
of powdered material fed to or released
from silos / bins / mixers etc. which
simplifies material handling, storage
and distribution. It can also be used
as a LEVEL DETECTOR,
to indicate when the material reaches
a specified level in a Hopper / Bin /
Silo. |
| 5) |
MONITORING
OF CYCLONE EFFICIENCY / OVERFLOWS
The P.M. level at the output of the cyclone
is a good indicator of cyclone efficiency.
A gradual increase in the level indicates
a deterioration in efficiency and a sharp
increase signifies an overflow condition.
Detection at this point with the use of
the SOLIDS FLOW MONITOR
prevents further problems downstream and
ensures smooth production. |

BROKEN BAG
DETECTOR FOR FILTER BAG HOUSE
Our Broken Bag Detector can not only give
an alarm AS SOON AS a Bag Tear occurs
in the Filter Bag House, it can also provide
you with an “ADVANCE WARNING SIGNAL”
before the Bag Tear actually occurs. The
4-20mA Output of this instrument will
give an early warning when the filter
bags develop small cracks / tears –
giving an advance warning of an impending
bag tear. Necessary preventive maintenance
action can then be taken. The System will
also give an indication of the occurrence
of Bag Choking. Apart from giving an immediate
indication of a Bag Tear, the System will
also help isolate which Bag Section contains
the Broken Bag or Bags. It will also be
possible to isolate the exact bags which
are torn and which need to be replaced.
Our STACK MONITORS
/ EMISSION MONITORS have several
advantages :
|
It is the only device based upon
direct measurement of the quantity
of solids / particulates. Permits
Continuous, Reliable & Accurate
Monitoring in any units of measurement. |
|
Price-wise, it is the most economical
device. |
|
It has no moving parts and therefore
it is very versatile, robust and maintenance
free. |
|
The installation of the device
is extremely simple – it is
as simple as mounting a thermocouple
in a pipe or vessel. |
|
It can be used in any kind of location
– be it safe or hazardous |
| |
With a meagre investment, the device
can prevent production loss, down
time and penalties arising out of
atmospheric contamination. |
The STACK MONITORS / EMISSION MONITORS
are the one if its only kind available and
is based upon the unique principle of Tribo-electric
technology. Incidentally, Tribo-electric
technology is the only one available today,
around the world, which enables direct measurement
of the solid particles flow in air / gases.
