continuous emission monitoring
Biofuel combustion plants
The biofuel industry has been witnessing a steady growth over the past few years. With production
capacity growing every year, biofuel combustion plants constitute an important part of our energy future.
Driven by legal regulations regarding greenhouse gases and pollutants, as well as operators needing better
information on thermochemical processes for efficient plant operation, the biofuel market demands a
complete Continuous Emission Monitoring System (CEMS) designed especially for this application.
With NA-CEMS Norsk Analyse
AS offers a pre-engineered and
field-proven standardized system
fulfilling market requirements.
The purpose of NA-CEMS is
to monitor the concentration
of nitrogen oxides, carbon
monoxide, sulphur dioxide,
oxygen and dust in flue gas.
Additional gases may also
be monitored depending on
the biofuel type and on local
environmental legislations.
Due to its modular design, the
NA-CEMS provides simple
configuration facilities. Starting
with a mounting frame with a
sample preparation system,
it is possible to add additional
units as options. These include:
• Sampling probe with weather
protection hood
• Heated sample gas line
• Analysers
• Air-conditioning unit
• Nitrogen dioxide/nitrogen
oxide converter
• Sample preparation extension
for an additional ULTRAMAT
23 analyzer
• In-situ dust and flow monitors
The standardized NA-CEMS is
prepared for the well-proven
Siemens ULTRAMAT 23 analyser.
This instrument offers continuous
measurement of three infrared
active components and oxygen in
a single, compact analyser.
The automatic calibration function
utilizes ambient air for zero and
span calibration. This ensures
maximum ease of use and
minimum maintenance attention
for effective, economic and reliable
plant operation.
After analysis, the data is
transferred to the CombiLab
acquisition system for further
processing and reporting.
EnviLoop CombiLab is a
powerful and flexible software
tool for logging, reporting
and handling of measured
environmental data. It may be
configured for small-scale tasks
as well as for large plants with
hundreds of measuring points.
Both history and real-time data
are presented on the customer’s
control system computers. The
operator may also create reports
with self-defined measurement
Waste incinerators and large combustion plants
The incineration process converts waste materials into dust, ash, flue gas and heat. As incineration of both
hazardous and harmless waste may cause emission of substances which may pollute air, water and soil,
waste incineration plants are subject to legal regulations.
Authority requirements on operating conditions for the waste treatment process are often more stringent
than for traditional power plants. Norsk Analyse AS will thus provide a Continuous Emission Monitoring
System (CEMS) to ensure your compliance with environmental regulations and directives. This system is
also perfectly suited for emission monitoring of large combustion plants.
The Gasmet CEMS FTIR
measuring system is specially
designed for continuous
monitoring measurement of
emissions from waste incinerators and large combustion plants.
It is an ideal tool to use for
measuring trace components of
pollutants in wet, corrosive gas
A large number of gaseous
components can be monitored,
such as carbon dioxide, carbon
monoxide, nitrogen oxides,
sulphur oxides, hydrogen
chloride, hydrogen fluoride,
ammonia, methane and other
hydrocarbons. Measured
components and calibration
ranges can be changed according
to customer specifications.
The Gasmet CEMS uses a hot
and wet sample extraction
system, operating at 180 °C. After
extracting the sample from the
stack, it passes through heated
lines to the heated sample cell.
Particulate matter is removed, but
not moisture. This ensures that a
representative sample of the flue
gas is measured at all times, and
not a dried or diluted version.
In-situ flue gas analysers can
also be provided. The Ametek
Thermox WDG 1200 In-situ is a
rugged, reliable flue gas analyser
for net oxygen analysis. Its main
use is to monitor and control
the combustion efficiency of
incineration and processes.
The analyser design allows the
entire sensor assembly, including
the heater, to be removed without
disturbing the outer protection
tube which remains in the process.
This makes field service fast and
The rack includes all power
connections and temperature
controllers for heated lines and the
heated sample probe.

outputs are standard.
DURAG environmental monitoring products
DURAG develops and manufactures products in the field of environmental measuring technology for
measuring and monitoring of dust concentration and opacity, total mercury concentration and flue gas
volume flow. The products are used worldwide in power generation plants and the process industry, such
as fossil fuel power stations, waste incineration plants, refineries, chemical processing plants, cement
works, the lime industry, the steel industry, filter and dust extraction plants.
When selecting a suitable device,
both general specifications, such as
desired measurand or measuring
range, and special plant conditions
at the measuring location must
be taken into account. Standard

NEO LaserGas Monitors
NEO Monitors supplies reliable gas analyser for true continuous in-situ monitoring. Single Path Monitors
are designed for measurements across stacks, ducts and reactors. Typical path lengths are from 0.5 to 20
metres. By-pass and extractive configurations are also possible.
The LaserGas in-situ analysers
utilize the Tuneable Diode Laser
Absorption Spectroscopy (TDLAS)
technology. This is an optical noncontact measurement technique
employing solid state laser
The sensor therefore remains
unaffected by contaminants and
corrosives, enabling real-time
measurements in the process.
The sensor thus does not require
regular maintenance.
The absence of extractive
conditioning systems further
improves availability of the
measurement and eliminates
errors related to sample handling.
Main features:
• Response time down to one
• No gas sampling: In-situ
• No interference from
background gases
• Stable calibration, no zero drift
• Applicable for many process
conditions: High temperature,

for maintenance and filter
Gas must be transported at
a steady pressure and flow.
Bühler’s unique bellows
pump design ensures this
regardless of filter loading,
both for heated and un-heated
In order not to bias gas
measurements, a stable dew
point is required for dry basis
or standard condition systems.
Bühler sample gas coolers
provide the most stable dew
point in the industry.
Biogas production plants
Biogas is produced from a variety of renewable organic matters as animal slurry, paper waste or aquatic
weeds. This gas consists mainly of methane and carbon dioxide, but may also contain small amounts of a
wide range of other components.
As some of the components produced may be corrosive, poisonous or malodorous, it is therefore essential
to have a good knowledge of the biogas produced. For such purposes, both a standardized wall-mounted
system and handheld gas analysers can be provided by Norsk Analyse AS.
The Siemens Set BGA (biogas
analyzer) is a standardized
system for stationary, continuous
operation for the analysis of
landfill gas, sewage gas and
biogas. This system contains
all the required components for
the relevant application, from
gas sampling to operator control
and display units in a compact
The standardized complete system
has a modular configuration
and can thus be used at various
measuring locations for different
measuring tasks. This field-tested
system is based on the wellproven ULTRAMAT 23 analyser.
Efficient production and
optimum operation of the plant
largely depends on continuous
monitoring of the biogas
composition. The basic version
of the Set BGA analyses methane
and carbon dioxide using the
ULTRAMAT’s infrared analyser.
The concentrations of oxygen and
hydrogen sulphide are optionally
measured using electrochemical
sensors. All measured values are
converted to 4-20 mA analogue
output signals.
The Geotech 5000 series
comprises portable biogas
and landfill analysers for gas
measurements. They are easy
to use and calibrate, benefiting
from their market leading
reliability, thus helping you to
standardise monitoring routines,
whilst supporting environmental
legislation compliance.

between methane and oxygen, the
gas mixture can be explosive. Even
if such critical gas compositions
occur extremely rarely, the
Set BGA is designed with a
high safety standard to ensure
operational safety and explosion
The Set BGA consists of the
following units:
• ULTRAMAT 23 analyser with
four measured gas components
