Furnaces, heaters, and boilers burn fuel in the presence of oxygen to produce heat. Achieving an intelligent balance of fuel and air will provide the most efficient combustion and highest cost savings.

Measuring the exhaust gas is an excellent way to optimize fuel and air input. Nova manufactures continuous and portable analyzers for this purpose. A flue gas analyzer will enable you to measure the concentrations of various gases and adjust burners on a boiler to help achieve optimal combustion.
Efficient combustion also reduces emission of pollutants such as nitric oxide (NO), nitrogen dioxide (NO2), sulfur dioxide (SO2), and particulate matter. A gas analyzer will help measure various gas pollutants in the exhaust for environmental reasons. One term that frequently arises in this application is ‘CEMS’.
Flue Gas Analyzer for O2, CO & CO2 - Model 375WP: The Nova 375 Series Portable Flue Gas Analyzers have been designed for accuracy, reliability, ease of use and ease of service, providing a detailed analysis of flue gas composition. Nova uses a reliable high volume pump to quickly pull the sample into the analyzer. Most of our multi gas analyzers will be 20-30 seconds to 90% step change. Can your analyzer go outdoors? In hot or cold weather? Many multi-gas applications are located indoors. However, Nova continuous analyzers are built into sturdy weather-proof enclosures.

CEM Systems
CEMS is an acronym for Continuous Emissions Monitoring System. This term can technically apply to any instrument that is measuring some of the various constituents of an exhaust gas on a continuous basis. However, the generally accepted use of ‘CEMS’ refers to an analyzer system that conforms to the methodologies and design features as outlined by a government environmental department such as the Environmental Protection Agency in the USA. Acceptable methods for sample conditioning, gas measurement, reporting of results, and other functions are established by the governing body and the resulting data will be accepted in emissions reports made to the government by the user.
In many countries, industrial facilities are required to report their emissions of various exhaust gases that are considered ‘criteria pollutants’. CEMS equipment can provide continuous analysis of many of these gases and can be used to report emissions. Particulate matter measurements may also be grouped in with CEMS requirements. While not a gas itself, particulate matter does have environmental and health effects when it is small enough to be suspended in the atmosphere.
CEMS equipment usually tends to be quite expensive and may be an unsustainable cost for a facility. To satisfy the reporting requirements while minimizing equipment costs, some facilities install a lower-cost non-compliant analysis system at their emissions point. The analysis system is non-compliant in the sense that alternate conditioning and measurement methodologies not accepted by the governing agency are used in the gas analyzer. Once a year, the facility obtains the services of a mobile CEMS company to measure the emissions using compliant equipment. The results are compared, and the relative accuracy of the installed non-compliant analyzer system is determined.

NOVA Capabilities
Nova has capability in the non-compliant CEMS category. Nova systems are accurate and durable, but they use some methodologies which may not be approved by some governmental agencies. These systems will require a Relative Accuracy Test Audit once a year to evaluate the reporting accuracy of the analyzer.
The NOVA 7200 Flue Gas Analyzer System uses the following measurement technologies:
- Oxygen by electrochemical sensor, range 0-25.0%
- Carbon Monoxide by electrochemical sensor, range 0-1,000 PPM
- Carbon Monoxide by infrared detector, range 0-2,000 PPM to 0-10.0%
- Carbon Dioxide by infrared detector, range 0-20.0%
- Nitric Oxide by electrochemical sensor, range 0-2,000 PPM
- Nitrogen Dioxide by electrochemical sensor, range 0-800 PPM
- Nitrogen Dioxide Calculation, based on Nitric Oxide measurement
- Sulfur Dioxide by infrared detector, range 0-2,000 PPM
- Stack Temperature by TypeK thermocouple, range 32F – 1800F or 0C – 1000C
Combinations of the above gas measurement options are usually also purchased with oxygen measurement. This allows the user to ‘normalize’ the other gas readings to oxygen. That is, they allow the other gas readings to be corrected by the customer to a reference oxygen content.

Our continuous flue gas analyzers are sturdy and weather-proof. They are able to function in temperatures from -22 F to over 100 F with the appropriate weather package options. They can also be modified with extra filtration devices for improved sample quality.
Nova analyzers use reliable high volume pumps for quick analysis times. In our stack gas analyzers, the detectors and sensors can reach 90% of reading in less than 20-30 seconds in most cases. (Sample line lengths will add to response time.)

Portable Flue Gas Analyzer Models
Nova has produced portable flue gas analyzers for more than 35 years. Technicians and facilities choose Nova Systems because they’re versatile, intuitive and easy-to-use, and durable.
Flue gas analysis using a Nova flue gas analyzer will enable you to measure the concentrations of pollutants present and adjust burners on a boiler for optimal combustion. Nova exhaust gas analyzers are useful for environmental control, for general boiler maintenance, and also as a tool for reducing fuel costs.
Nova’s portable flue gas analyzers are:
- Portable thermo-electric style pre-cooler
- Portable ice-bath style pre-cooler

Continuous gas analyzers comprise a significant portion of the Nova Analytical product line. These types of instruments are generally used for continuous gas analysis of an individual sample point in a facility.
Because these analyzers are intended for permanent exposure to the sample gas, they must be equipped with suitable sample conditioning components. This means that continuous analyzers are bigger than portable analyzers, and they are almost always permanently mounted to a wall or other vertical surface.
Cabinet Styles
Nova Gas Analyzer 375wp User Manual 2017
a) NEMA 4 (N4) – This is our most popular style of cabinet. It is very strong and is made of powder-coated steel. This is a vertical-mount cabinet that is considered to be weather-proof. The cabinet door has a window and a tight-fitting seal that ensures cabinet integrity against ingress of dust or moisture. A panel behind the door window contains the display(s), controls, fuse(s), and any other relevant components. The interior panel can swing out to allow access to the internal components.
b) NEMA 4X (N4X) – This cabinet is very similar to the N4 cabinet except that the materials of construction make it stronger and more corrosion-proof. In most product lines, we offer a stainless steel N4X option. Projects located in industrial settings generally utilize this cabinet. In some product lines, we offer a reinforced fibreglass N4X option.
c) NEMA 12 Dust-tight fibreglass (N12) – This cabinet is only offered in our air quality monitor product lines. The door opens to allow access to the internal components. The door contains the displays and alarm lights. This cabinet is also frequently offered with audible and visual alerts. (If air quality monitoring is required on an industrial site, we substitute the NEMA 12 cabinet for the NEMA 4 or 4X.)
d) Rack mount (RM) – The rack mount cabinet is offered on only a few of our products intended for the process applications. The internal shape and dimensions of the cabinet limit the type and amount of sample conditioning components.
e) Explosion Proof (N7MC) – Some applications require that the analyzer have an explosion-proof cabinet. Due to size constraints of the ex-proof cabinets we use, these analyzers are usually suitable for analysis of only one gas in a sample that is clean and dry. Here is some more information on the analyzer options for hazardous areas.
Particulate Filtration
For some continuous applications that have particulate or soot in the sample gas, it is important to filter the gas at the extraction point. The Nova Model 7240 provides this function. It mounts at the stack or duct and is usually controlled by the analyzer. The filter system uses a blast (or ‘blow-back’) of nitrogen or compressed air to periodically clear the filter element and the probe. The frequency and duration of the blowback can be easily programmed by the user. The basic configuration of the system looks like this:
