Measure your primary air drift free and accurate all the time with advanced air flow technology

Precision measurement and control: The digital air flow technology will always provide you a 100% drift free and accurate air flow measurement through your mills. 

Better mill control: you will have a better handle on mill filling levels, mill grinding condition as well as mill dynamics with a digital and accurate control of your Primary Air Flow.

Better fuel flow control: you will have a better control over the transport velocities, moisture and particle size of your pulverized coal. The PA flow is one of the most essential air flow measurement points in a milling process.

Enhance the crucial parameter of primary air in your milling process with reliable primary air flow monitoring

1. Optimize your boiler efficiency: The exact long term Primary Air Flow control through all pulverizers of your plant will ensure a more steady and flat-lined combustion throughout all burner levels. Hence excess air levels can be reduced using accurate air flow measurement.

2. Less mill downtime: Mill trips due to unsteady air flow measurement will be a thing of the past. Have a higher reliability of your mill through stable primary air flow control. Also reduce wear on your tires due to a better bed depth control of the coal.

3. Better NOx and UBC control: reduce your primary pollution by NOx as well as CO and UBC by a better fineness control through correct Primary Air Flow settings enabled by digital air flow technology.

Increase load flexibility, lower NOx and particle size of your combustion with optimized Primary Air Flow

Larger fuel variability: changing fuels can save massive costs for a plant. However the mills need to be capable of dealing with different fuel types. The accurate settings of crucial mill parameters such as Primary Air Flow substantially helps with this using precise air flow measurement.

Better load swing capacity: renewable energy demands higher load swings of coal fired power stations. For any rapid change in load mill control and hence Primary Air Flow control to the mill is absolutely essential. The coal charge and discharge function of a mill is dependent upon correct air flow measurement and PA settings to the mill.

Lower maintenance on your PA flows: the digital PA measurement of PROMECON based on advanced air flow technology drastically reduces maintenance requirements. There is no need for cleaning or purging of the flow meters. Also, any recalibration of zero or span is not necessary as the digital system is measuring air velocity directly and hence will keep its calibration over it´s life time, ensuring stable air flow measurement.

Key features:

1. Digital air flow technology: no need for recalibration, zero and span adjustment

2. No maintenance: there is no regular cleaning nor any recalibration necessary on this air flow measurement technology. Hence the measurement offers a high reliability in service when used on coal pulverizers.

3. Easy installation on existing pulverizers: find the location of your old air flow measurement. McON air will fit in easily, using existing venturis or airfloils while upgrading to modern primary air flow measurement. Use the advantage of the easy installation of a digital flow meter. No impulse lines no plumbing.

Rely on PROMECON – Your partner for excellent measurement technology and process optimization in the cement industry.

Monitor your fly ash quality online

Representative measurement of UBC: McON UBC allows the online measurement of the fly ash carbon content directly in the bulk fly ash on the EP outlet, providingaccurate unburned carbon visibility.

Low maintenance solution for your plant: the McON UBC system has the lowest maintenance requirement of UBC analyzers. It works non extractive and hence has no problems with ash congestion or blocking of parts, supporting stable monitoring of fly ash carbon content..

Monitor your LOI: the UBC measurement also allows to monitor the LOI for environmental compliance and the resale of the fly ash based on controlled unburned carbon levels.

Optimize your plant cost

Maximize fuel use: The unburned carbon content is directly proportional to the fuel loss of the boiler.  Monitoring this parameter will help to increase the efficiency of your plant and reduce fly ah disposal requirements.

Minimize your ash disposal cost: Making best use of the fly ash will minimize your cost for fly ash disposal. Fly ash quality defined by fly ash carbon content is a key parameter of competitiveness of a coal fired plant.

Minimize your maintenance: The low maintenance requirement of the UBC system keeps down your maintenance cost for the UBC instrumentation while reducing the need for lab analysis. So, the cost of unburned carbon monitoring comes down.

Key Features:

1. Instant UBC analysis: get a new value for unburned carbon every few minutes.

2. Representative measurement: ensuring reliable fly ash carbon content monitoring  The measurement of McON UBC happens in the bulk fly ash and not with a tiny sample from the flue gas duct.

3. Unique patented solution: McON UBC is based on PROMEOCN´s patented measurement technology which is measuring unburned carbon on a compacted bulk fly ash sample online, supporting optimized fly ash disposal strategies.

Digital online flue gas flow measurement is here, providing continuous visibility into real-time process conditions

Dealing with large ducts: McON air is designed as vector measurement, supporting reliable airflow measurement in complex duct geometries. This enables the measurement of extremely large cross sectional areas by a multipoint measurement, improving airflow optimization across the system. Measure ducts right out of your Air Heater or into your ID Fan or scrubber for precise flue gas flow measurement.

Dealing with dust: no matter how dusty your flue gas may be, McON air uses the dust as a tracer for a high accuracy digital measurement, ensuring stable airflow measurement even in harsh environments.

Go Digital, go multipoint: the no maintenance requirements of the McON air system make it ideal for use on large duct works, where multiple flue gas flow measurement points are required. Rely on total airflow measurement for years without the need for maintenance nor recalibration, enabling long-term airflow optimization.

Savings potential by optimized flue gas flow

Save electric power: correcting gas flow distribution and balance on the ID fan level through accurate flue gas flow measurement will result in significant electric power savings, directly supporting airflow optimization strategies. 

Reduce your ingress air losses: measuring accurate gas flows using advanced airflow measurementtechniques results in reduced flue gas flow demand on the ID fans.

Detect maintenance problems with your air heaters: Flue gas flow measurement downstream of the air heaters reveals imbalances between the A- and B-side air heater, allowing targeted maintenance and improved airflow optimization with substantial savings potential.

Key features:

Digital measurement: totally drift-free, no maintenance, allowing multiple airflow measurement points in hot and dusty flows online over years.

Vector measurement: measure large ducts independent from swirl and other lateral air velocities. Since honeycomb flow straighteners can`t be fitted into bulk gas ducts, vector-based flue gas flow measurement is the only reliable option for accurate airlfow optimization.

High Temperature: Measure hot gas up to 800°C with reliable airflow measurement. Usual restrictions of dP measurements, ultrasonic or hotwire anemometers at high gas temperatures do not apply to McON air digital flue gas flow measurement technology.
