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.
