Reduce Unburned Carbon to a minimum

Online monitoring of unburned carbon helps to maximize environmental compliance and fuel efficiency

Produkt

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.

Enhance the environmental compliance of your plant

Lower your environmental footprint: The online monitoring of unburned carbon will allow you to use the UBC as target parameter in order to lower your excess air settings.  This will increase plant efficiency, lower heat rate as well as particulate emissions while improving fly ash carbon content control.

Maximize your ash sales: by online monitoring of fly ash carbon content, the ash can be sorted and the yield of sellable fly ash can be maximized.  Hence the fly ash disposal volumes can be minimized.

Optimize your plant´s coal diet: The monitoring of unburned carbon will also allow to adopt to different types of coal with varying volatile content and reactivities. The UBC measurement can be used to find adapted combustion settings while maintaining acceptable fly ash carbon content.

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:

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

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.

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.
