Measurement and characterization of fine and ultrafine particles in emissions from CHP Plants in Denmark
CHP (Combined Heat and Power) Plants are being increasingly used due to their ability to utilize the heat generated from energy production. The type and magnitude of air emissions from CHP plants vary widely according to the energy source used and technology implemented for combustion and emission reduction. In 2008-2009, emissions of gaseous and particulate components have been measured from a 9 different CHP Plants in Denmark. Ultrafine and fine particles has been measured from CHP Plants (< 25 MW) powered by waste, biomass and natural gas.
This presentation will give an overview of the method used and results obtained from
- Measurements of the number and size distribution of particles (from 7 nm – 2,500 nm) from 9 Danish CHPPlants. Measurements were performed by means of ELPI (Electrical Low Pressure Impactor).
- Calculation of mass emissions of PM0.1, PM1 and PM2.5 from number measurements.
- Analysis of morphology and possible origin of particles by SEM (Scanning Electron Microscopy) and FIB(Focused Ion Beam) analysis (from 30nm and upwards).
An assessment of the type and magnitude of particulate emissions from the different CHP Plant types will be given,including the effect of the emission reduction systems involved.
