Particle characterisation and particle emissions

•

Sprays and nozzles (LDA/PDA)

In energy engineering applications, it is important to characterize particle and droplet morphology. The emission of particle matter from a furnace needs to be recorded for different operation and fuel parameters so that the impact of the combustion process inside the furnace can be assessed. In many combustion and gasification processes, different forms of spray system occur frequently. The size distribution of the droplet in the spray often determines the efficient of the process.

ETC has very advanced instruments for particle and droplet characterization. The particles' mass size distribution can be analysed with a low pressure impactor that size separates particles according to their aerodynamic diameter in 13 stages from 0.03-10.7 microns. The particle concentration in the flue gas can also be analysed with an absolute filter.

Droplets and sprays are analysed with a very advanced laser method, PDA (Phase Doppler Anemometry). The velocity and the diameter of the droplets are measured with high accuracy. The system can also be used for measurements of the velocity for solid particles in suspension with air or water.
