Ultrafine and Respirable Particles in an Automotive Grey …

Particle sources were further characterized by measuring their respective number and mass concentrations by particle size. Sources that contributed to ultrafine particles included process-specific sources (e.g. melting and pouring operations), and non-process sources (e.g. direct fire natural gas heating units, a liquid propane-fuelled sweeper and cigarette smoking) were additionally identified.

Grinding elements maximise pulveriser operating | …

Vertical Mill design also plays a factor; namely the orientation or position of the grinding elements relative to the throat vanes and the pulverised coal and primary air (PA) velocity vectors. The table is generally positioned at or below the centreline of the PA throat vanes thus the primary wear mechanism on the table is from compression and the sliding friction of the coal across the table.

Briquetting Process

Fluidised bed combustion of brown coal, on the other hand, subjects coal particles to a very high rate of particle-to-particle heat transfer when they enter a hot bed of fine, fluidised material. Fluidised combustors can therefore accept granulated rather than pulverised coal particles and they allow the drying process to be carried out in the bed.

The light/dark cycle can be manipulated by using artificial light sources to increase microalgae growth. In general, biomass productivity increases with increasing photoperiod. However, the light intensity and photoperiod affect the growth interactively; high light intensity together with a long photoperiod causes a decrease in microalgae growth or even cell death [ 80 ].
