Comparative study on the particle emission characteristics ...

Biomass boilers were widely used as an effective method for biomass combustion. However there were not many studies on the characteristics of atmospheric pollutants emitted from biomass boilers. Two biomass boilers with different structure were selected to study the emission characteristics of dust PM10 and PM2.5 and compare it with coal-fired boiler.

Wood Smoke Particle Sequesters Cell Iron to Impact a ...

The biological effect of an inorganic particle (i.e. silica) can be associated with a disruption in cell iron homeostasis. Organic compounds included in particles originating from combustion processes can also complex sources of host cell iron to disrupt metal homeostasis. We tested the postulate that (1) wood smoke particle (WSP) sequesters host cell iron resulting in a disruption of metal ...

How Filters Work - Gas Mask Filters | HowStuffWorks

Sep 28 2001 · Most biological particulate filters remove particle sizes as small as 0.3 microns. Any particulate filter eventually clogs so you have to replace it as breathing becomes difficult. A chemical threat needs a different approach because chemicals come as mists or vapors that are largely immune to particulate filtration.
