WHAT IS PARTICULATE MATTER (PM)

A Mixture of solid particles and liquid droplets found in the air.

Some particles like dust, dirt, soot or smoke can be seen by a naked eye.

Some are so small, that they can only be detected by an electron microscope.

PM 10 : Inhalable particles smaller than 10 microns in diameter.

PM 2.5 : Inhalable fine particles smaller than 2.5 microns in size.

To imagine the size, our human hair at 70 microns is 30 times larger

than a particle of diameter 2.5 microns!

15

HEALTH AND ENVIRONMENT EFFECTS

Particle size is directly linked to the health hazard potential.

Particles smaller than 10 microns cause the biggest problems.

They can get deep into your lungs, and even in your bloodstream!This could affect your lungs and heart leading to problems like:

Premature death for people with heart or lung disease.Non fatal heart attacksIrregular heart beat

Aggravated asthmaDecreased lung functionIrritation of the airways, coughing, difficulty in breathingChildren,Old adults, people with lung,heart problems arethe most affected.

16

SOURCES OF PARTICULATE MATTER

Particles come in many sizes and shapes and made up ofhundreds of different chemicals.

Some are emitted directly from a source, such as Construction sites, unpaved roads, fields, smoke stacks or fires

Most particles form in the atmosphere as a result of complexReactions of chemicals such as sulfur dioxide, nitrogen oxidesEmitted from Power plants, industries and automobiles

CFD FOR ESP

The uniform and streamline gas flow within ESP is the major factor that Governs the ESP performance. We do Flow simulation of gas to ensure desired flow is achieved, the performance.
