Introduction to Cyclones
underflow. Obviously, a very large particle has a very small possibility of reporting to the overflow, but it does have a possibility, even if it is very low. Since the feed stream contains millions of individual particles, if there is a possibility of a million to one, then one particle in a million (of that size) will "go the wrong way".

Pore size measurement :: Anton Paar Wiki
When considering pore size, a set of standards approved by IUPAC has defined pore size ranges based on different size widths. Pores with an internal width of less than 2 nm are referred to as micropores, those with an internal width between 2 nm and 50 nm as mesopores, and those larger than 50 nm are called macropores (See Figures 2 and 3).

Fly ash
Fly ash material solidifies while suspended in the exhaust gases and is collected by electrostatic precipitators or filter bags. Since the particles solidify rapidly while suspended in the exhaust gases, fly ash particles are generally spherical in shape and range in size from µm to 300 µm. The major consequence of the rapid cooling is that few minerals have time to crystallize, .

Ammonium sulfate
Ammonium sulfate has been produced for more than 150 years. Initially, it was made from ammonia released during manufacturing coal gas (used to illuminate cities) or from coal coke used to produce steel. Today, manufacturers make it by reacting sulfuric acid with heated ammonia (see process schemes below).

· The PM10 tax makes a bigger reduction in these emissions than the coal tax. Calculations show that even with a value per ton of CO2 of just 10, the reduction in CO2 for the 10% PM10 reduction case is worth 59 billion, little more than the loss of GDP. For the 30% case, the reduction is worth 83 billion, slightly less than the loss of GDP.
