Seventy grams of each pulverized coal sample is oxidized at 525° C for 36 h to determine the percent ash and to provide ash required for chemical and instrumental analyses. INTRODUCTION All procedures described in subsequent sections of this bulletin on the chemical and instrumental analysis of coals depend upon the comminution step.
The measures involved were made by using an equipment of manual isokinetic sampling, owned by the Power Plant of As Pontes, for measures of dynamic and static pressures in ducts, temperature and mass flows of pulverized coal. This sampling equipment is designed for use together with a zero pressure probe, which allows the imposition of isokinetic conditions during the extraction of the coal samples.
Reducing the pulverized coal particle size (in particular, eliminating the coarse particles) increases the surface area to volume or mass ratio, effectively making the coal more reactive.
A piezoelectric vibratory feeder produced continuous flow of pulverized coal particles, which were detected by laserinduced breakdown spectroscopy (LIBS), and corresponding spectral information ...

boiler operation, pollution control equipment, and coal properties. Uncontrolled PM emissions from coalfired boilers include the ash from combustion of the fuel as well as unburned carbon resulting from incomplete combustion. In pulverized coal systems, combustion is almost complete; thus, the emitted PM is primarily composed of inorganic ash residues.
SAMPLING LOCATIONS coal used was: Moisture, %; Ash, %; Volatile, % and Fixed Carbon, %. To meet the testing objectives three coal size tests were needed. Test I burned a typical pulverized coal with 60% passing a 325 mesh screen and an average par ticle size of 33 microns (8% > .

This time, however, is dependent on various factors. The heart of a pulverized coalfired boiler is the pulverizer, also known as the mill. Depending on speed pulverizers are classified as lowspeed, mediumspeed, and highspeed mills. Pulverized coal burners may be located on the front or opposed walls or in the corners of the furnace.
Isokinetic sampling can be defined as sampling at such a rate that the velocity and the direction of the gas entering the sampling nozzle is the same as that of the gas in the pipe/duct/stack at the same sampling point [17].
