Specifically, Isokinetic testing has been at the center of two recent legal rulings regarding employer physical abilities testing. In the first case, the EEOC charges that CSX Railroad''s testing, administered by IPCS, had a disparate impact on candidates .
The expected injury costs for the Tested group was 461,214 and the observed cost was 18,018 or a difference of 443,196, which yields a 2,460 percent reduction. The expected injury cost for the Not Tested group was 392,886 and the Observed was 364,416 or a difference of 28,470, which is an 8 percent reduction.
vii. Repeat the same procedure for completing the isokinetic coal sampling from the remaining coal transport pipes of the same mill. A new filter needs to be used for testing of each coal pipe. viii. After completing the testing of all the coal transport pipes of a mill, calculations can be done as per the following formulae.

Each coal sampling kit we sell comes with everything you need to draw a proper isokinetic sample from a fuel line and conduct a comprehensive pulverizer test for optimum performance. With this kit, you will be able to perform clean air tests on each pulverizer as well as determine the static pressure and temperature, dirty air velocity, and ...
Isokinetic sampling therefore required utilizing an internationally recognized validated method ... plants as compactly and cost effectively as possible ... typical of a large industrial coal fired boiler power plant
A multipoint sampler extracts one representative sample from 64 sampling points evenly distributed over the crosssection of a circular pipe. The sampling gas velocity is maintained at the same level as the gas velocity in the transport pipe all through the sampling period, to ensure an isokinetic sampling.
Our Isokinetic equipment is designed to be modular, where you choose your meter console, pump and components of choice to meet your particular needs. The Apex Method 5 Sampler System provides a reliable and versatile foundation for performing most isokinetic testing methods. Typical Industries Tested by Apex Isokinetic Equipment: Acid Plants
Coal Centre – Coal sampling and analysis standards 4 Abstract Each year, billions of tonnes of coal are traded in regional and international market for use in power generation, steel and cement making, and many other purposes. In commercial operations, the price of coal
Where is Isokinetic Sampling used? Isokinetic sampling is widely used in dust and particle measurements in power plants, furnaces, kilns, and scrubbers. Ambient air pollution measurements also make use of this method. Other applications in coalfired power plants include sampling of pulverized coal and sampling steam to check the purity before ...
Pulverized Coal Flow Measurement According to ASME PTC The ASME PTC Coal Sampling System is utilized to sample particulate carried within an air stream. The sample is extracted isokinetically to determine the particulate flow rate. The sampling probe features a single, slotted nozzle meeting the geometry specifications of the ASME method.

Feb 12, 2012· Isokinetic Stack Sampling Probe and its terrain are delicate precision instrumentation. Handling this equipment with lots of TLC (TenderLove Care) would ensure its durability and worthy glass nozzle could withstand high temperatures of most stacks but vulnerable to the slightest knock on hard surfaces.
Any mine needs to weigh up the costs versus the benefits of isokinetic sampling. Very often the benefit side of the scale is a bit on the light side. The main difficulty with isokinetic sampling is to try and make the sample as representative as possible of the dust in the stack or duct, without excessive costs. The arguments are that the ...
These companies often report emissions that are much lower than the actual emissions. This misleads Air Quality Officers. An example of this is a boiler stack in Boksburg where 3 737 mg/Nm 3 of PM was measured when proper isokinetic testing was performed. This was expected as a coal fired boiler that is not equipped with any abatement equipment typically emits ± 3 000 mg/Nm 3 of PM according ...
Isokinetic Sample Probes Isokinetic Sample Probes are designed to extract a sample from the stack with the velocity of the air entering the nozzle flowing at the same velocity as the free gas stream in the stack. With the two velocities being equal this ensures that there is no over or under sampling of the particulate in the gas stream.
Administrator. A range of nozzle sizes suitable for isokinetic sampling should be available. Typical nozzle sizes range from to cm (1⁄ 8 to 1⁄ 2 in) inside diameter (ID) in increments of cm (1⁄ 16 in). Larger nozzles sizes are also available if higher volume sampling trains are used.
