USGS Circular 735: Guidelines on Collecting Coal Samples

The objective should be to obtain a complete channel sample or core of the minable bed; if the coal bed is more than 5 feet (1.5 m) thick, a good rule-of-thumb is to collect one sample of each 5-foot (1.5-m) interval of coal (for example, four

Cement mill

By adjusting the fineness of grind, the manufacture can produce a range of products from a single clinker. Tight control of fineness is necessary in order to obtain cement with the desired consistent day-to-day performance, so round-the-clock measurements are made on the cement as it is produced, and mill feed-rates and separator settings are adjusted to maintain constant

Memories of a Coal Child

I have a rule of thumb that I have followed for sixty years: any Polish Jew's account of his or her experiences during World War II must be taken with a grain of salt. So it is, for example, that the posthumous unraveling of the fraud that was Jerzy Kosinski's autobiography only confirmed what I had already suspected.

Guide To Clean And Efficient Operation Of Coal

Coal Fines The common definition of coal fines is the percentage of coal which passes through a 1/4 screen. Too many coal fines can lead to high particulate loadings because they are easily carried out of the furnace, and high combustible heat losses because the particulate matter carries carbon out of the furnace with it.

Area Required for Solar PV Power Plants

A simple rule of thumb is to take 100 sqft for every 1kW of solar panels. Extrapolating this, a 1 MW solar PV power plant should require about 100000 sqft (about 2.5 acres, or 1 hectare). However, owing to the fact that large ground mounted solar PV farms require space for other accessories, the total land required for a 1 MW of solar PV power plant will be about 4 acres.

In PJM, the general rule of thumb is that CCGTs run baseload while OCGTs and coal plants run mid-merit. Emissions have fallen precisely because coal has move towards the back of the merit order. The 2008-to-2018 comparison illustrates the rationale behind the dramatic 'fuel switch' that has occurred over the past decade.

Coal drying Grinding. Coal Mill

Earlier the rule of thumb was in use — to grind coal to a fineness (+90 ) not less than half of its volatiles content as in earlier days a part or full calcination was carried out in the kiln. Surprisingly, same concept is still applied in few occasions for ILC/SLC kiln where only 3–4 seconds is available for coal to react.
