Collecting coal samples using an isokinetic probe provides the best data describing actual operating conditions inside the coal pipe. Source: Storm Technologies Inc. The isokinetic coal sampling method, although more difficult, is the best option for determining the true mill coal fineness produced and to calculate pulverizer performance.
These factors are usually expressed as the weight of pollutant divided by a unit weight, volume, distance, or duration of the activity emitting the pollutant (e. g., kilograms of particulate emitted per megagram of coal burned). Such factors facilitate estimation of emissions from various sources of air pollution.

Selection of the furnace exit temperature, T f,exit, is governed by many factors. The major ones are. 1. type of coal (and therefore the ash characteristics) – commonly using the ash fusion temperature, 2. burner type and arrangement, 3. coal firing rate (which is in turned determined by the unit capacity and load factor).
A pugmill or pug mill is a machine in which clay or other materials are mixed into a plastic state or a similar machine for the trituration of ore. Industrial applications are found in pottery, bricks, cement and some parts of the concrete and asphalt mixing processes. A pugmill may be a fast continuous mixer. A continuous pugmill can achieve a thoroughly mixed, homogeneous mixture in a few ...
