Gravimetric analysis - Wikipedia

Gravimetric analysis describes a set of methods used in analytical chemistry for the quantitative determination of an analyte (the ion being analyzed) based on its mass. The principle behind this type of analysis is that once an ion's mass has been determined as a unique compound, that known measurement can then be used to determine the same analyte's mass in a mixture, as long as the .

how load cell works in gravimetric coal feeder

Pfister High-end gravimetric weighing, dosing and . What is special about Pfister rotor weighfeeders for coal power plants? Pfister rotor weighfeeders work like horizontal star feeders. The gravimetric mass in the feeder is measured by a load cell. The speed of the feeder motor is controlled inverse to the mass content in the feeder.

Air–fuel ratio - Wikipedia

Air–fuel ratio (AFR) is the mass ratio of air to a solid, liquid, or gaseous fuel present in a combustion process. The combustion may take place in a controlled manner such as in an internal combustion engine or industrial furnace, or may result in an explosion (e.g., a dust explosion, gas or vapour explosion or in a thermobaric weapon).. The air-fuel ratio determines whether a mixture is ...
