Mar 13, 2015· These 2-part coal feeding systems were expensive, complicated, and became a huge headache for electric power stations. Sometimes, for instance, they got plugged up and coal stopped flowing freely. In the 1950s, Arthur Stock combined accurate weighing and coal-flow control systems into a single device, which was named the gravimetric feeder.

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 .
