How to select the economic fineness of pulverized coal?

13 Mar 2020

The fineness of pulverized coal is an important indicator to measure the pulverized coal quality.

In terms of combustion, the fineness of pulverized coal is expected to be as small as possible to facilitate the ignition and combustion, reduce the heat loss of incomplete combustion, the amount of air supply and heat loss of exhaust smoke.

In terms of pulverized coal milling, the fineness of pulverized coal is expected to be as coarse as possible to reduce the power consumption and steel consumption. Therefore, when selecting the fineness of pulverized coal, a compromise of the two aspects is taken as the economic fineness.

It shall be determined through combustion adjustment tests according to the fuel properties and the type of pulverizing equipment.
