Isokinetic Sampling Method Using a Probe: Overview

Isokinetic sampling is widely used in dust and particle measurements in power plants, furnaces, kilns, and scrubbers. Ambient air pollution measurements also make use of this method. Other applications in coal-fired power plants include sampling of pulverized coal and sampling steam to check the purity before in enters the turbine.

Pulveriser in Thermal Power Plant | Bowl Mill | Ball Mill

Introduction. The main Function of the Pulveriser in thermal power plant is to crush/grinding the raw coal coming from coal handling system through coal feeder into a pre-determined size in order to increase the surface area of the coal.. If the coal is not pulverised, the coal might not burn completely, thus resulting in wastage of fuel.
