Therefore, our study presents the optimization of particles size of pulverized coal in 650 t/h pulverized coal fired boiler with natural circulation (type OP 650) to the power unit 225 MW that is equipped with ballring mills. This boiler is marked in the power plant as K6.
(pulverized fuel), and the distribution calculated by comparing sensors from each mill. Velocity is calculated as the time of flight between 2 of the sensor rings using crosscorrelation. Having a spool piece allows the measurement to be integrated around the whole circumference so that the effect of variable coal location in the pipe is overcome.
