Temperature Measurement and Control for Cement

2021-11-23  The burning zone is the last stage before the material exits the kiln. A single burner fires toward the approaching material, and precise temperature measurement is important to control the firing of the burner. A PSC 2-color pyrometer is effective for monitoring the burner zone as they compensate for dust that can obscure the sight path.
