coal level measurement of and tube mills in power plant

Level measurement and point level detection in the coal surge bin In a typical coal power plant, lignite (soft coal) and anthracite (hard coal) are stored temporarily in bins up to 30 meters high. To ensure that the coal belts are continuously loaded without interruption, a robust and reliable level measuring system is required.

The mill-duct systems of a real Power Plant are very complex and they are not yet well understood. In particular, experimental data concerning the mass flows of coal to the different levels are very difficult to measure. CFD modeling can help to determine them. An Eulerian/Lagrangian approach is used due to the low solid–gas volume ratio.

Level measurement in water treatment Complex water treatment systems are installed to supply the power plant not only with high-quality demineralized water, but also with service water for cleaning or for fire fighting in emergency cases.
