  • Soft‐sensor approach for measuring pulverised coal flow

    coal flow from the coal mill is essential. Direct measurement of the pulverised coal flow from a coal mill using a physical sensor is very costly. An alternative way to obtain a pulverised coal flow rate is to design a softsensor, and for that an accurate and computationally efficient coal mill model is required. Bollinger and Snowden [1]
