Soft‐sensor approach for measuring pulverised coal flow

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 soft-sensor, and for that an accurate and computationally efﬁcient coal mill model is required. Bollinger and Snowden [1] proposed a transfer function model of the coal mill ...

Mechanochemical stabilization of heavy metals in fly ash ...

Fly ash from coal-fired power plants was treated by the dry milling and wet milling method. The technical feasibility of stabilizing typical heavy metals, including Pb, Cr, Cd, Ni, Cu, and Zn because of their severe toxicity and then enriching them to enriched in different degrees in fly ash during coal combustion ( Zhang et al., 2002 ) was studied.
