Effect of the Fineness of Pulverized Coal on the

On the understanding that the characteristics of the gas flow have a major contribution to slagging, a change in the fineness of pulverized coal necessitates taking into account the change in the properties of fly ash, which can either improve or worsen the slagging situation.

Coal Flow Measurement, Balancing, and Boiler

2014-5-28·Coal Flow Measurement, Balancing, and Boiler Optimization. One of the most significant causes of carbon-in-ash (LOI or un-burnt coal) and Nitrous Oxide emissions (NOx) into the atmosphere is the imbalance and delivery of the pulverised fuel (PF) delivered to the boiler through the burners particularly on a front (and rear) walled boilers.
