Feb 01, 2015 Operators have not observed a change in corrosion with the use of higher-chlorine coal, including the results of a 90-day test using 90 higher-chlorine coal.
Coal and the high temperature inside the mill lead to rapid oxidation of the coal. This results in further heat build-up and the potential for a fire. If the mill is restarted without first removing the hot coal, an explosion can occur when particles are suspended and exposed to the in-rushing combustion air.
Jul 05, 2009 Pulverized coal fired boilers the total losses account to about 12 to 14 . Roughly 50 of the losses can be tuned to the optimum and the other 50 is governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The main two losses in boiler that can be tuned by operator are carbon loss and dry gas loss.
