BALANCING OF PULVERIZED COAL FLOWS TO BURNERS …

The issue of poor coal distribution is a common problem in vertical spindle mills, adversely effecting unit performance and efficiency. Any deviation from the specified air-to-fuel ratio in a coal pipe results in a fuel rich or fuel lean zone in the vicinity of a particular burner. In particular, CO emissions and unburned carbon in fly ash ...

Coal Mill

A simple energy balance model of the coal mill is derived in (Odgaard and Mataji 2006), this model is based on a more detailed model found in (Rees and Fan 2003).In this model the coal mill is seen as one body with the mass m m.The following variables are defined: T(t) is the temperature in the coal dust flow in the mill, ṁ PA (t) is the primary air mass …
