pulverized coal at the mill outlet is 30%, the gas temperature required at the mill inlet is considered to be approximately 450°C. The evaporation of water in raw coal increases the vapor concentration in the gas at the mill outlet and consequently the O2 level of the primary gas in the burner is expected to be decreased to approximately 9%.

It is preferable to measure the air velocity entering the mill inlet using a simple hand-held anemometer. This will indicate the actual air flowing into the mill and will discount the impact of false air. Some allowance does need to be made for any additional air that may enter either with the raw materials or back from the re-circulating load.
