This study presents a soft sensing model of coal moisture for utility boilers. The model is based on the energy and mass balance of matter in the inlet and outlet of a positive-pressure, direct-firing, MPS-type mill. Compared with the results obtained with a proximate analysis method, the results calculated with the soft sensing method are consistent with proximate analysis data.

On the contrary, the inlet primary air flow and the outlet temperature of coal mill are gradually increased. Therefore, the openings of the cold and hot regulating values do not change. As the coal feed flow gradually rises after 200 s, the mixed air regulating value continues to close, the primary air flow and pressure decrease rapidly, and the outlet temperature …

Based on the energy and mass balance of the inlet and outlet of a positive-pressure, direct-fired, MPS-type medium-speed mill, a quadratic equation of coal moisture is derived. The solution to the quadratic equation is discussed in detail, and a simple solution method for the online soft sensing of coal moisture is given.
Coal Moisture: The degree of drying, and therefore the required mill outlet temperature (from 65-80 0 C) will depend upon the type of coal ground. Some residual moisture in fine coal is recommended (Graph below) to minimize the potential of spontaneous ignition of fine coal, which will again vary for different coal types as below:
We have inlet and outlet temperatures coal plant,Coal mill hot air inlet temperatures should never be more than 600 f and the outlet temperature should not exceed 200f on raymond coal mills if the flow of raw coal to the coal mill is interrupted for any reason for example plugging failure of the coal feeder etc the outlet temperature of the coal mill can quickly climb to …
As drying for high-moisture coal requires more heat at a mill, the high-temperature gas at the mill inlet must be applied. Supposing that the moisture content in pulverized coal at the mill outlet is 30%, the gas temperature required at the mill inlet is considered to be approximately 450°C. Get Price

Two major parameters which decide the mill capacity and performance are the hardness of coal and the total moisture level in coal. The mill outlet temperature of coal-air mixture is maintained between 65 to 90 degree centigrade in the case of low and medium volatile coal. In the case of high volatile coal while the lower limit generally remains as 65 degree …
