Drying Coal by Microwave

Using the above data, estimates for large-scale drying can be projected. For example, to process a wet feed of 10 st/h (9,080 kg/h) and remove 10 pet moisture with an overall microwave absorption efficiency of 95 pct, 620 kW of microwave power would be required. This assumes that 1 kW-h of microwave energy evaporates 3.4 lb (1.54 kg) water.get price
