Experimental study on drying coal slime by solar energy
Coal slime has low calorific value,high drying cost,and serious pollution.For the abovementioned problems,an experimental study on coal slime drying was conducted using solar energy as the heat source.The effects of solar irradiance and coal slime thickness on the coal slime drying were investigated.At the same time,their influence on the temperature of drying chamber was explored.The study results showed that,the ideal drying effect could be achieved when the solar irradiance was 500 W/m2.Increasing the thickness of coal slime was beneficial to the drying of coal slime.
