A furnace of 250 MW rating is used to melt and raise the temperature of aluminium from 25\(^{\circ}\)C to 900\(^{\circ}\)C. Aluminium has a solid-state specific heat, latent heat, and liquid-state specific heat of 0.9 kJ/kg-K, 390 kJ/kg, and 1.108 kJ/kg-K, respectively, and the furnace has 70% efficiency. The melting point of aluminium is 660\(^{\circ}\)C. The amount of aluminium that can be processed per hour is ________ kg (rounded off to 1 decimal place).
