A steam generator evaporates \(18000 \mathrm{~kg} / \mathrm{h}\) of steam at 12 bar pressure and steam is \(97 \%\) dry. Feed water temperature \(=105^{\circ} \mathrm{C}\). Coal is fired at the rate of \(2050 \mathrm{~kg} / \mathrm{h}\). C.V. of coal is \(27400 \mathrm{~kJ} / \mathrm{kg}\).

Calculate

(a) Heat supplied/h

(b) Thermal efficiency

(c) Equivalent evaporation.
