A fuel of Qh = 6888 kcal/kg steam was bund in the furnace of a 223 m^2 water tube boiler which was generating 5443 kg steam per hour at 14.06 kg/cm^2 ab, d and s, fiom 109 °C feed, at a time when the fuel consumption was 612 kg per hour. (a) Find kcal rating and percent rating. (b) Calculate over-all thermal efficiency.
