A boiler is used to heat steam at a brewery to be used in various applications such as heating water to brew the beer and sanitizing the brewing tanks. 81.0% of the heat produced by the boiler is used to create saturated steam at 18.0 bars (absolute) from liquid water at 20° C. If 1.80 × 102 m3/h of steam is needed, what rate of heat does the boiler output?
