Steam Calculators: Boiler Calculator

[ Steam Energy Flow = 158859 = 1680.5 btu/lbm * 89.6 klb/hr] Step 2: Determine Feedwater Properties and Mass Flow The feedwater flow rate can be calculated from steam mass flow and blowdown rate: Blowdown Mass Flow = Feedwater Mass Flow * Blowdown Rate; Steam Mass Flow = Feedwater Mass Flow - Blowdown Mass Flow
