Boiler Energy = Steam Energy Flow + Blowdown Energy Flow - Feedwater Energy Flow.

Blowdown Energy Flow = Specific Enthalpy * Mass Flow.

The Specific Enthalpy is then multiplied by the Mass Flow to get the Energy Flow: Using the Steam Property Calculator, properties are determined using Steam Pressure and Quality = 0 (Saturated Liquid). Step 3: Determine Blowdown Properties and Mass Flow Using the calculated feedwater mass flow and blowdown rate:

Feedwater Energy Flow = Specific Enthalpy * Mass Flow.Using the Steam Property Calculator, properties are determined using Deaerator Pressure and Quality = 0 (Saturated Liquid). Feedwater Mass Flow = Steam Mass Flow /.Steam Mass Flow = Feedwater Mass Flow - Feedwater Mass Flow * Blowdown Rate.Steam Mass Flow = Feedwater Mass Flow - Blowdown Mass Flow.Blowdown Mass Flow = Feedwater Mass Flow * Blowdown Rate.Step 2: Determine Feedwater Properties and Mass Flow The feedwater flow rate can be calculated from steam mass flow and blowdown rate: Steam Energy Flow = Specific Enthalpy * Mass Flow.

Calculation Details Step 1: Determine Properties of Steam Produced Using the Steam Property Calculator, properties are determined using Steam Pressure and the selected second parameter (Temperature, Specific Enthalpy, Specific Entropy, or Quality).
