1. What is the Condensate Formula?

The condensate formula calculates the amount of condensate produced from steam based on enthalpy values. It is derived from the first law of thermodynamics and energy balance principles in steam systems.

2. How Does the Calculator Work?

The calculator uses the condensate formula:

Where:

• \( Condensate \) — Amount of condensate produced (kg)
• \( Steam \) — Amount of steam input (kg)
• \( h_{steam} \) — Enthalpy of steam (kJ/kg)
• \( h_{cond} \) — Enthalpy of condensate (kJ/kg)
• \( h_{fg} \) — Latent heat of vaporization (kJ/kg)

Explanation: The formula calculates condensate mass based on the energy difference between steam and condensate, normalized by the latent heat of vaporization.

3. Importance of Condensate Calculation

Details: Accurate condensate calculation is crucial for steam system design, energy efficiency analysis, condensate recovery system sizing, and overall thermal system optimization.

4. Using the Calculator

Tips: Enter steam mass in kg, enthalpy values in kJ/kg. All values must be positive numbers. Ensure enthalpy values are consistent (same reference state).

5. Frequently Asked Questions (FAQ)

Q1: What is the typical range for h_fg?
A: For water at atmospheric pressure, h_fg is approximately 2257 kJ/kg, but varies with pressure and temperature.

Q2: How do I determine h_steam and h_cond values?
A: Use steam tables or thermodynamic property software based on the pressure and temperature conditions of your system.

Q3: Can this formula be used for all steam systems?
A: Yes, but ensure enthalpy values are accurate for the specific pressure and temperature conditions of your application.

Q4: Why is condensate recovery important?
A: Condensate recovery saves energy (heat content) and water treatment costs, improving overall system efficiency.

Q5: What factors affect condensate quality?
A: Steam purity, system pressure, temperature, and the presence of non-condensable gases can all affect condensate quality.
