1. What Is Steam Condensate Temperature?

Steam condensate temperature refers to the temperature of the liquid water formed when steam condenses. It is typically lower than the saturation temperature due to subcooling effects in condensate systems and heat exchangers.

2. How Does The Calculator Work?

The calculator uses the condensate temperature formula:

\[ T_{cond} = T_{sat} - \Delta T_{subcool} \]

Where:

\( T_{cond} \) — Condensate temperature (°C)
\( T_{sat} \) — Saturation temperature corresponding to steam pressure (°C)
\( \Delta T_{subcool} \) — Degree of subcooling below saturation temperature (°C)

Explanation: The formula calculates the actual condensate temperature by subtracting the subcooling amount from the saturation temperature at the given pressure.

3. Importance Of Condensate Temperature Calculation

Details: Accurate condensate temperature calculation is crucial for designing efficient steam systems, preventing flash steam formation, optimizing heat recovery, and ensuring proper condensate handling in industrial processes.

4. Using The Calculator

Tips: Enter saturation temperature in °C (based on steam pressure), subcooling amount in °C. Both values must be positive numbers with saturation temperature greater than subcooling.

5. Frequently Asked Questions (FAQ)

Q1: What is subcooling in condensate systems?
A: Subcooling refers to the temperature difference between the saturation temperature and the actual condensate temperature, indicating how much the condensate has cooled below its boiling point.

Q2: Why is condensate temperature important?
A: It affects flash steam generation, heat recovery potential, condensate pump operation, and overall system efficiency in steam plants.

Q3: What is a typical subcooling range?
A: Typical subcooling ranges from 0-10°C in well-designed systems, but can be higher in systems with poor heat transfer or excessive cooling.

Q4: How does condensate temperature affect flash steam?
A: Higher condensate temperatures result in more flash steam when pressure is reduced, while lower temperatures reduce flash steam generation but may indicate heat loss.

Q5: What factors influence condensate temperature?
A: Heat exchanger design, insulation quality, ambient conditions, condensate flow rate, and system pressure all affect the final condensate temperature.
