1. What is Steam Condensate Recovery?

Steam condensate recovery refers to the process of collecting and reusing condensate water that forms when steam loses its latent heat and returns to liquid state. This recovered condensate can be reused in boiler systems, improving energy efficiency and reducing water treatment costs.

2. How Does the Calculator Work?

The calculator uses the condensate recovery formula:

Where:

• \( Condensate\ Returned \) — Amount of condensate collected and returned to the system (kg)
• \( Total\ Generated \) — Total amount of steam generated by the boiler (kg)
• \( Recovery \) — Percentage of steam condensate successfully recovered

Explanation: This calculation measures the efficiency of your condensate recovery system by determining what percentage of generated steam is successfully returned as condensate for reuse.

3. Importance of Condensate Recovery

Details: High condensate recovery rates significantly reduce energy consumption, lower water treatment costs, decrease boiler feedwater requirements, and improve overall system efficiency. Recovered condensate is already treated and hot, requiring less energy to convert back to steam.

4. Using the Calculator

Tips: Enter the amount of condensate returned to the system and the total steam generated, both in kilograms. Ensure measurements are taken over the same time period for accurate calculations. Values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is considered a good condensate recovery rate?
A: Recovery rates above 80% are generally considered excellent, while rates below 50% indicate significant improvement opportunities. Ideal rates depend on specific system design and application.

Q2: Why is condensate recovery important for energy efficiency?
A: Condensate contains about 25% of the original steam's energy. Recovering this heat reduces fuel consumption by 10-20% and lowers CO2 emissions.

Q3: What factors affect condensate recovery rates?
A: System design, steam trap efficiency, piping insulation, condensate pump performance, and steam pressure all impact recovery rates.

Q4: How can I improve my condensate recovery rate?
A: Regular steam trap maintenance, proper insulation, eliminating steam leaks, optimizing condensate return piping, and installing efficient condensate pumps can improve recovery rates.

Q5: What are the economic benefits of high recovery rates?
A: Each 10% increase in condensate recovery can reduce fuel costs by 1-2%, lower water treatment costs by 5-10%, and decrease makeup water requirements by 10-15%.
