Introduction
A Condensate Recovery Tank (CRT) is a specialized boiler auxiliary pressure vessel designed to collect, store, and return condensed steam from industrial and commercial processes back to the boiler system. By recovering and reusing condensate, these tanks enhance energy efficiency, reduce water and fuel consumption, and protect boiler systems from thermal shocks and water treatment issues.
At NORDSTONE., we design and manufacture ASME-certified condensate recovery tanks with robust construction, precise thermal design, and compliance with international standards, including ASME Section VIII, NB, and PED certification.
What is a Condensate Recovery Tank?
A Condensate Recovery Tank is a pressurized or atmospheric vessel that receives condensate from steam systems, allowing it to cool, separate non-condensable gases, and store it for return to the boiler feedwater system. This reduces energy consumption, minimizes chemical treatment costs, and ensures consistent boiler operation.
Key components include:
- Cylindrical or horizontal vessel shell designed for pressure and temperature requirements
- Condensate inlet connection from steam traps and process condensers
- Vent for non-condensable gases
- Outlet to boiler feedwater system
- Internal baffles or demisters to separate flash steam
- Manways for inspection and maintenance
- Instrumentation ports for level, temperature, and pressure monitoring
Condensate recovery tanks are critical for energy optimization, environmental compliance, and long-term boiler system reliability.
