Plant Engineering Calculator

Condensate Recovery Energy Savings Calculator — Heat, Water & Fuel

Estimate recoverable sensible heat in returned condensate relative to makeup water, then convert it to boiler-fuel equivalent and annual energy value.

Inputs

Results

Recovered sensible heat 139.53 kW
Fuel-input equivalent 164.16 kW
Annual fuel energy avoided 984941 kWh
Annual value $39398

Formula

Q=m·Cp·(Tcond−Tmakeup); fuel equivalent=Q/ηboiler.

Worked example

Returning 2,000 kg/h condensate 60°C hotter than makeup carries roughly 139 kW of sensible heat using water Cp≈4.186 kJ/kgK.

Assumptions & limits

  • This screen values sensible heat only; flash-steam recovery is a separate thermodynamic job.
  • Account for actual condensate quality, contamination and return-system losses.

FAQs

What does this Condensate Recovery Energy Savings Calculator calculate?

Estimate recoverable sensible heat in returned condensate relative to makeup water, then convert it to boiler-fuel equivalent and annual energy value.

Can I use the result for final equipment selection?

Use it as a transparent engineering and energy-screening result. Verify final decisions with measured site data, OEM curves, applicable standards and operating limits.

Why does MAXScanner show assumptions?

Plant calculations can look exact while depending heavily on operating assumptions. Showing them makes scenarios auditable and easier to compare.
