Condensate formed by the condensation of steam is hot, pure and purified water. Every ton of condensate discharged to the drain means the loss of both heat and water and water treatment chemicals. This tool calculates the annual fuel, water and treatment savings to be obtained by returning the condensate to the boiler.
Formula
Fuel economy = Q · hours / (efficiency · calorific value)
Example
A plant that returns 2,000 kg of condensate per hour at 90 °C gains 174 kW of heat compared to 15 °C mains water. In a natural gas boiler (90% efficiency), this means approximately 121,000 Sm³ of natural gas and 12,000 m³ of water savings in 6,000 hours per year. With 10 ₺/Sm³ gas and 40 ₺/m³ water + treatment cost, the annual savings exceed 1.7 million ₺.
You can also use the flash steam calculation to recover the flash steam from the pressurized condensate. To evaluate your steam system as a whole, you can take a look at our steam boiler guide and get a free quote for your project.
