4% fuel reduction through condensate recovery at a beverage plant in Indonesia

Condensate from the HTST cup section was being drained. Feedwater temperature was 27.7°C (81.8°F) and the condensate recovery factor was 0%. This resulted in a boiler steam to fuel ratio of 5.81 leading to higher fuel (palm shell) and water consumption.

Based on our site observation we recommended the installation of a Pressure Powered Pump Package Unit (PPPPU). Once installed, the system was able to recover condensate from the HTST cup section at 88°C (190.4°F), improving the feedwater temperature to 54°C (129.2°F). This led to an improved steam to fuel ratio and increased overall energy efficiency.
