Info

OBSERVATIONS: ‣ The digestion <strong>of</strong> the infeed was immediate and very fast ‣ In the 2 hour period following the batch infeed, excess biogas was generated ‣ Also, during this time, the boiler could not consume all the biogas being generated and the excess was vented to atmosphere through the safety stack. ‣ During this first 2 hours, the boiler temperature did not rise relative to the extra gas being consumed and in fact, it occasionally dropped. ‣ There was little recoverable solids from the digester. ‣ Even though there was a large recycled digestate component to the infeed, the pH <strong>of</strong> the digester remained stable.
