Steam eductors have the potential for reducing the demand for steam during the evaporation of wort by up to 50% with low capital expenditure and without affecting the process of wort boiling or the flavour of beer. The theory describing the operation of eductors is discussed together with sample calculations for the prediction of performance. A small unit was installed on a kettle in the Holyrood pilot brewery to demonstrate the practicality of the principle and to obtain experience in operation. The unit performed in a manner in keeping with theory and had an efficiency of 90%. There is a great likelihood that the economic advantage of steam eductor systems will be very close to theoretical prediction.
