IMPROVED BOILER CONTROL IN FOOD FACTORIES
This project was undertaken to explore the possibilities of making useful energy savings in an actual factory by making a continually updated forward forecast of steam demand, which would be used to manage the steam generation and distribution system in the most cost effective manner. A data-logging computer with steam and oil meters and other sensors was installed by the host company + an edible oil refiner. Data were obtained on boiler combustion efficiency, relative proportions of high and low pressure steam, the main steam using areas and plant and the magnitude and timing of steam demands for individual operations. A number of energy conservation opportunities was identified that, if implemented, would significantly affect the steam demand. A control strategy for the boiler system was proposed which, by the use of forward load forecasting, would prevent coincidence of demand from two major intermittent steam users that could adversely reduce pressure on the high pressure main. It was concluded that the firm would not proceed with load forecasting because considerable energy savings were identified by the first part of the study which would reduce the load on the boilers. When the load on the boilers is reduced the additional savings that can be made by load allocation and peak shedding are not sufficient to justify the expenditure required in the present circumstances of the host company.
