Energy audit case studies I—steam systems

This paper presents an analytical diagnostic tool for energy audit of steam systems. The circuit efficiency is determined as a product of the segment efficiencies. The analysis is applied to a few industrial cases. These will provide clear indication on the pattern of energy losses and will aid in decision support for evolution of energy conservation measures. The results indicate that contrary to the popular thrust areas, the steam lines and the condensate loss are the major causes of fuel energy wastage and these offer considerable potential for conservation.
