COST OF THE ELECTRICAL ENERGY OBTAINED BY COGENERATION IN THE SUGAR CANE MILLS. PART I. METODOLOGY

Abstract

In most of the sugar cane mills there are the consumers of steam (process). They work to a very small pressure in comparison with the obtained one in the steam boilers which is increased even more if there is over heaters. To obtaining this pressure required one by process it become necessary to pass through a reducing valve to down pressure. If this steam goes by against pressure turbine and generating electric power, it
takes advantage energy that would get lost in the reducing valve another way, constituting a source of energy saving
