Resumo:
The current work analyses the influence of steam generation parameters elevation,
application of condensing-extraction steam turbines and electrification of cane milling drives
over the efficiency of sugar industry cogeneration systems. The evaluation of the magnitude
of electricity production expansion provided by these measures and the economic feasibility
of their implementation considering the carbon credits trading is also carried out. The
electrical energy production and exporting capabilities, cycle efficiency and fuel consumption
are determined by means of simulation of the cogeneration systems of three sugar cane
processing plants for the actual operation conditions, as well as, for the improved systems,
and combined with the investment and O&M costs, produced electricity and emission
reduction certificates sales prices for the economical assessment of each proposed
configuration.
