Cogeração de energia com biomassa: balanço energético para diferentes vazões de vapor

Abstract

The work shows concisely the way how the Bioener thermoelectric power plant, placed in the city of Rivera - Uruguay, works. The power plant operates on a based Rankine cycle of cogeneration where steam is produced to the URUFOR timber located beside the power plant for the Administración Nacional de Usinas y Transmisiones Eléctricas (UTE). The object of study was the simulation of energy balances varying the mass flow of steam generated to determine which power steam shows the best SOLD ENERGY/ USED FUEL ratio. Probably there was an influence of the use of air condensers on the internal consume of the power plant, thus changing the final net energy delivered by the company to the UTE. For that the fluid and the fuel properties were analyzed in different machines and equipment present on the steam and biomass cycles trying to include as many points of the power plant on the balance as possible.
