This work presents an analysis of a cogeneration plant of a sugarcane industry of Sao Paulo State (Iracema) that privileges the commercialization of the bagasse surplus because it is located in a region where the consume of bagasse by the local industries is intense. The plant is composed by five boilers that produce 470 ton/h of steam at pressure of 2,2 MPa and temperature of 300ºC and back-pressure turbines of simple stage for energy generation and for driving the millings, cutters, shredders, pumps and exhaust fans. Part of the steam generated is also utilized to supply consume of an associated company (OMTEK) that it produces acid ribonucleic and the bagasse excess is commercialized. For this, a thermodynamic study is made, as well as a detailed analysis of the technical and economical viability, determining some performance indexes, the global efficiencies, as well as the costs of production of electric and thermal energy.
