RESUMO:

The present study was developed with the objective of evaluating, in a technical and economic way, the behavioral change between the preventive strategies of an air condensing turbine (Model: H3800S), applied in an industrial chemical plant that produces fertilizers, sulfuric acid and installed in Brazil, city of Araxá / MG. The industry has a recovery boiler, generating an overheated steam at a temperature of 400 ° C, and a pressure of 4.3 MPa, which is directed to a steam turbine coupled to an electric generator, thus constituting a turbogenerator group (GTG ) with 11.50 MWe electric power generation capacity (Wele). The generated Wele was made available to be consumed by an industry and represents 22.45% of the total consumption, if it is operating at nominal capacity. The generation capacity of this GTG in the period between preventive maintenance is influenced by the internal losses that occur in the turbine and the steam in an environment of three sources: friction between moving doors, fluid leaks and friction in labyrinth seals of steam. The operation of the steam turbine reduced the generation capacity and, consequently, negatively impacted the cost of an installation of this unit, due to the capacity of production of greater amount of electric energy (Eele), made available by the concessionaire that serves a region of installation industry. The only thing is minimized when a steam turbine is used in this GTG undergoes periodic preventive maintenance in order to reconstitute or replace the worn or damaged components.
