Abstract
The use of auxiliary processes in the industry has become increasingly indispensable in the entire production chain by providing inputs such as water, steam, electricity, gas etc. Among these inputs, steam is one of the energy sources most used by the industrial sector. The numerous advantages in the use of steam as: ease of transport, high efficiency, high heat storage capacity, ease in obtaining and low cost compared to other energy sources, make it an indispensable and efficient way to transfer and generation power. The steam also has several applicability in manufacturing processes, such as temperature control and pressure, as the driving force in driving wireless network equipment (turbines, pumps, compressors, air blowers), the vacuum production ejectors in cleaning equipment and other. The steam system consists of five sections: pre-treatment, steam generation, steam distribution, end-use and recovery of condensate. All of these sections offer great opportunities for improvements to increase energy efficiency, helping in the reduction of production costs, maintenance and environmental impacts (CO2 emissions). Steam systems design, maintenance practices and methods of operations are the key factors for improvement. Examples of the performance of the entire vapor distribution system connected methods are steam quality specification and dimensioning of the boiler deaeration operation capacity, layout, piping design, drainage, dimensioning and maintenance of steam traps, accessories, starting and stopping the plant, radiation losses (insulation), leaks, equipment for heat recovery, desuperheating and treatment of boiler water. This article will discuss opportunities to reduce energy losses through a case study that will be presented to validate the options discussed, consolidating the importance of energy recovery through existing faults.
