Title : Heat Recovery in Air Compressors
Abstract:
Compressed air systems are widely used in industry. Compressed air is usually produced by a compressor driven by an electric motor. Large part of the energy is converted to waste heat and its recovery prevents losses to a large extent in compressed air production. In this paper, a literature review about compressed air systems is given. In the paper, the system principle, structure and types of compressors are introduced, how the compressors can be operated more efficiently and savings opportunities are mentioned. Savings opportunities are explained with calculation methods. Compressor selection criteria are explained and advantages and disadvantages of compressor types are listed. This study, which aims to point out the compressor-induced energy losses in the industry by choosing the right compressor and calculating the savings opportunities, also includes methods that can be applied regarding energy efficiency. In the study, it is mentioned how the waste heat in the compressors will be converted into useful heat.
