Abstract
Effective use of utilities in production plants is an issue that is becoming increasingly significant in energy policy of Europe. Production of compressed air consumes 3% of the total electricity consumption in Europe. In order to produce compressed air, approximately 10-20% of electricity transferred to compressor is used, the rest is lost due to lack of tightness and heat losses. The aim of this work is to evaluate the possibility to install recovery systems on air compressors to recover the lost waste heat and its management for the needs of heating office buildings/production halls and analysis of investment profitability. The investment will be supported by co-financing in the form of energy efficiency certificates (so-called white certificates), which the production plant will be able to sell after receiving them from Polish Energy Regulatory Office in return for completing an investment that consists recovering waste heat from air compressors.
Highlights
In the present world, increasing importance is attached to conducting activity in harmony with sustainable development of a company
There is a great potential of energy we can save/recover from compressed air systems
The aim of the work is to analyse profitability of installing recovering heat systems on compressors in Bulten Poland S.A. and estimate simple payback time (SPBT). This will help in order to being independent from heat supplier and will lead to reuse waste heat for their purposes, reducing simultaneously CO2 emission and increasing energy efficiency in the company
Summary
In the present world, increasing importance is attached to conducting activity in harmony with sustainable development of a company. The electricity generation using this fuel is characterized by a high index of emission Due to this fact, the effectiveness of the energy use by the enterprises have to increase. The standard emission index of the electricity generated in Poland equals to 1.191 t CO2/MWh, whereas the European average equals to 0.460 t CO2/MWh [2]. The aim of the work is to analyse profitability of installing recovering heat systems on compressors in Bulten Poland S.A. and estimate simple payback time (SPBT). This will help in order to being independent from heat supplier and will lead to reuse waste heat for their purposes, reducing simultaneously CO2 emission and increasing energy efficiency in the company. This study will analyse simple payback time of proposed solution with and without taking into account energy efficiency certificates to show the big value of the motivation in the form of white certificates
