Abstract

The article compares the energetic qualities of fuels from waste with hard coal. A cogeneration system has been modeled based on the organic Rankine cycle (ORC) powered by the investigated fuels in order to identify possibilities as well as problems in use of fuels from waste in an exemplary cogeneration unit in distributed generation. The emission of thermal transition of the investigated fuels has been calculated on the basis of their energetic use in order to determine the aggregate impact on the environment, people’s health and the ecosystem. In order to conduct the research, Ebsilon Professional and SIMAPro software were used. The article demonstrated the energetic and ecological validity of the use of fuels form waste in small-scale combined heat and power (CHP). The energetic potential and influence on the environment, people’s health and the ecosystem depends on the quality of fuel, but the strict regulations for generating fuels from waste and the flexibility in forming them, allow for a product which is more beneficial economically and ecologically than hard coal.

Highlights

  • The major part of European energy technology is based on hard and brown coal

  • Regarding energetic plans among the members of the EU, the majority of generated electrical and heat energy is going to be distributed generation which will allow the improvement of energetic security, including a constant supply of high quality energy which is going to influence the development of the economy in EU countries and limit climate destruction [1,2,3,4]

  • Generating energy in distributed generation might be based on renewable sources of energy, such as solar energy, wind energy, and high-performance cogeneration powered by biomass or fuels from waste

Summary

Introduction

The major part of European energy technology is based on hard and brown coal It involves high emission of carbon dioxide which is in contradiction to European Union Policy and its aims. It strives for complete elimination of coal power plants in an energetic mix among member states. Generating energy in distributed generation might be based on renewable sources of energy, such as solar energy, wind energy, and high-performance cogeneration powered by biomass or fuels from waste. Biogas produced as a result of anaerobic digestion can empower a cogeneration system with the power of that particular
