Summary: The research activities are concernd with establishing an energy management program in an organized way of energy savings, rational use and environment protection. The energy analysis is developed in the frame of conservation, efficiency and ecology terms. Most of the energy consumed is obtained from fossil fuels with limited reserves and an adverse effect on the environment. It therefore becomes necessary to find a way to reduce consumption and also to replace fossil fuels. This necessity includes energy conservation, i.e. energy savings, rational use of energy and substitution of one form by another. By reducing total fuel requirements the amount of rejected exhaust gases and also thermal and chemical environmental pollution will diminish. The project activities are carried out in following closely connected areas: a) energy management in industrial systems, including process system optimization with respect to thermodynamical, economical and environmental demands, plant efficiency and energy savings; b) waste heat economizing in the frame of waste energy reduction, low, medium and high temperature heat recovery, cogeneration and effect on environmental pollution; c) alternative conventional and renewable sources with respect to availability, possibility for substitution and economics; d) environmental pollution in respect of sort and quantity of fuel and particularly flue gases desulphurization processes. The research results are being published in domestic and international journals (12), presented on congresses and printed in domestic and international proceedings (25).

Keywords: energy audit, accounting and management, sources, consumption, process efficiency, optimal use, conservation, exhaust gases, condensate heat, heat recovery, cogeneration, CHP systems, alternative sources, substitution, renewable sources, solar radiation, wind energy, HVAC systems, ventilation losses, hydro generator cooling, environmental pollution, flue gases treatment

Research goals: The aim of search was the analysis of energy influence as an input to the whole network of industrial processes. This project has been developed to provide guidelines for the more efficient processes related to energy management based on sustainable development. The expected significant improvement of basic and advanced development works are analysed and presented. The most important step which can be taken with respect to energy management is to insure that the advantages of the proposed approaches are considered in energy planning and using. The treatment is carefully chosen to provide the right depth of energetic background. It is evident that energy consumption could be reduced through conservation based on greater efficiency in utilization. Therefore it is necessary to identify how many different forms of energy are spent, what they are used for and how efficiently they are used. Having collected relevant data and analyzed energy use the next stage is to examine ways in which energy management can be improved. In industrial processes it is also important to determine the relationship between energy production and ecology. In many processes there are valuable energy savings to be made by waste heat recovering from plant and using it to preheat incoming cold streams (boiler feed water, air to burners, fuel, process raw materials, space heating application). Also the exhaust gases are important for determining efficiency and environmental pollution. In regard to environment, a treatment of ecological impact caused by energy processing is searched out and some proposals are given. The relevant problems with respect to rejected heat from industry and power stations are searched. The renewable alternative sources such as solar and wind energy in relation to energy conservation are also analyzed. The presented investigation results in some energy saving proposals including benefits. As the basis some characteristic industrial processes and changes in the energy supply are elaborated.
