Opis:
Reduction of CO2 emissions in Poland (excluding transport) should be related to a change in the structure of electricity production sources. Similar actions have been taken by many European countries. In 2017, in the European Union’s power industry, the largest emitters were dominated by coal-fired power plants in Germany (seven power plants). However, the leader of this ranking turned out to be the Belchatów power plant owned by the Polish Energy Group (PGE). Renewable energy is energy obtained from natural processes. It should be obtained in a way that would not cause a deficit of natural resources (renewed in a short time) to have a limited impact on the environment. The purpose of promoting and using renewable energy sources (RES) is to reduce the harmful effects of energy on the natural environment, primarily by limiting greenhouse gas emissions (water vapour, CO2, CH4, CFC, N2O, halon, ozone and industrial gases HFC, PFC, SF6). Biomass is the most widely used renewable energy source currently used. The study of the literature and comparison of the set parameters for different types of biomass in the given order shows that Virginia mallow has the highest usefulness for energy purposes. Considering the fact that both cashew and coconut (shells) cannot be grown due to the climate prevailing in Poland, Virginia mallow seems to be the best alternative for traditional fuels used in the energy sector in the analysed group. Virginia mallow has competitive properties to wood biomass and hard coal only significantly supercedes in terms of calorific value. The energy properties of Virginia mallow can additionally be improved as a result of the torrefaction process. In addition, in the literature on the subject, attention is paid to the fact that mallow may be grown on less-favoured soils and the process of its collection – in contrast to other such plants – does not require the use of specialized agricultural machinery.

Opis:
The combined production of electrical and heat energy is one of the preferred, by national policy, activities associated with energy production from renewable sources. The simultaneous generation of heat and electrical or mechanical energy during the same technological process is called cogeneration or combined heat and power, CHP. The presented methodological approach includes an analysis of the data recorded in the research stations and agricultural production stations owned and managed by the University of Warmia and Mazury (UWM) in Olsztyn, performed in order to determine the energy potential of biomass and other renewable energy sources (RES). Depending on the substrates available for UWM in Olsztyn, it is proposed to take a varied approach towards the use of RES by means of biotechnological and thermal biomass conversion. The first method is based on the production of biogas from biomass with the subsequent use of the generated biogas in the process of cogeneration. In the second method, heat energy generated by gasification in a syngas generator will be used for transformation with a Stirling’s engine into mechanical energy and finally into electrical (30%) and heat (60%) energy. The concept of a “Green University” is the result of the performed analyses.

Opis:
This paper presents a concept and a technical analysis of a co-generation power set with a combustion engine powered by syngas produced in the process of wood waste gasification. The set is composed of a wood waste gas generator fitted with a filter system, a combustion engine, a current generator and heat exchangers. The foundations of the gasification process are described together with the most common solutions used worldwide. Moreover, the methods of adapting spark-ignition and compression-ignition engines to be powered by syngas produced in the wood waste gasification process are presented. The advantages of the presented solution and its possible applications in industry are shown. The assumed technical parameters of the set are as follows: mechanical-electrical energy – 200 kWh, heat recovered from the gasifier – 250 kWh, heat recovered from the engine – 200 kWh. The concept and design of the module cogeneration set is the effect of actions taken by the Institute of Automobiles and Internal Combustion Engines and by the Institute of Thermal Power Engineering of the Cracow University of Technology.
