20th World Energy Congress
Energetyka 2008, nr 2, s. 95
Described is the course of the World Energy Council Congress held in Rome, Italy, Nov. 11-15, 2007, which motto was „Energy Future of the Interdependent World". Keynote addresses were given by Mr José Manuel Barroso, President, European Comission and Mr Pascal Lamy, Director General, WTO.
World reserves of energy raw materials
Energetyka 2008, nr 2, s. 99
Given is classification of energy raw materials resources and reserves by standards of WER. Specified is the amount of finite energy resources – mineral energy raw materials as well as renewable energy resources.
Nuclear Power Engineering during the World Energy Congress
Energetyka 2008, nr 2, s. 101
Nuclear power engineering was presented during the 20th World Energy Congress as technology of future which, against all fears, proved its dominative role in comparison with other electricity production methods. Its application can solve the problem of running out fossil fuels and ensure ecological process of electricity production. Necessity to develop it in the world of future was the key-thesis of Ms Anne Lauvergeon, Chair of the Executive Board, Areva, address.
Technological methods to reduce CO2 emission
Energetyka 2008, nr 2, s. 107
Reduction of CO2 emission coming from power energy sector will need widespread application of highly advanced generation technologies and effectiveness in energy consumption. Presented by the Electric Power Research Institute (USA) study results show that the most efficient method is to apply all solutions available while limiting their amount leads to cost increase.
Operating diagnosis of rolling bearings applied in motors used in power industry
Energetyka 2008, nr 2, s. 111
Presented are principles of envelope detection modified method elaborated by the author i.e. the method of rolling bearings operating diagnosis. Described is technology of taking measurements, given are results of exemplary diagnostic measurements taken on power industry auxiliary drives. Elaborated is evaluation criterion of rolling bearings technical condition as a result of many years industrial investigations. It is a simple criterion of bearings technical condition evaluation with the aid of measurement and analysis of bearing node vibrations acceleration signal.

Low temperature utilization of semi-dry flue gas desulphurization product
Energetyka 2008, nr 2, s. 127
Presented are investigation results of low temperature semi-dry flue gas desulphurization product utilization. Examined were two types of the product coming from different installations – they varied from each other with the product collecting method. Utilization process consisted in oxidation of CaSO3 to CaSO4 in an electrodynamic mill.

Building complex as energy system
Energetyka 2008, nr 2, s. 139
Proposed is application of interbranch flows theory („input-output analysis") for the needs of energy-ecological building complex analysis. This kind of approach can be used to compare different systems of power supply to a building. Formulated is linear mathematical model of annual energy balance of a building complex. Described is application of this linear model to calculate cumulative energy consumption coefficients and thermoecological cost in this complex. Presented mathematical model was used in an exemplary office building calculation.

Thermoeconomic analysis of technologies used in CHPs in Poland
Energetyka 2008, nr 2, s. 144
Characterized are basic co-generation technologies used in Polish municipal and industrial CHPs. The analysis appertains to coal pulverized fuel and CFB (Circulating Fluidized Bed) technologies, power unit adapted to heat production, combined cycle gas-turbine power plant fired with natural gas and industrial power and heating station fired with BFG (Blast-Furnace Gas) and coal. For each of the mentioned co-generation technologies an economic analysis was elaborated, determining NPV (Net Present Value) profiles.
Present state and perspectives of transport biofuels consumption in Poland in comparison with the UE 4th part. Actual conditions and consumption of biofuels in Poland. Biofuels of the 2nd generation
Energetyka 2008, nr 2, s. 149
In the world and also in Poland the systematic growth of the 1st genera-tion biofuels production is observed. There are big possibilities to develop domestic and foreign markets of the 2nd generation biofuels using the countries own energy biomass. Poland can deliver 12% (2200 PJ) of European energy biomass production (17.5 EJ/year), mainly from plough-lands, and its ability to produce biomass is the second one in Europe next to Ukraine (2800 PJ/year).
