Thirty Years of Bełchatów Power Station
Energetyka 2005, no. 8, p. 515
There is presented briefly thirty years of existence of Bełchatów powerstation, which history began in sixties of the previous century. Discoveryof gigantic, in Polish conditions, lignite resources began so called Bełchatów epopee. Bełchatów power station belongs to day to the BOT Group and it generate in the XXI century the cheapest and the cleanest electric energy.

Development of BOT Bełchatów Power Plant plc. as Essential Element of BOT GiE plc. Strategy
Energetyka 2005, no. 8, p. 517, fig. 1
BOT Mine and Power Industry plc. holding rose up as a strategic power resource and it guarantees now the market stability in Poland. Development strategy of Bełchatów power station is subordinated to the competition requirements in contemporary European energy market. In the face of dynamic changes in Europe there is no alternative for the development way for Bełchatów power station, except of the present strategy assuring rational use of accessible lignite deposits and achievement of high operational parameters with concordance with ecological requirements.

Modernisation of HP and MP Parts of 18K370 Turbine and Their Auxiliary Systems in Bełchatów Power Station
Energetyka 2005, no. 8, p. 521, 7 figs, 1 tab.
The turbine design is based on solutions of the BBC turbines from early seventies of previous century. Guarantee measurements proved that LP parts of the turbine had considerably lower efficiency than their calculated efficiency. It was the reason for the first stage of the turbine modernisation in 1997 (it was the modernisation of LP part, so improvement of their efficiency and as a result the output of the power unit rose to 370 MW) The second stage of the turbine modernisation is planned since 2007; main objective of this modernisation is to extend the life time of the turbines above 320 000 h. and to increase the efficiency of the HP and MP parts of the turbines resulting in decrease of the unit heat consumption to 7 832 kJ/kWh.

Carried-out and Planned Modernisation of Technological Equipment in Machine Hall and Their Influence on Improvement of Availability and Efficiency of Equipment
Energetyka 2005, no. 8, p. 526, 14 figs
Equipment in the machine hall in the technological system of the 360 MW power unit similarly like the boiler equipment is the essential one and largely influences technical and operational indices of the power unit operation and its availability. These indices were taken into account during the design works and at choice of the suppliers of the essential equipment in the machine hall for the 360 MW power unit in Bełchatów power station. At the choice was taken into consideration their modern design solutions.

50. Anniversary of I Transformer Conference 1955-2005. Co-creators of Success and Their Scientific and Technical Achievements Seen after Years
Energetyka 2005, no. 8, p. 550, 1 fig., 21 refs
From the perspective of the half of the century the merits for the science and industry of Professor Eugeniusz Jezierski (he was called the creator of "Łódź transformer school") have been unquestionable and adorable. In the paper are also mentioned and characterised other domestic centres, which activity caused in 1955-1985 the achievement of exceptional acceleration in the domestic transformer manufacturing and rose the transformer operation level.
Losses in Transformers for Converters of Twelve-Pulse, Two-Bridge Type with Concentrated Secondary Windings Originated from Current Higher Harmonics
Energetyka 2005, no. 8, p. 556, 6 figs, 3 refs
Dispersion fluxes caused by higher harmonics of the current in converter transformers designed for twelve-pulse systems with condensed windings can cause thermal failures of the winding insulation. It concerns especially the harmonics inducing the transversal flux. In order to avoid the overheating, the design and dimensions of the conductors in particular windings should fulfil defined conditions. Commissioning tests should enable to check the fulfilment of these conditions.
Synchro transmitter excitation protection systems and their collaboration problems with control systems
Energetyka 2005, no. 8, p. 561
(ZPBE Energopomiar Bulletin p. 33), 4 figs, 12 refs
Presented were protection systems being the excitation systems autonomous equipment as well as protection systems reacting to interferences and damages occuring in excitation systems being electric blocks protection systems elements. Mentioned was the protecion systems collaboration with control systems and some ways the protection systems influence block executive elements.
Selected problems concerning carbon dioxide mass calculation in furnace gas (essential to realize 2003/87/WE Directive)
Energetyka 2005, no. 8, p. 567
(ZPBE Energopomiar Bulletin p. 39), 1 figs, 3 refs
Presented were some problems connected with atmosphere emitted carbon dioxide - produced in big power boilers during brown and hard coal burning - mass calculation. Burned coal parameters influence on emission quantity was presented. Decribed were methods of taking into consideration - during calculating - the combustible parts content in furnace wastes as well as carbon monoxide amount in combustion gases.
Turbine oils deterioration products and solid impurities test methodology modernization.
Energetyka 2005, no. 8, p. 571
(ZPBE Energopomiar Bulletin p. 43), 1 fig, 6 tabs, 15 refs
Presented was - elaborated and used by Energopomiar - a new turbine oil consumption quantity assessment infrared spectrophotometry method. The correct sampling procedure - considering oil purity ensuring necessity - was the matter at issue as well as impurities level coding methods in the light of the latest standards.
