Indigo Agglomerator as Proven Technology for Reducing Visible Emissions from Electrostatic Precipitators
Energetyka 2005, No. 11, p. 751, 6 figs, 4 tabs
The Indigo agglomerators have been installed in five power stations, fuelled with a wide range of coals, providing for a long time a significant improvement of the electrostatic precipitator performance. The electrostatic precipitators in these power stations differ each other with regard to their designs (as European, as American ones as well), and the boiler arrangements and outputs are differentiated also. The coals burnt include a range of Australian, Colombian, as well as US Western and Eastern coals. During the operation of the agglomerators in the period in excess of two years the reduction of the mass emission of fly ash and the opacity after the electrostatic precipitators has been achieved, respectively in the range of 30-60% and 50-80%, so the Indigo agglomerators can be considered now as a proven technology for reducing emissions from electrostatic precipitators and suitable for increase of the de-dusting efficiency of the precipitators in the industrial conditions.

Operational Experiences of Pilot Conditioning Installation of Flue Gas before Electrostatic Precipitator
Energetyka 2005, No. 11, p. 764, 6 figs, 14 refs
Conducted investigations have enabled elaboration of a conditioning technology of the flue gas from lignite fuelled boilers. An essential feature of the fly ash being hovered together with flue gas is a great content of CaO; during conditioning with the water or solutions it creates hydroxides reacting with the SO2, HCl and HF. In the case of the lignite from Turów Day Light mine containing small quantities of CaO there is necessary to inject CaCO3 to the boiler.

Visualising Systems of Power Unit Operation in Bełchatów Power Station
Energetyka 2005, No. 11, p. 772, 5 figs
To the systems assuring visualising of the power unit operation one can count ASIX visualising system of the technological data together with the subsystems processing analogue measurements and signals from bistable gauges, as well as MASTER FT/NT visualising and control system of the turbine operation. The ASIX system was for the first time implemented in Bełchatów power station for the power unit No. 6 in 2000 by AKSOM Ltd.

Live Line Works at Power Equipment and Wiring Systems
History of Development of Live Line Works
Energetyka 2005, No. 11, p. 783, 7 figs
Utilisation of the live line work technology at maintenance of electric power lines began from use of insulating sticks for opening the disconnecting switches. This operation proved that long wooden sticks could be equipped with accessories enabling electricians secure work on live lines. As the begin of live line works the year 1913 is recognised in some publications. In the paper national and international conferences on live line works are mentioned.

DGA Usefulness in Commissioning Tests of Oil Transformers
Energetyka 2005, No. 11, p. 798 (Bulletin of ZPBE Energopomiar p. 80), 4 figs, 1 tab., 8 refs
Problems of the use of DGA (Dissolved Gas Analysis) test method for factory tests of new and modernised transformers are presented. Presented are testing equipment and criteria of result assessment. Experiences of multi-year use of the method during the factory tests and attestation tests of constructional materials are discussed. Given are - as examples - characteristic results, substantial conclusions and suggestions, as well as directions of the amendment of the pertinent IEC standard.
Occurrence of Colloidal Silica in Natural Water and Removing it from Water Conditioned for Power Purposes
Energetyka 2005, No. 11, p. 802 (Bulletin of ZPBE Energopomiar p. 84), 4 figs, 1 tab., 8 refs
Discussed are problems of occurring the colloidal silica in the feed water for water-steam cycles in the power industry and heating systems. Sources of colloidal silica in natural waters and its structure and properties are presented. An overview of methods of removing the colloidal silica during the water conditioning is made. An attention is paid to the harmful influence of the silica on the operation of the water conditioning plants and power equipment.
Controlling Electricity Demand under Electric Energy Market Conditions
Energetyka 2005, No. 11, p. 811 (Bulletin of Instytut Energetyki p. 13), 4 figs, 1 tab., 8 refs
Discussed are control systems of electricity receivers, including the control system with the use of the acoustic frequency elaborated in eighties of previous century in Gdańsk Branch of Polish Power Institute and successfully utilised in some distribution companies; the scope of its use can be substantially extended at present in the conditions of the electric energy market operation. Following equipment designed for the control systems of electricity receivers is characterised: any accumulation heating furnaces, water heaters of container type, steamers used in farms and air conditioning equipment.

Clean Energy from Łaziska Power Station
Energetyka 2005, No. 11, p. 816, 6 figs, 14 refs
Above 15 years ago Łaziska power station was registered in the list of 80 the most oppressive plants for the environment in Poland. To day the power station has disappeared from this list and it could operate without any limitations in every of the most developed EU countries now. It fulfils with surplus every ecological standards now. Thanks to huge effort of the management team and staff, many inventions and innovations and great fin ancial expenditures and first of all - a clear development vision, the power station has become the modern, human and environment friendly plant, with a history of near 90 years. The management team and power station staff is convinced that the power station is one of only few such cases in Poland, European Union and even in the world. It is proved by numerous national and foreign diplomas, certificates and awards.
