Three-dimensional Modelling of Coal Combustion in the Power Boiler with the Tangential Furnace
Energetyka 2004, No. 3, p. 145, 5 tabs, 9 figs
Presented is three-dimensional simulation of flow processes and combustion in the tangential furnace of the power dust boiler of OB-380 type manufactured by the RAFACO SA and operated in the Oslomej Power Station Kicevo - Macedonia).
The CFC Fluent software was applied as and technical data of the boiler is given.
Thyristor Triggering Systems
Energetyka 2004, No. 3, p. 1 52, 5 figs, 9 refs
Given are two ways of the ignition pulse control: individual triggering and parallel triggering. Both systems are compared. Operation of limiters and digital triggering systems are described.
Electric Power Installations of High Voltage - Minimal Distances
Energetyka 2004, No. 3, p. 156
Requirements of new Polish standard PN-E-05115 concerning minimal distances in the air, chosen for Polish conditions are presented and given in the form convenient for design practice. They are based on the IEC standard concerning the co-ordination of insulation, so they assure a security for the insulation. They are complete when compared with up-to-date used requirements of the PBUE (Regulation concerning Electric Equipment Construction), fully rational and in many cases more advantageous also.
Electric Power Networks and Ecology
Energetyka 2004, No. 3, p. 160, 6 figs
Described are actions undertaken in the Torur) Distribution Company in order to minimise an influence of overhead power lines and transformer substation on the environment.

Complex Oil Service - the Most Effective Tool Aiding Machines and Equipment Maintenance
Energetyka 2004, No. 3, p. 162
A complex oil service means a system of technical - organisational actions assuring optimal conditions for machine and equipment lubrication at as low as possible costs of these actions. The oil service is an inseparable part of the system of machine and equipment maintaining oriented for the optimal reliability and enabling to avoid serious failures.

Fifty Years of Activity and Development of the Institute of Power Engineering
Energetyka 2004, No. 3, p. 165
(Bulletin of the Instytut Energetyki p. 1), 11 figs, 1 refs
The Ministry Council erected the Institute of Power Engineering on 2nd November 1953. An objective of the Institute is an activity in the field of investigations and development for the needs of the Polish power industry and entities working for the power sector. In the paper the up-to-date activity of the Institute is recapitulated, the most important achievements are given and the directions of its development are traced.

Operational and Ecological Assessment of Oil Power Burners of Various Design
Energetyka 2004, No. 3, p. 179, 8 figs, 11 refs
Emission of gaseous toxic substances has been defined for known ignition burners (of various design) in power units of great output. Investigations were conducted at variable calorific effect of the burners for optimal operation parameters of the burners, i.e. for minimum of soot, NOx and CO emission and at stabile burner operation. High emission of toxic substances from ignition burners of some types during the boiler start-up is proved. A necessity of the elaboration of emission standards for the start-up phase of the power boilers of great output should be considered.
