The paper discusses the feasibility of installing renewable energy generation technologies on sea-going transport, taking into account the additional weight and power consumption. This study in based on the power management of a 26,198 tonne commercial chemical tanker. The management system would aim at reducing the number of generators as well as the power required from burning fossil fuels. After a process of elimination of potential technologies based on feasibility of the project and shipboard application, the work is focused towards photovoltaic and wind energy generation in combination with fossil fueled engines and Li-ion battery storage covering the higher energy density needs, and the intermittent nature of renewables. The network architecture is optimized in order to have the highest efficiency, and reduced system weight. The results show that successful management of the system can lead to reduction in generator requirement, and energy despite the weight of extra installations of photovoltaic and wind energy generation systems. By reducing the number of generators and allowing each remaining one to operate near their maximum power, the specific fuel consumption is improved, the efficiency is increased, resulting in significant fuel and cost saving, along with the mass of fuel to be carried on-board.

Przedstawiono rolę gazów ochraniających jeziorko ciekłego metalu w procesie spawania łukowego przed dostępem powietrza atmosferycznego. Podano klasyfikację gazów osłonowych stosowanych do spawania i cięcia wg normy PN-EN 439 obowiązującej w Polsce od 1999 r. Zastosowanie nowych gatunków stali (np. duplex) spowodowało konieczność rozszerzenia normy o dodatkowe podgrupy z nowym składem gazu. Zmiany te ujmuje norma EN-ISO 14175:2008. Omówiono główne mieszanki gazowe oferowane przez Air Products, a znane pod marką handlową "Linx".

It has been presented the role of gases protecting the molten metal puddle against atmospheric air in arc welding processes. The classification of shielding gases used in welding and cutting technologies according to PN-EN 439 being in force in Poland since 1999 has been given. The application of new steels grades (for instance duplex steels) caused the necessity to enlarge this standard by including in it additional sub-groups with new gas compositions. These changes are mentioned in the EN-ISO 14175:2008 standard. The main gas mixtures offered by the Air Products company, distributed under the trade mark "Linx", have been described.

The combustion of solid fuels is a major economic source of energy but it has the drawback that it can cause environmental pollution. Various means of controlling the adverse emissions have developed over the years and further developments are currently being made and some aspects of those developments are outlined here. Particular attention has been given to the cofiring of coal and biomass in the last few years. These topics have been of considerable interest to the Institute and to the University of Leeds over a number of years, and in particular in relation to CONBIOT. In this paper some of the work undertaken at Leeds is reviewed.

Spalanie paliw stałych jest najważniejszym gospodarczym źródłem energii, lecz może być również powodem skażenia środowiska. Różne sposoby regulacji szkodliwych emisji były rozwijane przez lata. W pracy przedstawiono przewidywane kierunki ograniczania emisji. Szczególną uwagę poświęcono współspalaniu węgla i biomasy na przestrzeni kilku ostatnich lat. Tymi zagadnieniami przez wiele lat zajmował się Uniwersytet w Leeds, w szczególności w powiązaniu z Centrum Doskonałości CONB1OT. Omówiono wybrane prace badawcze realizowane w tym Uniwersytecie.
