The article presents results of gasification of the synthetically mixed sample of waste in a 30 kVA transferred DC plasma reactor with a hollow graphite electrode. The subject of the research is a sample of waste consisting of components normally found in a municipal waste. The experimental test of waste gasification with a high level of organic fraction was implemented due to the verification of previously mentioned technology application also in the area of waste disposal at the current construction design of the reactor. Gasification took place in the inert atmosphere at the average temperature of 1578 °C. The goal of the experiment was the verification of possible synthesis gas production applicable in the energetic applications and focus of the possible usage of the energetic potential of, up to now not often used, secondary energy sources such as wastes.

Abstract:The present article describes the diagnostics of a compressor that is compressing a mixture of H 2 and N 2 on the basis of the results that were obtained by operational measurements of the flow rates and temperatures at selected compressor sites, as well as of the acoustic pressure levels during the full loading thereof. The obtained data were subsequently used to determine the limit conditions of the compressor operations in terms of the cooling capacity. A thermodynamic analysis of the compression of the H 2 /N 2 gas mixture was carried out with subsequent heat and energy flow calculation and the determination of the minimum cooling water flow rate that is required to ensure the continuous compressor operations.
