This paper deals with the environmental aspects of combustor modification on Nuovo Pignone gas turbines. The mentioned company is engaged in the transport of natural gas to the Slovak Republic and further to other European markets. Legislation considering emissions is getting stricter every year. Original Nuovo Pignone gas turbines would not be able to meet the required emission limits for NOx and COr determined by legislation. Therefore, the company decided to modify seven gas turbines. Due to this reason, the combustion sections had to be replaced with a dry low emission system. These modifications were aimed at improvement of impacts of temperature on the emissions of NOx, since the NOx emissions are defined as thermal (there is an increase in emissions with the increase in temperature). Emissions were monitored continuously by an emission monitoring system (these data are continuously sent to the Office of Environment) and manually by a HORIBA PG-250 analyser. Gas delivery point is located in the flue pipeline, and data was processed by means of PC after reaching this point. The results lead us to conclusion that modification was an efficient and good solution in terms of economy, because this solution reduced emissions (from 300 mg·m−3 to 50 mg·m−3) and contributed to meeting of the stricter emission limits (from 370 mg·m−3 to 100 mg·m−3). Monitoring of the impacts of growing performance of equipment on emissions represents a possibility for further development of science in this field.

Use of means of technical diagnostics gains in today's period increasing importance in all areas of industrial activity. Due to the tightening of the limits, software and hardware solutions improving is the diagnosis of the building one of the most important area in manufacturing and non-manufacturing organizations. The aim of the article is to clarify the possibility of using diagnostic procedures in the form of georadar to monitoring of location and status of reinforcement in a ferroconcrete bearing wall. For measuring was used radar system Mala CX12 with accessoriesand based on selected aspects has been diagnosed the exact location and status of the construction reinforcement. The result of this monitoring is to detect variations in the position of reinforcement and recorded corrosive damage. We investigated the humidity of concrete wall through the diffusion of EM waves while the evident product of decrease of the diffusion speed was the increased moisture of structure.The main outcome is to propose corrective measures in the form of the concrete carrying wall remediation necessity, as indicated by the results of this monitoring. By early use of the diagnostic means in the form of monitoring using georadar, it is possible to prevent the economic and environmental impacts.
