The management of the residues resulted from waste thermal treatment is an integral part of waste management. Most part of this kind of residues ends in landfilling disposal. One of the major problems arise from landfilling is the contamination of the environment with harmful substances that can be transmitted by leaching. © 2013 IEEE.

Considering the load-voltage characteristics according to voltage in the power network nodes and the whole national power system (NPS) has a direct influence on the operating condition and, implicitly, on the conditions to optimize the level of active power losses in the power networks. The paper highlights the effect of considering the load-voltage characteristics within the power network nodes in choosing the voltage condition to reduce the active power losses in the power supply networks of the users, the opportunity of applying this method in optimizing the operating conditions of the power plants (both in design and operation).

Experimental analysis of pollution sources and pollution footprint study in the metropolitan area of Bucharest for four seasons is the goal of this work. The study is conducted for NOx and SO2 pollutants coming from power plants, the input data is obtained from automatic monitoring stations for air quality. The information stored in an Access database is processed based on the Gaussian model dispersion air quality OML (Local Operational Model). The programs developed allow the dispersion to obtain concentrations from each individual source and pollutant concentration in a certain geographical point.

In this article, the authors propose a comparative analysis of air quality in urban area of Timisoara before and after retrofitting of the local power plant, with the goal to identify the level of human discomfort. The air quality analysis was based on on line measurements consisting of legally attested equipment that was set up to monitor fine particulate matter, nitric oxides NO, NO2, carbon monoxide CO, sulphur dioxide SO2, and, as well as wind speed and direction. Emission data collected during 2 years, in 2012 and 2014 before and after retroritting, referring to maximum 24-hour concentrations and the occurrence of exceedances over the limit values are comparatively analyzed. The relative investigation presents the evolution for the concentration of the most important pollutants involved in the atmospheric pollution process. Finally, in addition to measures already achieved for retrofitting and declared effective by the comparative analysis, one also proposed supplementary pollutants control technologies on coal fired boilers in response to new requirements of air quality, as well state of art for the pollutant emissions.

This paper has as main objective to establish the influence of individual heating systems and centralized heating system on air quality in the urban area Timisoara. To have a view on the main factors of NOx pollution in the downtown Timisoara, authors made a simulation of the dispersion of nitrogen oxides released from power plants CET South and CET Center asing the program ISC3. View, this represents the state of art in this field. This is the first study conducted in this regard after the refurbishment of two power plants from Timisoara. To compare the two sources of heating, district heating and individual heating authors must determine the concentration of NOx produced by the two sources per Kwh. To study the impact of these pollution sources on the level of NOx authors have to take into account where the flue gas emission is located.
