Knowing the quantities of substances emitted into the atmosphere is a necessary and fundamental reference in the development of environmental protection policies and in the monitoring of a phenomena such as acid rain, air quality degradation, greenhouse effect and climate change, ozone depletion, deterioration and affecting the appearance of buildings, exposure of the population and ecosystems to hazardous substances, etc.
Low combustion efficiency (especially for boilers with installed power under 1MW), the poor quality of the fuel used (high sulfur content, low calorific power, high content of impurities in fuels, etc.) and lack of pollutant substances restraint systems make that the low-power instalations to be considered the major sources of pollution. Contributions of small combustion plants to total emissions vary and depend on the type of pollutants and the geographical area.
Within the project, an interactive dialogue with ImA holders and stationary engines was carried out, the study team contributing significantly to the information-awareness process of ImA holders on specific issues concerning the recording and reporting of data relating to technical characteristics and the data to be reported for achieving the local emission inventories.
The working methodology included the identification of emission sources, the elaboration of procedures necessary to obtain data for the inventory of small combustion plants and static thermal engines by producing questionnaires for ImA inventory, collection, verification of data obtained, data quality assurance, processing and interpretation of collected data.
