Abstract One of the main pollution types is air pollution, which has a significant impact on the surrounding environment and on living beings. Major source of air pollution is combustion processes. There are many flue gas treatment technologies around the world. In this paper a new, innovative flue gas treatment technology – fog unit – is introduced. The goal of the fog unit is to treat flue gases that are emitted from households. In the European Union, including Latvia, at the beginning of 2020, a directive will come into effect that will set limits for emissions and the effectiveness for incinerators in households. The main focus of this study was to determine the most optimal operating mode for the fog unit by changing different operating parameters: sprayed water temperature, sprayed water flowrate and types of nozzles (drop diameters). Results show that the most optimal operating mode in terms of flue gas treatment efficiency and recovered energy is at water temperature: 20 °C, sprayed water flowrate: 250 l/h and nozzle: MPL1.12 M. However, electrical consumption of water circulation pump leaves negative effect on this operating mode.

Flue Gas Treatment

AbstractEnvironmental pollution is one of the most important problems in present-day society. Governments and international organizations try to mitigate this problem by enforcing strict laws concerning the emission of certain pollutants. This process is especially rapidly applied concerning air pollution. In the past, the main focus was placed on the regulation of the energy sector and of land-based transportation emissions, as they produce the vast majority of pollutants. Today, the emphasis is shifted toward marine-based transportation, as it is anticipated that after the year 2020, the emission from sea-based sources (with respect to sulfur and nitrogen oxides) will exceed the land-based emission. One of the technologies that have been successfully implemented in industries to decrease the level of air pollution caused by NOx and SOx is electron beam flue gas treatment. This review shows the chemical principles of this method as well as the chemical engineering issues and its development and modifications to suit the changing needs of industries worldwide.

Particulate Matter Pollution

AbstractThe paper displays results of the questionnaire called “Particulate matter pollution in air”, which serves as a tool to determine level of public awareness of the health risks related to pollution from small capacity heating equipment in households. Barriers for installation of the innovative flue gas treatment technology called a fog unit in households and possible mechanisms to decrease or prevent these barriers were defined. The first part of the questionnaire included overall information about participants: age, gender, education level, place of residence, activities to protect the environment and motives behind performing these activities. The remaining questions were divided in four groups: “Environmental views”, “Knowledge on air pollution”, “Willingness to pay”, “Choice of flue gas treatment technologies”. The results of questionnaire correspond with raised problem situations. Over 80 % of respondents lack information on pollution and possible consequences deriving from it, and on potential solutions to prevent pollution. Residents of households are willing to pay for installation of flue gas treatment equipment (capital investments).
