Cím:Atmospheric spreading model for ammonia released from the poultry house / Tamás János, Gorliczay Edit, Borbély János
Megjegyzések:In this report a model calculation is presented for demonstrates the atmospheric dispersion of ammonia generated in a poultry house. Broiler breeding facilities work with high density of population as estimated 17 birds per square meter, thus the exhausted air contains significant amount of pollutants. Released dusts are minimal in the earl stage of the 42 days long breeding process, however, their amount increase exponentially, particularly in the last two weeks period. The major pollutant that must be release are as follows: fine particular matter, carbon dioxide generated by animal breath, and by older type of heating equipments, ammonia that is generated due to decomposition of manure, and in lower amount hydrogen sulphide and methane. The poultry houses are considered as point rather than diffuse sources. Concentration of pollutants is kept at a low level, which is required for the animal health, thus conditions are met with correct settings of the ventilation system (Kovács, 2000). The Bátortrade Ltd. (Nyírbátor, HU) installed heat exchanger equipments for saving energy related to ventilation. Thus, to avoid the return of air pollutant once had been released. ALOHA software has been used for spreading model calculations.
