Assessment of impact of combined heat on the environment of urbanized areas (case study of Ulan-Ude, Russia)

Combined heat and power plants (CHPP) are an important component of the energy balance in many countries. However, of all types of power plants, CHPPs have the largest impact on the environment. In recent years, the urban ecology has become one of the key indicators that determine the quality of lif...

Description
Summary:Combined heat and power plants (CHPP) are an important component of the energy balance in many countries. However, of all types of power plants, CHPPs have the largest impact on the environment. In recent years, the urban ecology has become one of the key indicators that determine the quality of life of city residents. The article evaluates the impact of the CHPPs in Ulan-Ude on the example of CHPP-1. The main sources of environmental pollution, and, accordingly, the zone of exposure of CHPP-1’ pollutants have been identified. Virtually the entire territory of the city of Ulan-Ude falls under this zone, but since northwestern winds prevail in this area, the north-western part of the city is most affected. Based on the results of a detailed dispersion calculation, we defined the following substances which should be monitored: nitrogen dioxide, sulfur dioxide, mineral oil, and inorganic dust (70-20% SiO 2 and coal dust). The concentration of these substances in the air is significant.
