4.5.1. Complex technology to reduce toxic gas emissions from coal-fired boilers of TPPs

V.R. Kotler, I.A. Ryzhiy, JSC “VTI”, Moscow, Russia

Coal combustion at thermal power plants and large industrial boilers usually results in a problem of ensuring the standards for permissible emissions in the atmosphere of three components: ash particles, sulfur dioxide (SO2) and nitrogen oxides (NOx). In the Russian Federation legislative limits of these emissions are based on sanitary standards for maximum permissible concentrations (MPCs) of the substances in the atmospheric boundary layer (1.5 m from the ground level). These rules (MPCs) are set for all pollutants, but for power engineering only maximum one-time concentrations (average for 20 minutes), given in Table 1, are of interest.

4.5.2. Complex environmental technologies introduction in power industry of the Russian Federation

М.P. Rogankov, Ecopolis ltd, Moscow, Russia

The survey contains information on technologies which can be applied to reduce harmful environmental impact of TPPs in complex. Recent activities of power companies in this field are analyzed as well as their plans in the future. An opinion on the necessity of creating the incentives and beneficial conditions for introduction of complex technologies in the framework of state decisions relating to transition of industries to the best available technologies is expressed.
