Technical control of air pollution in the iron and steel industry. Research Progress Report 30th June 1972.

The purpose of the series of research activities which are carried out with the support of the CEC is to gain basic knowledge about the kind and extent of those extraneous materials which on the one hand have an effect on the people working in an iron and steelworks and on the other hand have an effect on the immediate vicinity of such a plant. [...] For this reason the purpose of this investigation on the one hand is the systematic determi nation of emissions due to the operation of a coking plant in an iron and steelworks and on the other hand the investigation of the distribution and development of pollutants in the immediate vicinity of the plants.- The following emission sources are investigated: coal loading ramp coal miTing station coa [...] The change of capacitance depends on the dust content of the gas-dust mixture and on the grain-size distribution of the dusts. [...] One of these problems is the dependence of the dust oontent and the physical properties of the dust in the sinter waste gases on the application and operating conditions of the sinter plant. [...] The following investigations are carried out: Measurement of the dust content in the waste gas (before and after cleaning in the cyclone separators) - 31 - Measurement of the electrical resistance, the wetting properties and granular composition of the dust (with regard to the dust separation by electrical dust separating process) ffeasurement of the pollutants SO-, SO , Pb and Zn.
