AIR POLLUTANT EMISSIONS FROM COAL-FIRED POWER STATIONS.

Abstract

Two emission-measuring campaigns were carried out in coal-fired units of the Dutch Amer power station as a contribution to the Dutch National Coal Research Program (NOK). The results obtained during the campaign include data on (1) the composition of the fired coal (proximate and ultimate analyses; major, minor and trace elements), (2) the composition of flue gases (the gaseous elements and compounds O//2, CO, CO//2, NO, NO//x, C//xH//y, H//2O, HF, HCl, As, B, Br, Hg, Se an I, together with polycyclic aromatic hydrocarbons and particulate loadings) and (3) the particle-size distribution and composition of the emitted fly ash (major, minor and trace elements). Rough emission estimates for the future (until the year 2000) are made for a number of scenarios, based on an expected increase of 1% per year in electric-power consumption. The future coal demand and the resulting emissions of SO//2, NO//x and fly ash are compared with their equivalent values in the past (1965-1984). The range of trace elements in fly ash emitted during the last five years is analyzed.
