Abstract

Generalization and analysis of experimental data show the increasing of the SO2 content in flue gases with the growth of steam load for all the types of oil shale boilers. The SO2 concentration can be presented in some approximation as a function of the boiler furnace heat liberation qv in the following form: SO2 - 0.0165 q(v). On the basis of created mathematical models a program complex has developed allowing to calculate the SO2 removal efficiency by oil shale components and additional sorbent based on CaO. Test calculations indicate that the role of different factors on the SO2 removal process (such as gas temperature, particles concentration, size distribution and structure, interaction time, place of installation of additional sorbent nozzles, etc.) may be evaluated. In the 42-74% range the calculated values of the SO2 removal efficiency agree satisfactorily with experimentally determined ones.
