Modeling the desulphurization process while coal combustion in fluid boilers

In the article are discussed the basic problems affecting flue gas desulphurisation produced in the fluidized bed boilers burning brown coal. There are compared the effects of temperature, residence time and flue gas composition in the fireplace, characteristic parameters and properties of limestone and dolomites, ratios of limestone and coal and cocombusted biomass and recirculation of by-products. The kinetics and thermodynamics of many reactions are represented here by mathematical and empirical relations.
