The desulphurizing and dedusting methods using condensation and wastewater in this paper may not only raise the desulphurizing and dedusting effect, reduce the operating cost but also recover a part of heat energy. It is an effective economical method in the desulphidation and dust alleviation of middle and small sized coal fired boilers. The desulphurizing, dedusting and energy saving of middle and small sized coal fired boilers has something to do with the technological operating condition and the structural parameter of the whole system. The paper researched the influence of the technological condition and the structural parameter of the desulphurizing installation on the desulphurizing and dedusting efficiency, energy recovery and equipment resistance. It provided basic data for design and operation of practical desulphrizing installation. Figs 8, table 1 and refs 6.
