As evidenced by our works as well as a number of other researches, sewage sludge is a renewable biological fuel. But the sludge use is quite problematic due to its high humidity and ash content. To reduce the moisture of the initial mass of the sludge, it is recommended to add dry finely dispersed biomass (saw dust, chopped straw). To conduct the research, we selected the long-term storage sludge samples of Bortnichi Activate Sludge Plant of Kiev city and the fresh sludge of the Lvov city purification facilities to produce the granules of 6 mm in diameter. The gaseous conversion of the granules was completed in the two stages according to the «backward heat wave» technology. As it has been established, the coke ash residue accounting for 53–63 % of the output sinters at the temperature of above 700 °С. The research has identified the gaseous conversion parameters, the composition and the combustion heat of the fuel gas. The recommendations pertaining to use of the fuel gas and the coke ash residue have been designed. Accordingly, the research conducted hereunder has discovered the possibility of full and partial gaseous conversion of the sludge granules using the air blast. Bibl. 10, Fig. 5, Tab. 2.
