Title: An Experimental Study on the Pyrolysis and Combustion Properties of Sewage Sludge
Abstract: In this paper,thermal andalysis was used to study the pyrolysis and combustion properties of two samples of sewage sludge.The results showed there are three stages during the pyrolysis and combustion.The first stage is all due to dehydration.For the pyrolysis,The second one is as the result of organic compound decomposition,and for the combustion,the second one is as the result of organic compound decomposition and fixed carbon combustion.In the third stage,the inorganic matter decomposes for the combustion,and the remnant organic compound goes on decomposing as inorganic matter decomposing for the pyrolysis.The reaciton rates of pyrolysis are more than the reaction rates of combustion during the second stage as a whole.The pyrolysis and combustion of sewage sludge are exothermic reactions.
