Abstract
In this work, the thermal behavior of rice husk, sewage sludge, and their blends during combustion processes was investigated by means of thermogravimetric analysis (TGA), and the slagging characteristics were studied through X-ray fluorescence (XRF) and melting temperature. The effects of the proportion of rice husk and sewage sludge blends on the combustion process, ignition and burnout characteristics were also studied. The blends had rice husk percentages of 30, 50, 70 and 100%. The results indicate that there are four main stages of the material burning processes: dehydration, volatile oxidation, and decomposition/oxidation. The reactivity of the blends improved with increasing amounts of rice husk and the results suggest synergistic interactions between rice husk and sewage sludge during the co-combustion process. All co-combustion ashes showed a lower slagging potential owing to their high amorphous SiO2 content. On the basis of combustion properties and slagging characteristics of ash, the ratio of sewage sludge in the blends should not exceed 30%.

Biomass has been used in industrial production activities as a source of renewable energy and a substitute for fossil fuels
Five types of rice husk-sewage sludge blends were prepared with increasing sewage sludge weight percentages of 0, 30, 50, 70 and 100%
The low heating value (LHV) is calculated by Equation (3) [23]
Summary
Biomass has been used in industrial production activities as a source of renewable energy and a substitute for fossil fuels. The use of this kind of renewable fuel for power production is governed by legal and international regulations, and its utilization as bio-fuel is a critical component of sustainable growth for most countries [1]. Among different types of biomass, rice husk is commonly used as bio-fuel for power plants owing to its low average heating value [3]. Sewage treatment plants generate solid wastes known as sewage sludge, which may contain toxic substances, including inorganic and organic compounds as well as pathogenic microorganisms [4]. The main problems in treatment of sludge for thermal utilization arise from the large volume and high moisture
