A study on the chemical looping combustion of sewage sludge: The emission of NOx and its precursors
Chemical looping combustion (CLC) is a promising low-NOx combustion technology for sewage sludge disposal. Herein, the emissions of NOx and its precursors (NH3 and HCN) during the pyrolysis and CLC processes are investigated on a fixed bed reactor. In particular, the effects of reaction (gas) temperature, sludge ash accumulation, and reaction inter...

Multifunctional Additives for NOX Abatement in Fluidized Bed Biomass Combustion
Two major challenges in fluid bed combustion of biomass are increased NOX emissions and bed agglomeration. Different additives were employed to simultaneously reduce NOX emissions and bed agglomeration from the fluidized bed combustion of biomass. The base fuel was straw, and the additives included CaO, kaolin, MgCO3, coal fly ash, clay, (NH4)(2)Fe...

The mixtures of bio-oil derived from different biomass and coal/char as biofuels: Combustion characteristics
Bio-oil is produced as a promising fuel for improving the economics of biomass. However, bio-oil utilizations suffer from challenges due to its complex compositions. In this research three bio-oil samples (BSR, BPA and BFT) were blended with coal/char to prepare slurries as biofuels. The thermogravimetric analysis of combustion and ash compositions...

Physicochemical and thermal analysis of argan fruit residues (AFRs) as a new local biomass for bioenergy production
A detailed investigation of the physicochemical properties and thermal characteristics of argan fruit residues (AFRs) was carried out to identify their potential application as biofuels. This experimental study covered the four main by-products of argan fruit: argan pulp (AP), argan nut shell (ANS), argan oilcake (AOC) and argan deoiled cake (ADC)....
Optimal strategy for clean and efficient biomass combustion based on ash deposition tendency and kinetic analysis
Synergistic Characteristics and Capabilities of Co-hydrothermal Carbonization of Sewage Sludge/Lignite Mixtures
Co-hydrothermal carbonization (co-HTC) has been reported as a potential technology for enhancing fuel qualities and subsequent combustion behaviors of high-moisture raw biowastes or coals. For the purpose of real energy utilization, two low-fuel-quality materials, sewage sludge (SS, a biowaste) and lignite (LC, a coal), were employed to explore the...
