Journal ArticleDOI
Thermochemical processing of sewage sludge to energy and fuel: Fundamentals, challenges and considerations
TL;DR: In this article, the options of converting sewage sludge to energy and fuel via three main thermochemical conversion processes namely pyrolysis, gasification and combustion are reviewed, and various alternative approaches deserving further consideration, such as the incorporation of pre-processing and co-utilization, are discussed.
Journal ArticleDOI
A review of technologies and performances of thermal treatment systems for energy recovery from waste
TL;DR: It emerged that the dominant type of thermal treatment is incineration associated to energy recovery in a steam cycle, and gasification with syngas use in internally fired devices, pyrolysis and plasma gasification is the mean to improve energy recovery.
Journal ArticleDOI
Utilization of urban sewage sludge: Chinese perspectives
TL;DR: This work states that Anaerobic digestion followed by land application is the preferable options due to low economic and energy costs and material reuse and the reuse of biosolids in all scenarios can be environmentally beneficial and cost-effective.
Journal ArticleDOI
Energy use and recovery strategies within wastewater treatment and sludge handling at pulp and paper mills.
TL;DR: An inclusive approach with focus on energy use and recovery in wastewater management, including wastewater treatment (WWT) and sludge handling, indicates that excess energy use in WWT processes counters the potential energy recovery in the sludge Handling systems.
Journal ArticleDOI
Co-gasification of wet sewage sludge and forestry waste in situ steam agent.
TL;DR: The thermogravimetric analysis showed that weight loss and the maximum weight loss rate of the sample increased with the increase in FW content and the gas yield decreased with the increasing WSS content.

Sewage sludge combustion
Joachim Werther,T. Ogada +1 more
TL;DR: In this article, a review of the current and future issues related to the combustion of sewage sludge is presented, and a number of technologies for thermal processing of sludge are discussed in three groups, i.e., mono-combustion, cocombustions and alternative processes.
Journal ArticleDOI
Ten residual biomass fuels for circulating fluidized-bed gasification
TL;DR: In this article, the ECN has successfully tested 10 different biomass residues in its 500 kW th circulating fluidized-bed gasification facility, including demolition wood (both pure and mixed with sewage sludge and paper sludge), verge grass, railroad ties, cacao shells and different woody fuels.
Journal ArticleDOI
Gasification of sewage sludge using a throated downdraft gasifier and uncertainty analysis
TL;DR: In this paper, it is suggested that the downdraft gasifier should be operated at 3.69-3.43% of the feed rate, at 2.28-2.84% of specific gasification rate and around 93.64-94.15%±1.92% of turndown ratio in order to avoid clinker formation at the throat of the gasifier because of high ash content of sludge.

Experimental investigation and modeling of gasification of sewage sludge in the circulating fluidized bed
I. Petersen,Joachim Werther +1 more
TL;DR: Experiments of sewage sludge gasification were performed in a circulating fluidized bed of pilot plant scale (15m height, 01m id) for the examination of the influence of the air ratio, gasification temperature, feeding height and fluidization velocity several screening tests were conducted to understand better the results from the screening experiments, axial profiles of the gas composition were measured.
