Gasification of Solid Waste--potential and Application of Co-current Moving Bed Gasifiers

نویسنده

  • M. J. GROENEVELD
چکیده

A review is given of gasification processes for solid fuels with special emphasis on waste gasification. Although the co-current moeing bed gasifier has not been under consideration for a long time, it offers interesting possibilitiesJor waste gasification. Some operational data are given. Two potential applications are discussed--gasification of agricultural waste (maize cobs) in the rural areas of Tanzania and municipal waste gasification.

Economic and Environmental Evaluation of Waste to Energy through Gasification; Case study: Tehran

In spite of the past few decades, gasification of waste is being used in the developed countries. Reducing the space for landfill sites, producing fuel from waste, as well as avoiding negative impacts of landfilling, are of advantages of gasification. The research was aimed at feasibility study of application of Tehran municipal solid waste (MSW) gasification in addition to understanding the wa...

GASIFICATION vs COMBUSTION OF WASTE/BIOMASS IN FLUIDIZED BED REACTORS

This paper presents a comparison of commercial fluidized bed gasifiers and combustors used to recover energy from municipal solid wastes and biomass. The work reported here is excerpted from four case studies prepared for the International Energy Agency’s Bioenergy Agreement, under Task 23 (Energy from Thermal Conversion of MSW and RDF, 1998-2000) and Task 36 (Energy from Integrated Solid Waste...

A general mathematical model for a moving bed gasifier

Abstract Cocurrent and countercurrent units are common configuration of biomass and coal gasifiers. Moving solid beds contact a flowing gas phase, usually air, steam or their mixtures. Batch and fluidized bed reactors, or drop tube gasifiers are also alternative units. The complexity of these systems relies in several aspects: the chemistry of the released species in the first devolatilization ...

Designing and Operating Reliable Gasifiers

Handling of bulk solids takes place in gasifiers either at the feed point or at the section of discharging waste and residues of the combustion and gasification. In large gasifiers, significant amounts of waste are expected to be produced, hence a proper gasifier design that allows an effective discharge of the waste from its bottom is essential for a smooth and reliable gasification. Poor gasi...
