Fluidized bed combustion technology of oily sludge.

Cfd Analysis of Circulating Fluidized Bed Combustion

In this paper computational analysis of circulating fluidized bed combustion using the fluent software is analysed. This work is concerned about gas–solid two-phase mixtures flowing upwards through the fast beds. The procedures studied are applicable to all types of fluidized-bed boilers. The type of information resulting from various ways of analyzing the pressure and temperature in fluidized ...

Studies on Ash Behavior during Co-Combustion Of Paper Sludge in Fluidized Bed Boilers

Combustion of Dry Sewage Sludge Particle in a Fluidized Bed Reactor

 This paper presents a mathematical model of the cylindrical particle combustion in a fluidized bed reactor. This particle is composed of sewage sludge. The model performs a mathematical description of the physical and chemical phenomena that occur during particle combustion. The uniform particle model without ash accumulation is proposed. Sewage sludge is considered composed of three fractio...

Fluidized Bed Disposal of Secondary Sludge High in Inorganic Salts

The authors have presented an excellent example of the total systems approach to overcoming a dif­ ficult waste disposal problem. They have presented useful guideline data for fluid bed incinerators which are increasingly being adopted for thermal destruc­ tion of difficult organic sludges. Although not of concern in the design described, the fluid bed incinerator has the special capability of ...

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...
