Reducing the environmental impact on solid wastes

2019-5-4 · The use of three options for the reduction of the environmental impact of the solid sorbents used to control SO/sub 2/-emission in fluidized-bed coal combustion systems has been experimentally examined. The three options are: (1) the use of chemical reactivity enhancement agents, such

Plant for continuously regenerating foundry sand and

2002-6-4 · The plant for continuously regenerating foundry sand comprises a combustion chamber, in which a combustible gas is added to the sand, and a cooling chamber, in which the sand coming from the combustion chamber is cooled, both chambers being provided with systems for maintain the sand in a fluidized

Circulating fluidized bed Wikipedia

2019-6-6 · The circulating fluidized bed (CFB) is a developing technology for coal combustion to achieve lower emission of pollutants. By using this technology, up to 95% of pollutants[1] can be absorbed before being emitted to the atmosphere.

sand thermal regeneration plant with fluidized bed

US Patent for Process for the mechanical cleaning of . It is known in processes for the thermomechanical regeneration of foundry used sand to carry out a pneumatic-mechanical after-cleaning following a thermal regeneration stage, e.g. in a fluidized bed

Technology Overview: Circulating Fluidized-Bed

Tan silica pebbles are used as the material in the dense fluidized bed while fine speculite, limestone, and a rounded sand were originally tried as the entrained fluidized-bed material. Sand is now used initially in the entrained bed and is gradually replaced by accumulated spent limestone.

Coke Combustion Kinetics of Hot Carrier in Fluid Thermal

The coke combustion of hot carrier in fluid thermal conversion of oil sand was studied in a fixed bed microreactor,and the apparent kinetic equation and process conditions for

US4478572A Plant and method for regenerating

The invention relates to plant (1) and to a method for regenerating sand from foundry cores and moulds by calcination in a fluidized-bed furnace (2), the main characteristic of which lies in the fact that the fumes leaving the calcining furnace are used to heat a current of air which is then used, in its turn, to heat the sand to be treated at its inlet to the calcining furnace, and in that

sand thermal regeneration plant with fluidized bed

In fluidized bed combustion, rapid mixing ensures uniformity of temperature The main advantage of fluidized bed combustion system is that municipal waste, sewage plant sludge, biomass, agricultural waste and other high moisture fuels can be used for heat generation.
