Diagram Fluidized Bed Incinerator

A fluidized bed is a physical phenomenon occurring when a quantity of a solid particulate substance usually present in a holding vessel is placed under appropriate conditions to cause a solid fluid mixture to behave as a fluid this is usually achieved by the introduction of pressurized fluid through the particulate medium.

Diagram fluidized bed incinerator. The principle of fluidization is the process where a granular material in a solid state is turned into a fluid like state by passing a fluid liquid or gas through it. A wte facility must be accommodated in a sufficient space for the incinerator the power unit installation and secondary facilities. Fluidized bed combustion fbc is a combustion technology used to burn solid fuels. A fluidized bed may be defined as the bed of solid particles behaving as a fluid it operates on the principal that when an evenly distributed air is passed upward through a finely divided bed of solid particles at low velocity the particles remain undisturbed but if the velocity of air flow is.

This results in the medium then having many properties and. Fluidization is a method of mixing fuel and air in a specific proportion for obtaining combustion. At bed operating temperature the sludge is continually fed to the fluid bed where it is dried and disintegrated in the sand layer. Fluidized bed combustors fbcs consist of a vertically oriented outer shell constructed of steel and lined with refractory.

Hankin is a leader in fluidized bed combustion of sludges generated from municipal and industrial wastewater treatment processes. Process mass flow diagram. Example of incineration plant with fluidized bed furnace. Co levels in flue gases were well below legislation limits with those of sewage sludge being higher due to the reduced reactor temperatures.

In order to reduce or eliminate the need for auxiliary fuel an air to gas heat exchanger recovers the heat from the off gas and preheats the fluidized air to around 1 300 f. 2 2 1 2 fluidized bed incinerators fluidized bed technology was first developed by the petroleum industry to be used for catalyst regeneration. Process operational data area. The hankin fbi system provides an environmentally sound and practical.

Hankin fluidized bed incinerator. In its most basic form fuel particles are suspended in a hot bubbling fluidity bed of ash and other particulate materials sand limestone etc through which jets of air are blown to provide the oxygen required for combustion or gasification.
