Turbulent Fluidization. Turbulent regime has the following features:-. High solid hold-ups (typically 25-35 % by volume). Limited axial mixing of gas. Suitable for exothermic and fast reactions. Good gas-solid contact and hence, favors reactant conversion. high gas flow-rates operation and good for isothermal operation.

A sludge burner is placed in the incinerator to burn and dispose of sewage, sludge and waste oil. An auxiliary oil burner is also fitted to ignite the refuse. Automatic controls provided for the system secure the igniter when the refuse starts burning without the need of the igniter. Combustion air is supplied with the help of forced draught fan.
