بيت /fly ash seperators
Fly ash is one of the most common waste materials created by burning of coal. It is composed of smaller particles, consisting mainly of aluminosilicate glass, mullite and quartz, which are collected by electrostatic separators (filter) of gaseous products arising from the combustion of coal.

Fly ash is an industrial byproduct which generated during the combustion of coal for energy production [1]. In China, the amount of about fly ash had increased to 600 million in 2017, only 70% of them were recycled and reutilized. They still occupied large amount area and caused severe dust pollution [2].

Fly ash chemically binds free lime and salts that can create efflorescence. The lower permeability of concrete with fly ash can help to hold efflorescenceproducing compounds inside the concrete. The ballbearing effect of fly ash in concrete creates a lubricating action when concrete is in its plastic state. This means: Increased workability.

Experimental studies were carried out on the separation of unburned carbon in fly ash powder using a special louver separator. The optimum operating conditions and the effects of the inlet flow rectifier, blade shape, and number of separators on both the separation performance and unburned carbon content were examined.
