Reasons for growing interest in toxic gas emission control include its potential for reducing noxious emissions. Uses of fuels as potential contributions to rural economic development reduce reliance on high quality fuels, as an additional demand centre for electricity commodities and as a way to urbanization.
Especially in waste incineration pro combustion emission control may cost higher prices such as 60-90/ton.Thebiowasteactivecarbonsoakedmagnesiaslurrymaycostlowersuchas3−5/ton. Fly ash or alkali wastes are produced in two different forms in size. One type of marble wastes is in lump size and easily be evaluated in civil industry and other may be evaluated as construction filling materials in fine size under 20 microns as which collected following solid-liquid separation thickeners. That waste in finer size may deteriorate environment near marble processing plants and water contamination in streams. Beneficiate from that finer bio-active carbon in toxic gas emission control during combustion can efficiently be made. However, fluidized combustion are carried out over 100 microns solid fuel combustion. In order to avoid this disturbing flow manner of that waste material, active carbon pellets were used in combustion chamber.
Fine marble wastes may also be evaluated as lime raw material without calcining for filling material in industrial sectors such as rubber, paper and animal food production. 40%,60% and 80% bio-waste and alkali containing active carbon pellets were used in our combustion experiments at 1-2mm sized pellets
