Does Effluent Treatment eat into your Distillerys Profit ? And you wish to get freedom from the cumbersome Effluent Treatment Process.
We at CBL make distilleries a zero discharge installation by burning Slop / Venasse as a fuel in boiler.
In this process we burn the concentrated distillery waste directly into the boiler. The effluent from distillery is taken to a concentrating unit and concentrated to 55 to 60% solids, either by RO or by evaporation system and then fired into a specially designed incineration boiler along with 35-40% support fuel like coal, rice husk, bagasse..
This consists of a specially designed boiler where the concentrated slop is sprayed from a height into the furnace in such a way that the slop gets dried and burns effectively in the large volumetric furnace. The boiler has special features to handle the high Potash present in slop.

ADVANTAGES OF INCINERATION
This system is highly economical as the entire steam required for distillery & evaporator is generated at high pressure and passed through turbine before using for the process and evaporator, hence produces power as bi- product. The support fuel requirement is about 35-40% only as the major fuel is effluent.
Since bio mass is being used as fuel in this process, it is approved by UNFCCC under CDM project for carbon credit.
Great contribution in the field of Water pollution control as there is no effluent discharge at all.
Great contribution in the field of ground water retention. As the recovered water from the concentration unit can be reused in distillery after a minor treatment. Thus the water requirement of distillery is reduced drastically.
In our patented design we also use external super heater allowing us to design these kind of boilers up to 67 Kg/Cm² pressure at 490°C temperature for higher turbine power output.
Huge saving in investment on land for setting up distillery as construction of digester for effluent treatment and press mud conditioning is not required.
Using a high pressure boiler with suitable back pressure turbine generates much more power than plants requirement which can be exported as surplus.
In bio methanation system about 25% carbon energy is consumed by bacteria, which is saved in this system thus it becomes energy efficient.
The ash of this boiler contains high Potash. Thus it is used directly as fertilizer.
