Spent-Wash Fired Boiler

Spent-wash/Spent-grain
Distilleries across the world are increasingly coming under pressure from government and society for the polluting effluents (spent wash/spent grain) from their core process. ‘Zero effluent discharge’ (ZED) norm for distilleries is already in place in a number of countries including India. Since existing disposal methods – biomethanisation and biocomposting – are unable to meet the ZED norms, distilleries are increasingly looking to an alternative solution of concentrating the spent wash/spent grain and then firing it in a specially designed boiler.
 
This fundamental shift in practice in the distillery sector has been facilitated by Thermax’s successful efforts to develop a commercial-scale boiler technology for firing spent wash/spent grain. The twin benefits of the boiler include:
 
(1) ability to dispose effluent discharge of distilleries in a safe and environmentally sound way (by meeting ZED norm) and
 
(2) steam generation for meeting the process steam and electricity requirements of distillery.
 
The first spent-wash fired boiler supplied by Thermax is undergoing commissioning trials at a distillery in Southern India, while four other units are under execution.
