Spent Wash Fired Boilers

Spent Wash Fired Boilers

An effective spent wash incineration solution helping distilleries meet steam, captive power, and economical ZLD (zero liquid discharge) compliance

Submit your enquiry

TBWES spent wash-fired boilers convert distillery spent wash into valuable energy, reducing waste and operating costs effectively.

Engineered to handle varying spent wash concentrations, ensuring reliable and sustainable operations for both large-scale operations and micro distilleries (under 30 KLPD). Their robust, efficient three-pass design maximises thermal performance, making them an ideal solution to meet zero liquid discharge (ZLD) norms. Beyond environmental compliance, these boilers offer significant commercial value; the potash-rich fly ash generated provides an additional revenue stream.
