About Slop Fired Boiler
Gyantosh's Slop Fired Boilers give distilleries a proven route to Zero Liquid Discharge by incinerating concentrated spent wash (slop / vinasse) to generate steam and power. Instead of treating spent wash as a disposal problem, the boiler recovers its calorific value — solving the distillery's most difficult effluent challenge while producing useful energy. GyanTosh is a pioneer in slop-fired boiler technology with over two decades of experience.
Concentrated slop from the evaporation plant is fired through specialised slop guns (including German slop-gun technology) in combination with a support fuel such as bagasse, rice husk, or coal. Careful furnace design, corrosion- and slagging-resistant heat transfer surfaces, and precise combustion control handle the high potassium and organic content of spent wash, which is notoriously fouling and corrosive.
Every slop fired boiler is designed and manufactured in compliance with IBR 1950 and IS 2825 using certified boiler-quality pressure parts. Fully automatic operation regulates slop and support-fuel firing to maintain stable steam parameters despite variation in slop concentration.
Available in capacities from 20 to 100 TPH, working pressures up to 87 kg/cm², and steam temperatures up to 515°C, GyanTosh slop fired boilers enable distilleries to achieve Zero Effluent Liquid Discharge (ZELD) while meeting captive power and process steam needs.

Slop Fired Boiler Specification
Fuels Used (Slop + Support Fuel)
Combustion Technology
Specialised slop guns (including German technology) atomise and fire concentrated spent wash into the furnace for stable, controlled incineration.
Bagasse, rice husk, or coal is co-fired to stabilise combustion and maintain furnace temperature as slop concentration varies.
Furnace geometry, soot blowing, and material selection manage the high-potassium, slagging, and corrosive nature of spent-wash combustion.
Slop and support-fuel rates are automatically regulated to hold steam pressure and temperature steady despite variation in slop quality.

Advantages of a Slop Fired Boiler
Incinerating concentrated spent wash lets distilleries achieve Zero Effluent Liquid Discharge — solving their most difficult environmental compliance challenge.
The calorific value of spent wash is recovered as steam and power, converting a costly disposal liability into a useful energy asset.
GyanTosh has pioneered slop-fired boiler technology over two decades, with the engineering know-how this demanding application requires.
German slop-gun technology ensures reliable atomisation and firing of concentrated slop for stable combustion.
Using in-house spent wash and by-product bagasse dramatically reduces or eliminates purchased fuel cost for captive steam and power.
Enables regulatory compliance with effluent norms while supporting a circular, sustainable distillery operation.
