Spent Wash (Slop) Fired Boiler for Distillery

Spent Wash (Slop) Fired Boiler

PP Boilers specializes in providing state-of-the-art Spent wash-fired Water Tube Boiler to burn 100% slop into the boiler and keep industry on zero liquid discharge. The proposed boiler is a Single-Drum Water Tube Boiler with multi-pass furnace design significantly improve efficiency, reduce waste, and enhance sustainability. PPB has proposed both external/internal fired super heater designs. The boiler are capable of firing concentrated slop (55–60% solids) with auxiliary fuels like rice husk, coal, or biomass. The boiler incorporates a multi-pass furnace design to tackle high levels of corrosive and fouling impurities such as chlorine, sulfur, potassium, and sodium oxides. Equipped with high-pressure slop injection systems, advanced combustion zones, and integrated pollution control devices, these boilers provide sustainable steam generation while ensuring emission compliance and operational efficiency.

Salient Feature

Description: Pressure & Process Boilers introduce Spent Wash / Vinasse fired water Tube Boiler to Brun 100% Slop into the Boiler and Keep Industry on Zero liquid Discharge. The proposed boiler is a Single-Drum Water Tube Boiler with multi-pass furnace design. PPB proposed both external / internal fired super heater designs. The boiler is design on 75% spent wash / vinasse in combination with supporting fuels like RiceHusk / Coal / Biomass and the slop contain Chlorine, Sulphur, K 2 O and oxides of Sodium and magnesium keeping in view of impurities in fuel the boiler is designed to avoid Fouling/Slogging problems.

Technology: The concentrated slops with 55 to 60% solid contents are injected into the furnace with the help of high pressure pumps and special-designed spray nozzles. The slops burns completely in free board and it does not reaches bottom of furnace i.e. bed or top of grate. The flue gases then pass through multi-furnace zone and major ash particles are separated at furnace outlet. The flue gases then pass through evaporator/super heater section in case of internal super-heater they pass through Evaporators, Economizer, Air Pre Heater, and Cyclone Bag House / ESP. The system is equipped with number of customized soot blowers for on-line cleaning.

High-Pressure Slop Injection: Ensures complete combustion in the freeboard without bed deposition
Multipass Furnace: Specially designed TG and RG.
Pollution Control Systems: Integrated with specific designed ESPs, cyclones, and/or scrubbers for emission control
Automated Soot Blowers: On-line cleaning system to maintain performance and reduce downtime
Compliance: Meets CPCB and international emission standards.

Features

Multi-Pass Furnace Design: Prevents fouling and ensures complete combustion.
External/Internal Superheaters: Customizable for high-temperature steam requirements.
Automated Soot Blowers: Ensures continuous cleaning and optimal heat transfer.
High-Pressure Pumps & Spray Nozzles: Efficiently inject slop into the combustion chamber.
Pollution Control Systems: ESPs, cyclones, and scrubbers for emission compliance.

Applications

Distilleries: Steam generation for fermentation and distillation processes.
Molasses-Based Industries: Utilizes vinasse from sugar and ethanol production.
Chemical Plants: Waste valorization for energy recovery.
