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.
PP Boilers’ Spent Wash Fired Boilers are engineered to handle the unique challenges of burning high-moisture, high-impurity slop. Key features include:
- Single-Drum Water Tube Design: Ensures efficient heat transfer and steam generation.
- Multi-Pass Furnace: Prevents fouling and slagging caused by impurities like chlorine, sulfur, and potassium oxides.
- Fuel Flexibility: Can operate on 100% slop or a blend with supporting fuels like rice husk, coal, or biomass.
- Emission Control: Integrated with ESPs, scrubbers, or bag filters to meet environmental standards.
These boilers are ideal for distilleries aiming to reduce waste disposal costs and achieve sustainable operations.

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
