Introduction
Keppel Seghers' ZEROFUELTM is an advanced fluidised bed technology designed for the efficient and environmentally friendly disposal of biosolids. It ensures maximal weight reduction and complete inertisation of solid residues with minimal emissions.

Principle
The fluidised bed concept is recognized as the best available technology for sludge combustion. Keppel Seghers has optimized this concept by enhancing furnace design and air injection systems.

Application
ZEROFUELTM is applicable to various waste types, including municipal sludge, paper sludge, oily sludge, and more. It can be integrated with or without energy recovery systems and can include pre-drying or complete drying systems. Notable installations include a 9-tonne capacity facility in Ponderay, USA, and a 5.4-tonne capacity facility in Copenhagen, Denmark.

Process Overview
The ZEROFUELTM system features a turbulent fluidised bed with a proprietary air distribution system for stable fluidisation. It ensures optimal temperature control and complete combustion, resulting in low CO and NOx emissions. The system operates at low excess oxygen levels, beneficial for low calorific waste combustion.

Features

• No auxiliary fuel required
• Minimal flue gas flow
• Low process emissions
• Complete destruction of organic compounds
• Low operating cost
• High reliability

Conclusion
Keppel Seghers' ZEROFUELTM technology offers a reliable and economical solution for sludge treatment, meeting stringent environmental regulations and ensuring efficient waste management.
