EnFloTech Innovative Technology Advancements
1. Company Introduction
Enflotech is a South African leader in coal and biomass mill upgrades, with a global presence in the power generation sector. The company offers patented solutions that guarantee at least a 20% improvement in mill performance. Enflotech has also been integral in several large-scale coal-to-biomass conversions, particularly in the UK. One of its innovations, the Desander, is designed to remove abrasive minerals and reduce inorganic sulphur, which helps lower SOx emissions and improve the sustainability of coal-fired power generation. Enflotech’s focus on clean coal and biomass energy positions it as a global leader in sustainable power generation technology.
2. Company Technology
2.1 Coal Beneficiation – The Desander
Low-quality coal poses several challenges, including excessive wear on mills, burners, and boiler tubes, increased ash production, and higher NOx and SOx emissions.
Enflotech’s Desander technology addresses these issues through a post-milling beneficiation process that removes high-density minerals like quartz and pyrites, reducing ash content and mill wear. The Desander helps to:
- Lower wear on mills, PF pipes, burners, and boilers
- Remove inorganic sulphur, reducing SOx emissions
- Reduce mill recirculating loads and improve throughput
2.2 High-Performance Rotating Throats (HPRT)
Enflotech excels in coal mill aerodynamics and has achieved global success with its HPRT technology, also known as port rings or vane wheels. This component enhances mill performance by improving the interface between primary air and pulverized coal particles.
Benefits include:
- Reduced system resistance for increased throughput
- Optimized particle rejection and reduced internal wear
- Elimination of particle roping and settling
- Reduced mill power consumption
The modular design of the HPRT allows it to fit existing mill footprints with a conversion time of just 56 hours. Enflotech guarantees a 10% improvement in mill performance and offers a 3-year guarantee.
2.3 Ultra-High Performance Static Classifiers (UHPSC)
Enflotech’s UHPSC technology enhances mill performance by achieving optimized primary and secondary classification, ensuring that the final product meets boiler specifications. The UHPSC design overcomes space limitations in existing mills, reducing system resistance and improving throughput. Key benefits include:
- Improved PF distribution and compliance with Low NOx emissions standards
- Reduced carbon in ash
- NFPA 85 compliance
The UHPSC is modular and can be installed with minimal modifications, with a conversion time of 70 hours. Enflotech guarantees a 10% performance improvement, a 10-year guarantee, and a 75% passing rate through a 75-micron mesh.
