IIT is delighted to introduce our latest fuel enrichment innovation for power station operators. Discover the multiple economic and environmental benefits of SilaniteTM, our fuel additive that requires NO changes to your boiler installation and can be retrofitted without downtime to the power station.
Silanite™ is a new, sustainable Fuel Enrichment system from International Innovative Technologies Ltd (IIT). It is an advanced fuel additive designed for coal-fired power stations requiring NO changes to the boiler installation and can be retrofitted without causing downtime. That means environmental and economic benefits that can be easily deployed by power station operators without having to make an up-front investment.
The IIT system will contribute to your power station’s bottom line from day one. The short period needed for implementation makes this system highly attractive for power station operators who are under immediate political pressure to demonstrate positive environmental action and economic capability.
IIT’s patented Fuel Enrichment technology is based on the addition of a multi-oxide additive to the coal feedstock used for steam and electricity generation. The additive, in a finely milled form with closely controlled particle size distribution, is mixed with the coal before it enters the pulverised fuel carrying lines.
In the burner zone the Silanite™ particles interact with the much coarser coal particles resulting in the cracking of the heavier hydrocarbons into lighter hydrocarbons and thus leading to a more complete combustion. The iron oxide in the fuel additive also acts as a catalyst for additional NOx reduction reactions, converting NOx into N2, which is a natural component of air.
A key component of the Silanite™ powder is an abundantly available by-product material that comprises a mixture of oxides of different elements, including transition metal oxides.
The Fuel Enrichment technology has been developed by IIT in partnership with combustion specialists from leading universities in the UK. For more information on these collaborations, please register here.
The Fuel Enrichment system at a typical injection level reduces NOx emissions with ca. 10%. This means that a power station with a current NOx emission level of 500mg/Nm3 will see a reduction of ca. 50mg/Nm3 before post-combustion de-NOx technologies are considered. Combustion tests have shown that the Fuel Enrichment technology is not only fully compatible with and complementary to SNCR (Selective Non-Catalytic Reduction), but also has other positive interactions with SNCR, basically acting as a catalyst for SNCR. The Fuel Enrichment system is the only NOx reducing system with additional benefits and no detrimental side effects.
The Fuel Enrichment system at a typical injection level reduces dust emissions with ca. 20%. This is thanks to the lower carbon-in-ash and lower resistivity of Silanite™-based fly ash.
