Aurora Boiler Additives - Prevents Slagging, Fouling and bed agglomeration

Aurora Boiler Additives - Prevents Slagging and Fouling

Aurora is a patented combustion-enhancing additive specifically engineered to treat the fireside of furnace/boiler systems against the slagging, fouling, bed agglomeration, and corrosion that occurs as a result of burning fuels high in volatile alkalis such as agro-waste, biomass, coal, MSW, pellets, wood, and more.

In today’s unpredictable economy, increasingly restrictive emission regulations, and fluctuating fuel prices are driving energy producers to make operational changes such as burning non-design, opportunity fuels. While these opportunity fuels are lower cost, they can be difficult to burn. The slagging, fouling, and corrosion that results from burning these fuels can increase maintenance costs, safety risks, and decrease boiler availability.

Aurora significantly reduces deposits and can decrease maintenance costs to allow power plants to burn more lower quality, lower cost fuels.


  • Reduced maintenance costs
  • Increased boiler availability
  • Improved safety
  • Lower heat rates
  • Increased fuel flexibility

Suitable fuel mixes

  • Agro-waste
  • Biomass
  • Coal
  • Meat and bone meal
  • Municipal solid waste
  • Peat
  • Pellets
  • Pet coke
  • Poultry litter
  • Waste-to-energy
  • Wood / Wood waste


Site Survey

Imerys’ team of experienced engineers and combustion scientists can perform a thorough boiler survey and analysis of your fuels, bottom ash, fly ash and deposits. By working closely with your operational, fuels and maintenance staff, Imerys can recommend the optimal solution to solve your slagging, fouling and corrosion issues.

Capabilities include:

  • Meet with customer to identify needs
  • Survey the boiler operations
  • Perform a comprehensive analysis of fuels, ashes and deposits
  • Review the technical analysis & recommend a dosage regimen
  • Develop a process for on-site logistics and feeding system
  • Provide continuous customer service support

Analysis & Recommendations

Our team of experienced scientists can perform several analyses on the fuel, ash, and deposit samples collected from your boiler operations. These analyses may include proximate, mineral ash, and XRD of deposits/agglomerations depending on your boiler situation. Using these results, our scientists make a dosage recommendation for optimal performance. We can then work closely with your plant and operations managers to effectively apply the product.

The team has an in-depth knowledge of different fuels and boiler types. This knowledge allows us to provide problem solving
solutions for our customers.

Our principal areas of expertise include:

  • Combustion of a wide range of fuels in a variety of boiler types
  • Helping our customers with the changing of fuels and fuels blends
  • Regional application knowledge and technical support

Our team also has access to the Group’s main research centers and a number of regional laboratories across the globe which provides our customers with additional support.

Injection system

Our experienced team of scientists and engineers are able to recommend an application approach based on your fuel blend, boiler type, and overall system.

We offer a full range of custom formulation and technical and process support services to help you match the right mineral grade to your application requirement.
