About
As rapid growth in bioenergy limits the availability of traditional wood-based fuel, the industry is seeing a sharp increase in the use of high-alkali feedstocks such as agricultural and domestic waste.
But burning high-alkali materials causes increased bed agglomeration, fouling and corrosion, resulting in more shutdowns and reduced overall boiler efficiency. It can also create higher levels of NOx emissions.
To combat these issues, the choice of boiler bed material is critical. Our range of specialist minerals enables the use of agricultural and domestic waste as an efficient alternative to wood-based feedstock, helping to improve heat transfer and temperature control whilst limiting or eliminating unwanted side effects.
