Based upon our study findings, your plant challenges, fuel selection and operating targets, LKAB Minerals can offer a choice of solutions; Duraheat A, Duraheat MS, Duraheat AMS and Duraheat MSS.
Duraheat A
• Good absorption properties to capture potassium which could help protect pipework & boiler walls from corrosion , particularly if using variable fuel(s).
• Proven with the recycling model offered by LKAB & Richmond Recycling, improving sustainability & reducing onward purchase price of bed media.
Duraheat MS
• Potentially offers the longest fluidisation time of the Duraheat product range.
• High melting point, so gives stability in bed. (1450-1500oC)
• Cost effective in initial purchase price pmt.
• Strong material availability.
• Can be used in conjunction with alumina clay fuel additives to improve alkali capture properties to assist in protecting the asset.
Duraheat AMS
• Combined benefits of extended fluidisation time if compared to 100% Alumina Silicate, and improved absorption of ash contaminants when compared with 100% Magnesium Iron Silicate.
• As a blended product this reduces reliability on one material source.
• Cost effective when compared with 100% Alumina Silicate.
• Tailored particle size for optimum “bubbling” in boiler bed.
Duraheat MSS
• A cost effective Duraheat product at point of purchase, based on cost per metric tonne compared to 100% Alumina Silicate.
• Extended fluidisation time over 100% silica sand, assisting to reduce asset downtime and a reduction in volumes required.
• Tailored particle size for optimum “bubbling” in boiler bed.
