Landfill disposal is today`s most common management option used by ash generators in power plants. The cost of ash disposal continues to increase due to stringent environmental regulatory requirements. How to manage ash in a cost effective manner has become more important in promoting the sales and marketing of Atmospheric Circulating Fluidized Bed (ACFB) combustion technology. A cost-effective and environmentally acceptable ash management is essential to ensure the continued development of this technology. The chemical and physical characteristics of the by-product determine how the waste will react with its environment and with systems for handling, disposal and utilization of the material. Diverse utilization options have been identified for ACFB residues and the potential uses include: agricultural applications, structural fill, and acidic waste neutralization. Most of these applications have to meet specifications by following certain test methods. As part of this ongoing ash management study, a data bank was established containing the chemical and physical characteristics of ash from Foster Wheeler commercial boilers located throughout the US and abroad. Based on laboratory investigation of ash characteristics, utilization options for different commercial boilers were concluded. It was demonstrated that all ACFB ash can be utilized for one or more of the purposes noted above.
