The Selection and Use of Fireside Additives on Industrial Boilers
MetadataShow full item record
As energy prices have escalated and fuel quality deteriorated, fuel chemicals have found increasing acceptance as tools for improving efficiency and reliability of combustion systems. Though application of fuel additives is not new, their use has been principally based on trial and error rather than a technical understanding of the complex reaction mechanisms. Consequently, they have, in the past, often been misapplied resulting in failure to resolve the problem addressed, undesirable side effects, and an undeserved but understandable reputation as 'snake oils'. Today, selection and use of fireside chemicals can be based on a growing understanding of the chemical reaction kinetics and particle transport in combustion systems. Combining this knowledge with practical experience allows the formulation and presentation in this paper of guidelines for use by the Power Plant Operator. They will guide him in choosing the type of fireside chemical to address a specific problem and in selecting the most cost efficient form and delivery system. Structuring the organization to provide the power plant operator with access to the specialized knowledge required and to facilitate objective evaluation of vendor claims are also discussed. Although treatment of both coal and oil fired systems are addressed, emphasis is on the former because developments in the technology need to be communicated and because of the increasing emphasis on conversion to coal.
