The report gives results of a systems analysis of the application of Limestone Injection Multistaged Burner (LIMB) technology to pulverized-coal boilers. It evaluates alternative limestone handling, preparation, and injection methods and boiler system impacts associated with LIMB applications. LIMB simultaneously reduces sulfur oxides (SOx) and nitrogen oxides (NOx) emissions from pulverized-coal boilers. It is based on using low-NOx combustion techniques combined with dry limestone injection into the furnace for simultaneous SOx control. The major aim of the study was to evaluate alternative concepts for application of the technology assess potential system problems related to its application, and identify engineering solutions to those problems. Further goals were to identify information needs related to technology application and recommend evaluations to acquire this information. Conceivably, all new boilers could be designed to handle any foreseeable impacts associated with LIMB; however, the practicality of LIMB as a retrofit technology depends on its compatibility with existing boiler systems. Sufficient information is not yet available to accurately gauge its applicability as a retrofit technology; however, this study identified potential system impacts, situations where the impacts will likely be minimized, and design or operating procedures for dealing with them.
