Methods and apparatus for use in monitoring and/or controlling kraft chemical recovery furnaces.

摘要

A system for monitoring, controlling, and optimizing the operation of a kraft chemical recovery furnace includes a mechanism (90) for determining carryover particle counts (82), bed profile information (84), and temperature information (84) of a smelt bed (30) over a major portion of the bed. The locations and temperatures of high and low temperature spots on the bed can be determined. This information may be displayed, such as on a common screen (116), for use by the furnace operator in controlling the furnace. Trending and history of bed performance in relationship to these characteristics may be tracked for use in diagnosing furnace operating problems and in adjusting parameters of the furnace to enhance furnace performance. <IMAGE>
