Acoustic Profiling of Bottom Ash
Entech Design, of Denton TX, sells a Material Acoustic Profile System (MAPS), which uses sophisticated oceanographic sonar mapping equipment to provide two and three dimensional images of bottom ash levels in water filled hoopers. Plant personnel can observe the level and distribution of material in the hopper, enabling smarter ash handling schedules and giving advance warning of any problems. The system can by integrated with distributed control systems for automatic control of bottom ash conveying routines.

MAPS has been on the market since 1991, and is currently installed on 44 units (including a couple of UFTO utilities). Extensive information and references are available.

BinMinder is an offspring of MAPS that monitors liquid-material interfaces in a wide variety of applications, such as chemical production and waste water systems. Utility applications include flue gas desulfurization tanks, pyrite holding tanks, and bottom ash dewatering bins, where it can be used to reduce material carryover due to overfilling, along with other operational benefits.
