Bottom Ash Level Measurement for the Power Industry

Ash Tracker^TM

Ash Tracker is a product and Trademark of Entech Design, Inc.

For more than a decade, coal-fired power utility stations across the US have relied on our patented MAPS 20/20® imaging system for reliable bottom ash measurement and control.

These systems assist operators to –

Monitor bottom ash levels, distribution patterns and ash volume (Cu. Ft.)

Set alarms and control points to initiate conveying

Convey based on ash level rather than time

Maintain water level in the hopper

Confirm that hoppers are fully emptied

In response to customer demand for low cost solutions that can be applied in a broader range of ash collection systems, we are now introducing the next generation in this important measurement technology – Ash Tracker™.

Ash Tracker offers many of the same features of MAPS 20/20, but with these advantages:

Very low initial cost of investment and ongoing cost of ownership

Inexpensive, robust, fixed-point sensors – do away with the high cost and frequent maintenance of mechanical scanning sensors

Can be applied in a broader range of ash system design – including low profile tanks, submerged flight conveyors and step-bottom hoppers

Simple set up and operation

Enhanced measurement reliability with repeated signal sampling at fixed measurement locations

Ash Tracker utilizes strategically located fixed-point sensors for effective measurement at dramatically lower cost – reducing equipment costs by 60–70% compared to scanning systems. Budgetary pricing for a typical conventional bottom ash hopper collection system ranges from $7,500 to $22,500 (varies with the number of hopper sections).
