SHOCKSYSTEM™ -- Acoustic Horn vs. SHOCKSystem™

In comparing technologies, Pressure Profiles, Pressure Amplitude and Fracture Mechanics tests show the SHOCKSystem™ outperforms Acoustic Horns.

Acoustic Horn vs. SHOCKSystem™ Online Detonation Cleaning

Technologies Comparison

Comparative highlights between technologies
Online Detonation Cleaning™	Acoustic Cleaning
Ominidirectional-propagating blast wave	Ominidirectional-propagating acoustic wave
Single impulse	25-220 Hz frequency
175 dB Minimum	130-150 dB Maximum
10 pulses repeated every 8 hours per combustor (30 cycles per day)	10-second operation every 10 minutes per horn (144 cycles per day)
Successful in continuous-maintenance mode and remedial cleaning mode – established deposits are removed as well.	Used principally in continuous-maintenance mode – do not allow ash to accumulate or sinter.

The SHOCKSystem™ employs Pulse Detonation Technology The SHOCKSystem™ Detonation Based Online Boiler Cleaning Technology is NOT a "Turbocharged" Acoustic Horn.

Pressure Profile: Blast Wave vs. Acoustic Wave

Acoustic wave pressure profile


Pressure Profiles Show A blast wave from the SHOCKSystem™ is a discrete pressure discontinuity – fundamentally different from cyclic waves of acoustic horns.

One Strong Wave vs. Several Weak Waves
Fracture Mechanics
	Fracture mechanics suggests one strong blast is more effective than many small waves to fracture brittle deposits. For example, for an assumed exponent M=10, 1020 Cycles at 130 dB (0.01 PSI) produce same effect as 1 Cycle at 170 Db (1 PSI)
Fracture Mechanics Show: One blast wave from the SHOCKSystem™ is more powerful than an unrealistic number of Acoustic Cycles occurring in a single day.
