| EnergyTech: SHOCKSystem™ Reduces Tube Erosion
One of the concerns in operating coal-fired boilers, particular those that burn coal with high fouling tendencies, is how to effectively and efficiently clean ash deposits from heat exchanger surfaces. A pulse detonation system, such as the SHOCKSystem™ can significantly reduce or eliminate these problems.
