EPIC™ OFF-LINE HRSG CLEANING
The EPIC (Extraction Pressure Impulse Cleaner) is revolutionizing HRSG cleaning. This off-line cleaning technology uses safe, effective and directly targeted impulse cleaning energy to remove deposits deep within and throughout tube bundles. The patent-pending cleaning procedure that is employed systematically concentrates its affect just to the fouled tube sections, with no indiscriminate blasting impact to the surrounding area, nor mechanical fatigue to the tubes or superstructure.
This type of cleaning system has been used effectively nearly a decade for on-line boiler cleaning including HRSGs. IMPULSE® pressure waves are generated in a controlled, pulsed manner, safely within a 3-inch system chamber to direct cleaning waves into surfaces where debris has collected. EPIC utilizes pressure waves to create a high amplitude particle displacement to resonate and dislodge particulate deposits. This creates a very targeted, deep 360° cleaning so heat transfer efficiency can be restored.
- Targeted impulses create deep, penetrating + encompassing 360°cleaning
- No mechanical integrity damage to tubes or entire structure
- No mechanical tube stretching or spreading required
- Energy is directionally controlled through the tube bundle (i.e. no violent shock or indiscriminate blast impact to entire HRSG structure)
- No scaffolding required
- Reduced outage time compared to alternative methods
- Proven on-line cleaning technology for 10+ years supported by multiple US patents
Why EPIC over other methods?
Safe for Your Entire Unit
EPIC’s impulses are highly targeted through the tube bundle and do not cause any damage to the mechanical integrity of the tubes. Plus, there is no violent shock or indiscriminate blast impact to the HRSG structure. In addition, the tubes will never be stretched or spread.
No Pre-Cleaning Work
No scaffolding is required nor tube spreading, or other modifications are necessary to gain access for cleaning. Minimal site support resources are needed.
Reduced Cleaning Time
Utilizing the advanced EPIC technology, with remote positioning and activation of the IMPULSE cleaning equipment, results in reduced overall outage duration as well as confined space exposure compared to several other methods. The service is also complemented by the post-cleaning removal of the considerable dislodged debris by incorporating Thompson’s own vacuuming equipment and personnel, rather than orchestrating additional arrangements with yet another contractor for the turnkey HRSG cleaning project.
