Cleaning with dosed gas explosions

A lance with forced cooling is introduced into the boiler near the clogged area. At the end of the lance a balloon is inflated with an explosive gas mixture. The gas mixture is ignited via remote control ignition.

The explosion results in shock waves which cause the boiler-walls and -tubes to vibrate. The shock waves plus the vibrations will make the build ups / ashes come off the boiler surface.

SAFETY 

• Equipment is CE conform


• Safety measures and -procedures have strict rules for highest safety


• No risk for damaging of boiler tubes (even if explosion bags touches the tubes or walls!)


• No transportation, storage or use of explosives


• Gas mixture prepared just before explosion takes place


• Even if system should fail, process runs into safe conditions. System equipped with safety interlocking (fail safe)


• Optimal personal protection (Hard hat, goggles, dust mask, ear protection, safety shoes, face protection shield, fire proof working cloth)

APPLICATION REQUIREMENTS: 

• Openings (in boiler / vessel)
  to reach the areas to be cleaned


• Free space
  for lance introduction a minimum space in front of each opening is required


• Infrastructure on site
  pressurized air (4 to 8 bar), water (4 to 8 bar), power 240V (115V)

EXPERIENCE / RECOMMENDATIONS 

• Cleaning intervals:
  between 4 weeks and 6 month
  Basically determined by boiler design, waste composition and operating conditions.


• Remark:
  Boiler ashes in combination with humidity (from ambient air or steam) tend to form hard deposits.
  
  To avoiding these formations we do recommend to clean the boiler in hot conditions: during operation or during the shut-down of the plant.
