PROCESS EQUIPMENT UPDATE
work well with all materials though. Te high peak force will penetrate completely through many materials only leaving a hole and not removing any build-up. A pusher type cannon blast literally
shoves the material out of the way. Tis can often be accomplished with a lower peak force, but using a larger volume of air with each blast. As long as the blast force exceeds the cohesive force bonding the build-up together or to the surface, the blast will remove the build-up. In addition, the blast time is longer, allowing it to penetrate further. Te larger volume of air delivers more mass, creating more energy to affect the material. Traditional air cannons from all manufacturers consist of a single air receiver tank with a firing/piston assembly to control the blast of compressed air. Te firing assembly may be externally attached to the tank, or more recently, internal to the tank. Either way, the air cannon has always been mounted to a nozzle or pipe that had been installed in the location where material build-up needed to be removed. Traditional air cannons needing to be mounted directly to the blast nozzle have always presented problems for the plant. Te air cannon is mounted very close to the process resulting in extreme heat and material from the process impacting the cannon. Tese are the major contributors to any company’s air cannons failing. Mounting the cannon this close to extreme heat makes it very difficult,

if even possible, to perform any maintenance duties to keep the cannon operating. And the nozzles and cannons are often mounted very high on a silo or structure. Performing maintenance on these cannons requires expensive scaffolding. Quite often no work is done to keep these cannons working. It is also very difficult for the plant to determine if these cannons are even functioning. Many applications require mounting
numerous air cannons close together, one for each nozzle. Tis restricts or prohibits the ability of plant personnel to perform
other required duties in this area. If more cannons are needed in the future it is very difficult to add any in these situations. Tese and other limitations have been accepted for many years. Te new Multiplier, or Super Cannon, minimises or eliminates these standard air cannon drawbacks. IGS can apply one single air cannon to a Multiplier system that replaces multiple single traditional air cannons offering many benefits over traditional air cannon installation. Remote mounting of traditional air cannons has long been discouraged by air cannon companies. Te thinking was the air cannon blast would lose its effectiveness over a length of pipe connecting to the nozzle. IGS has overcome this antiquated way of thinking by creating greater force and using a larger volume of air which maintain the blast power even through lengthy pipe runs. Tis combined with innovative nozzle technology and application experience have proven that mounting the air cannon in accessible locations is not only possible, but is the way air cannons will be applied in the future.
