Off-line Boiler and Vessel Cleaning
Evergreen North America offers two variations of the off-line cleaning technology. The first employs a telescopic probe which delivers the explosive cleaning charge to the target deposit while the technicians remain working from outside of the boiler or vessel. Multiple controlled detonations in grid patterns and at varying elevations quickly and safely allow for complete removal of deposits from boilers, kilns, silos, hoppers, process tanks and other large vessels. This cleaning method eliminates human exposure to falling debris, height, heat and other confined space risks.
The second off-line cleaning service utilizes linear explosives and is primarily used for cleaning fouled boiler tube sections such as the superheater, reheater, convection pass and economizer. During this service, Explosive Technicians suspend linear explosive charges within the fouled boiler tube gas lanes. When detonated, using a delay pattern formulated specifically for each job, energy waves are released and remove hard slag and ash deposits from the tube surfaces a full 360 degrees around. This cleaning service creates no by-product and can reduce cleaning time dramatically.
Emergency Response Mobilization
Evergreen North America Flight Services' pilots and aircraft are on standby 24/365 and ready to respond to your emergency explosive cleaning needs on short notice. Explosive Technicians and their equipment can rapidly fly to within close proximity (regional and municipal airports) of your location, minimizing mobilization time and ensuring quicker job start.
