Explosive Deslagging / Cleaning
Blasting Solutions, Inc (BSI) is a company designed specifically to provide explosive deslagging services for the power boiler industry. From hoppers, main furnace, verticals, back pass, economizer, wind ducts, bag houses or precipitators, scrubbers, and/or settling tanks, BSI uses explosives to clean these vessels to a man-safe condition. BSI is a woman-owned business.
Experienced explosive deslagging professionals
BSI is committed to providing the best trained, best equipped, safest explosives professionals in the business. BSI’s supervisors are the most experienced in the explosive deslagging field and our technicians go through a rigorous training program to ensure a safe and productive environment on the job.
As the rest of the explosive deslagging companies have gone toward being commodity based, BSI decided service to our customers needs to be a core value. Safety first, customer service, integrity, value, initiative, innovative and compliant are the core values which make our handshake good.
- Explosive placement – BSI plays an active role in research and development of tools which will protect the vessels we conduct explosive operations in
- Quick-Clip – a patented system which enables our personnel to securely attach explosives to vertical and horizontal tubing, ensuring explosives remain in position during the cleaning process. They can also be used to keep explosives away from contact with tube surface
- Stand off – provides positive separation of explosive and tubes, increases visual acuity for explosive placement, does not significantly increase job time, and may in fact reduce the job time
On-line deslagging services
On-line deslagging presents some specific concerns. Because of the additional risks associated with using explosives and the reaction stainless tubing has with water, we have looked for and developed a tool which is capable of providing on-line deslagging services, without the use of explosives or water.
BSI utilizes explosives primarily to deslag boilers using coal, wood or fuel oil. Typical applications include the removal of slag, clinkers, pendant build-up, and webbing between the tubes (gas passages), furnace throat plugs, and other hard deposits normally requiring manual labor to remove. Many of these deposits overhang work areas and pose severe hazards to personnel entering the furnace during an outage. Build-up in gas passages also impedes safe repair and decreases operating efficiency.
Explosive deslagging for safe cleaning and repair
Our service uses the controlled detonation of explosives, prior to personnel entry, to remove these hazards and allow for the safe completion of cleaning and repair operations. BSI’s trained professionals first examine your system to determine precisely what types of charges are needed for the best results. We use a non-electric system to eliminate the possibility of accidental detonation by static electricity or radio interference.
Explosive removal of build-up in back pass areas eliminates or minimizes the need for traditional water cleaning and the associated cementing of run-off material. Both hard and soft materials are removed along with the webbing that can build up between the tubes.
After explosive cleaning is completed, the resulting debris is usually small enough to be removed from the ash hoppers by the plant crusher equipment.
Efficient explosive deslagging
Compared to conventional removal, explosive deslagging is up to three times faster. Additionally, BSI emphasizes performance-driven rates instead of hourly rates to facilitate a ‘get in, get the job done safely, and get out’ attitude within the company. These facts result in significant time savings and reduced costs due to lost generation for plants during both emergency and scheduled outages.
Once the process is completed, heat transfer and control are greatly increased resulting in less downtime, increased productivity and reduction in maintenance costs throughout the year.
