Equipment Inspections Services
A reliable source offering a wide range of services, LJUNGSTRÖM inspection and outage support means you can get everything you need to maintain your equipment in one place.
We offer a comprehensive range of technical services designed to evaluate, diagnose and maintain your equipment and ensure it is functioning optimally.
LJUNGSTRÖM and our authorized partners offer world-class inspections to ensure that your air preheater is functioning as efficiently as possible. Our expert field service engineers and technicians take a comprehensive approach, leaving no stone unturned in order to maximize your air preheater’s performance.
Our technical service specialists and engineers, along with our authorized partners, will carry out inspections of every area and component within your operation and provide a detailed report.
Inspections Can Include:
- Heating element basket review and recommendations
- Rotating component life assessment
- Condition assessment of sealing system and drive system
- Shaft position and bearing inspection
- Cleaning system efficiency evaluation
- Assessment of operating parameters and performance
Blueprinting increases efficiency by restoring your unit to original design specifications and will provide direct cost savings to your operation.
A comprehensive condition assessment survey is performed by our technical service engineers, with the results used to assist in the planning process and implementation of a phased program of recommended action items to increase the efficiency of the unit. As an example, there are multiple cases of 40-year-old air preheaters where the sealing systems have been Blueprinted, bringing leakage levels down from over 20% to less than 6%.
Other areas where Blueprinting has shown results include thermal performance due to rotor alignment, gap reduction and repairs.
With OASIS, we can help you understand how your air preheater fleet is performing.
During the in-service equipment walk-down, LJUNGSTROM service engineers assess the operation of the air preheater at its normal temperature and pressure levels. This process is significantly more comprehensive than the daily walk-down generally practiced by owner’s operations personnel. Readings and observations are documented and comments are provided for conditions, which are non-typical.
OASIS will assist in diagnosing critical air preheater issues while the unit is online and provide recommendations to resolve any operational issues that are detected during the assessment. A comprehensive assessment report with as-found conditions and future recommendations will follow the assessment to ensure you are prepared for your next scheduled outage.
Understand Health
And Performance
It’s a simple way of monitoring and observes trends to help you identify abnormal performance patterns from a single report.
Plan For Future
Maintenance
Predict the hours necessary to keep things running prior to a breakdown, balancing preventive and reactive service.
Assessment For
Previous Work
Assess the operation of your air preheater at its normal
temperature and pressure level.
Unit Walk-Down
- Assess the unit for knocks, abnormal rubs, and noises.
- This includes the drive assemblies and critical structural components that are visible during the inspection
Soot Blower Operational Assessment
- Witness the operation of the soot blower assembly so travel and dwell time can be witnessed and recorded
Duct & Expansion Joint Assessment
- Leak and hot-spot detection
Guide & Support Bearing Assessment
- Oil level, temperature, vibration, air leaks, oil analysis review
Operational Data Collection
- Collect operational data and provide the information to our performance group for review
The performance testing of rotary heat exchangers is a complex undertaking and we have the experience, knowledge and expertise to assist with all aspects of rotary heat exchanger performance testing, including the planning, test execution and detailed analysis of test data in accordance with globally approved standards such as PTC 4.3 (US), VDI (DE), and JIS (JP).
