BORESCOPE INSPECTION
DS Power offers advanced technology for borescope inspections of horizontal and vertical flow HRSG tubes. We identify with precision and detail the type and extent of external fouling accumulated on the tube surfaces, providing a complete and reliable mapping that helps define the ideal procedures for HRSG cleaning.
DS Power offers Borescope Inspection services using advanced technology and specialized tools to inspect the pipe rows in depth of each HRSG heat exchanger, without causing damage. We capture images and videos in high definition, allowing precise identification of the type and extent of externalfouling on HRSG tubes.
DS Power’s frequent applications include:
- HRSG cleaning planning: Detailed assessment of the cleanliness of the tubes in each HRSG exchanger, identifying the type and severity of fouling, in order to recommend the appropriate cleaning procedure.
- Performance Analysis: Detailed evaluation for HRSG system performance purposes, identifying inefficiencies related to fouling, heat losses and pressure drops.
- Quality Audit for Cleaning Services: Independent supervision of cleaning services provided by third parties, evaluating the effectiveness of the methodologies applied before and after cleaning, guaranteeing continuous improvement in the performance of the HRSG boiler.
- Inspections for Assembly Validation and Commissioning: Validation of turbine assembly, commissioning and upgrades, ensuring efficient integration with HRSG and optimizing system performance.
- Compliance with Standards and Technical Codes: DS Power ‘s borescope inspection services strictly adhere to ASME standards, guaranteeing the quality and safety of inspections and the integrity of HRSG systems.
Plant O&M benefits
IDENTIFIES TYPE OF FOULING
Borescope inspection provides detailed information on the nature and extent of fouling, such as iron oxide, sulphur, clay, ammonia or thermal insulation.
EVALUATION OF THE SCALE OF FOULING
Fouling can be classified into different levels of severity, making it possible to identify and prioritize heat exchangers that require immediate cleaning to restore thermal efficiency and minimize performance losses.
RECOMMENDS PROPER PROCEDURE FOR CLEANING HRSG
Based on the concrete data from the detailed inspection of fouling, it is possible to select the most suitable cleaning methods, guaranteeing the effective removal of up to 90% of deposits.
REDUCES OPERATION & MAINTENANCE (O&M) COSTS
It allows precise deadlines to be set, reducing investment costs for the cleaning service. It also improves thermal performance and extends the useful life of the HRSG.
