Failure reporting of complex refractory structures 1

[YungPlantEng]

My company has 6 quench towers in a very corrosive process. There's three different brick materials, 6 brick shapes, a fiberglass membrane, carbon steel shell etc.

Obviously when a blow out occurs its an easy failure to represent but how does one develop a common communication between sites to explain whether an inspection looked good or bad? "Mortar washout" and "cracked long bricks" don't exactly carry much weight and the only continuity for decision making on rebuilds is generational knowledge from seniors.

Did not understand. You should rewrite this in a simple manner.

YungPlantEng,

Do your co-workers understand your terminology? Chat with them and see if there are commonly recognized terms for everything. Every organization has jargon of some sort.

Maybe your inspection documents need a schematic or sketch along with the commonly used descriptions.
This would give each section a name and describe different common issues.
This would encourage a standard way of describing issues.

Whatever the problem is exactly, one of the most useful methods is comparison rating system. Take photos or impressions of these elements in their various stages of wear/failure and ensure everyone has those in hand when they perform the inspections.

Or do what most people consider obvious - send the same inspector(s) to inspect the quench towers when they come down for service.

Standardized Inspection Protocol:

Develop a comprehensive inspection protocol that offers clear, step-by-step instructions for conducting thorough assessments of quench towers. This protocol should encompass the equipment to be inspected, essential tools, and the recommended inspection frequency.

Inspection Checklist:

Create a detailed checklist that inspectors can use during their evaluations. This checklist should encompass all aspects of quench towers, including brick materials, shapes, membrane conditions, and shell integrity. Each component should be broken down into specific items to examine.

Grading System:

Implement a standardized grading or scoring system that enables inspectors to rate the condition of each component consistently. For instance, a numerical scale from 1 to 5 can be used, with 1 signifying excellent condition and 5 indicating severe damage or corrosion. This system streamlines the assessment process.

Photographic Documentation:

Mandate inspectors to capture photographs of critical areas or identified issues during inspections. Visual documentation is invaluable for conveying the actual condition and supporting decision-making.

Reporting Format:

Establish a uniform reporting format that includes a summary of findings, the inspection date, the inspector's identity, and a comprehensive breakdown of each component's condition. Utilize the grading system to categorize the severity of identified issues.

Standardized Terminology:

Develop a shared glossary or standard terminology that precisely defines quench tower components and associated issues. Ensuring uniform language usage guarantees accurate descriptions of conditions.

Training and Certification:

Offer training sessions to inspectors on the standardized inspection protocol, checklist, and grading system. Certification can be considered to verify the inspectors' qualifications for conducting assessments.

Centralized Data Repository:

Establish a centralized data repository or database to store inspection reports and accompanying photographs. Centralized data storage facilitates easy access to historical data and facilitates trend analysis.

Routine Review Meetings:

Conduct regular meetings involving inspectors, maintenance teams, and relevant stakeholders to review inspection findings. These meetings are essential for discussing maintenance and potential rebuild decisions based on the collected data.

Knowledge Preservation:

Institute a knowledge preservation program to capture the wealth of insights and experiences possessed by senior employees. Document their wisdom, anecdotes, and lessons learned over the years and make this invaluable resource accessible to the entire team.
