To remove oil from boiler water, you must use a specific off-line cleaning procedure with a heavy-duty cleaner.
Detailed Procedure for Oil Removal
Here's a breakdown of how to effectively remove oil deposits from boiler water, based on the provided information:
Off-Line Cleaning with Heavy Duty Cleaner
The most effective method for removing oil deposits from boilers, including L.P. steam generators, is to perform an off-line cleaning using a heavy-duty cleaner. This process involves the following steps:
- Prepare the Cleaning Solution: Mix a 2-5% solution of Heavy Duty Cleaner (Emulsifier) with water.
- Circulate the Solution: Circulate this cleaning solution through the boiler system.
- Time: Circulate for a period of time determined by the specific instructions provided by the cleaner manufacturer.
- Post Circulation: Drain the system of the cleaning solution.
- Rinse: Completely rinse the system with fresh water to remove any residual heavy-duty cleaner or loosened oil.
- Inspection: Inspect the boiler for any remaining oil deposits and repeat the procedure as necessary.
Important Considerations
- Off-Line Cleaning Only: It is crucial to note that Heavy Duty Cleaner (Emulsifier) must never be used as an on-line cleaner. All cleaning operations must be performed off-line.
- Proper Concentration: Using a 2-5% solution of the cleaner is necessary to achieve the required cleaning efficacy, according to the given reference information.
Why This Method Works
- Emulsification: Heavy Duty Cleaner (Emulsifier) works by emulsifying the oil deposits, breaking them down into smaller particles that can then be easily flushed away.
- Thorough Cleaning: Circulating the solution ensures that all affected parts of the boiler are thoroughly cleaned.
- Safety: By cleaning off-line, you avoid potential contamination or damage to the system during operation.
Summary
| Step | Description |
|---|---|
| 1. Solution Preparation | Create a 2-5% solution of Heavy Duty Cleaner (Emulsifier) in water. |
| 2. Circulation | Circulate the prepared solution through the boiler system off-line. |
| 3. Post Circulation | Drain the cleaning solution from the system. |
| 4. Rinsing | Rinse the system thoroughly with fresh water to remove any remaining cleaner and oil. |
| 5. Inspection | Inspect for any residual oil and repeat the process if needed. |
