Is your thermal oil system https://8ruiyan.com/en/all-organic-heat-carrier-boilers/ struggling to heat up? Failure to reach the set temperature is a common but frustrating problem. It can slow down production and affect product quality.
The causes usually fall into a few key areas. Below is a breakdown of the most common reasons and where to look for solutions.
Main Culprits: The Six Most Common Cause Categories
1. Heater Capacity Issues
The Core Problem: Insufficient Power
The issue might be fundamental. Your heater may be undersized for the current process. The required heat load may have increased over time. Check if your heater’s power output (in kW) is sufficient.
2. Problems with the Thermal Oil
The Heart of the System: Oil Condition
The oil is the heart of your system. Its condition is critical.
- Degraded Oil: Over time, oil breaks down. It can form sludge and carbon deposits (coking). This sludge acts as an insulating layer inside the heater and pipes. This severely reduces heat transfer efficiency.
- Incorrect Oil Type: Oil with too high a viscosity (too thick) will not flow properly. The heater may overheat locally, but heat won’t circulate effectively.
- Low Oil Level: A low level in the expansion tank can lead to flow issues and pump cavitation. This disrupts the entire heating cycle.
3. Poor Circulation
The Circulation Problem: Restricted Flow
Efficient heat transfer depends on strong, consistent oil flow.
- Faulty Circulation Pump: The pump may be failing, running at low speed, or have a worn impeller.
- Blocked Filters/Strainers: Clogged filters are a common cause of restricted flow. They should be checked and cleaned regularly.
- Valve or Piping Issues: A valve might be accidentally closed. Pipes could be obstructed or incorrectly configured.
4. Air in the System
The Invisible Blockage: Trapped Air
Air is a poor conductor of heat. Trapped air or non-condensable gases in the system create pockets that block the flow of hot oil. This can prevent the system from reaching its target temperature.
5. Faulty Instrumentation
The False Reading: Sensor or Control Failure
Sometimes, the system is working, but the readings are wrong.
- Inaccurate Sensors: The temperature sensor or controller may be faulty or out of calibration.
- Stuck Control Valves: A valve meant to regulate flow or temperature might be stuck in one position.
6. Process-Side Changes
The External Factor: Increased Demand
The issue may not be with the thermal system itself.
Have there been changes in your process? For example:
- Running a higher volume of material.
- Feeding colder material into the system.
- A dirty heat exchanger on the product side.
Quick Action Checklist
- Check Basics: Verify oil level and listen to the circulation pump for unusual noise.
- Inspect Filters: Clean or replace blocked filters and strainers.
- Review Maintenance: Was any work done just before the problem started?
- Test Sensors: Calibrate or compare temperature readings with a separate thermometer.
- Analyze Oil: Send a sample for laboratory testing to check quality and degradation.
- Consult a Specialist: For persistent issues, contact your system manufacturer or a maintenance engineer.
Kesimpulan
Final Tip: Start your troubleshooting with the simplest possible causes. Often, the solution is straightforward. Regular maintenance and oil analysis are the best ways to prevent these problems.
