How to Troubleshoot Abnormal Furnace Pressure in a High Temperature Vacuum Box Furnace

During operation, a high temperature vacuum box furnace may experience abnormal furnace pressure, seriously affecting normal operation. Symptoms of abnormal furnace pressure include unstable combustion, a smaller or larger flame, and increased noise. There are many causes, and this article describes some common solutions.

Causes of abnormal furnace pressure in a high temperature box furnace:

1. Fluctuations in fuel quality.

2. Excessive or low oxygen concentration.

3. Improper installation or wear of the airflow duct.

4. Excessive dust inside the furnace or an unclean working environment.

5. Loose or poorly sealed gas channels.

6. Dirty or clogged gas lines.

Common Solutions:

1. Check for leaks.

A common cause of abnormal furnace pressure in a high temperature vacuum box furnace is a leak. Carefully inspect all valves and pipes to ensure that gas is not leaking out of the furnace.

2. Clean the gas lines inside the furnace.

Clogged gas lines are a major cause of abnormal furnace pressure in high temperature vacuum box furnaces, so they require regular cleaning. Use compressed air and a vacuum cleaner to remove dust and debris.

3. Check the gas line pressure.

The flow rate and pressure of the furnace fuel are key indicators of proper operation of a high temperature vacuum box furnace. Insufficient gas line pressure can cause the furnace's hopper pump to malfunction, leading to unstable combustion. Check the gas line pressure to confirm if there is insufficient pressure.

4. Replace the gas line filter.

The gas line filter removes contaminants from the furnace and ensures stable combustion. Contaminated filters can lead to unstable combustion and even uncontrolled combustion. Therefore, regular replacement of the gas line filter is essential.

5. Check the gas line.

Loose or poorly sealed gas lines are also common causes of abnormal furnace pressure in high temperature  box furnaces. Therefore, it is necessary to regularly check the gas line seals and repair them promptly.

In the daily use of the high temperature box furnace, abnormal furnace pressure will have a great impact on the normal operation of the high temperature vacuum box furnace. For these possible problems, it is necessary to check them one by one to ensure the smooth progress and safety of the work.
