Common Deaerator Problems and How to Find Corrective Measures

No matter the size and niche of your processing business, industrial boilers are among the essential equipment you need for continuous and successful productivity. Corrosion is inevitable and it’s also the leading factor in the failure of these boilers.

As a result, you need deaeration, a process where you remove gases, including oxygen and carbon, to limit rusting and malfunctions in your boiler system. Deaeration works by dissolving any present gas that could compromise the functionality of your boilers.

But still, because deaerators come in many models, let’s explore the common deaerator issues you need to keep in mind and how to find prompt corrective actions.

Poor Venting

There are about six possible causes your deaerator has poor venting problems. It could be because of incorrect thermometer readings, insufficient steam flow, inconsistent water ratio, and sometimes spray valve malfunctions. Or, the problem could be a result of heater flooding and an incorrectly installed inlet flow pipe.

As these problems happen, the deaerator vents fail, leading to poor venting problems. As a result, you see steam fumes coming out of the deaerator stacks. Over time, increased steam fumes cause deaerator leakage and lead to increased temperature levels in the boiler systems. But to keep your deaerator and boiler system reliable, start by monitoring the deaerator pressure and temperature levels.

Monitoring temperature and pressure begins with ensuring you have accurate gauges for checking these parameters in the deaerators. You can do this by using a digital or an analog deaerator thermometer. Plus, when checking the temperature, ensure the levels inside the deaerator matches with the equivalent saturated temperatures in the steam stable or with the surroundings.

Inconsistent Temperature Ranges Between the Steam and the Water

For your deaerator to perfectly support the boiler systems and anything else involving your processing business, the temperature differences between the steam and water shouldn’t be high.

Because when there is a high variation of temperature, the water inlet lines become prone to malfunctions which will automatically affect the performance of the deaerators. Monitor these temperature differences and keep them between two-degree variations.

Inaccurate Daerator Temperature Sensing

Unlike other deaerator problems, issues with inaccurate temperature sensing can occur within the deaerators or with the processing temperature sensing devices. When the problem results from the deaerators themselves, it could be coming from cracks.

Deaerator cracks occur when there is residual stress imposed during manufacturing and sometimes because of the effects of thermal dynamic shock and strains during the deaerator operations. But sometimes, deaerator cracks result from corrosion.

However, regardless of the causes of the cracks, they can lead to leakage within the boiler systems making it challenging for the temperature sensors to regulate and monitor the required temperature levels. And on the other hand, the problem could be because of malfunctions with the calibrated thermometers you use to monitor the constant temperature levels within the systems.

Inaccurate Steam Pressure Readings and Rumbling or Vibrating Noises

There should be accurate steam pressure readings for your boiler feedwater system or processing plant operations to operate efficiently. But when there is a problem, especially inaccurate steam pressure, the boiler system produces rumbling noises. The noise indicates corrosion inside the boilers and deaerators, affecting them from operating at their peak performance due to rust limiting their propelling abilities.

To prevent these problems, maintain your steam pressure readings within the levels your boiler system operates efficiently. This way, the deaeration process will perfectly run. And again, when you hear rumbling noises, check for corrosion and inspect the internals for clogging.

Finding a Quick Corrective Action for Deaerator Problems

After you identify problems with your boiler system or deaerators, avoid working with anyone advertising as deaerator professionals to prevent severe malfunctions. Instead, get help from a reliable and well-known deaerator firm. And one such firm is Jaygo Incorporated. Contact us today for prompt deaerator services.
