Steam boilers are vital equipment for steam generation in the process and manufacturing industries. Therefore, it is critical to know when it is time to replace an industrial boiler system. However, it is usually observed that facility managers wait for a steam boiler to break down entirely before replacing the unit. However, upgrading the steam boiler process plants can save a significant amount of money annually while also benefiting from increased efficiency and improved steam production when the boiler operates. Rakhoh Boilers being a trusted name as a boiler manufacturer in India has listed down some of the important signs that indicate the replacement of the steam boiler system.
Outdated Boiler System:
First and foremost, it is important to consider the lifespan of the steam boiler. If the boiler is older than 10-15 years, it is ideal to start looking for a replacement. It is true even if the boiler does not display any major faults. As the technology has advanced significantly in recent years, the old models are incapable of comparing with the efficiency levels, safety features, and smart control options of the latest steam boilers.
If there are occurrences of any type of boiler issues every week or topping up of the pressure, it indicates that things are about to change for the worst. The expenditure of the new parts, call-outs, and quick reparations can be spent much better on a replacement boiler that is efficient and reliable.
Boiler System Emits A Noise:
Sometimes, steam boilers are so outdated that the noises emitted from them are considered normal. On the contrary, the banging, gurgling, and kettling noises heard from the steam boiler indicate a boiler issue. If neglected, it can lead to severe damage in the process plant and breakdown over time.
A steam boiler functioning properly ensures complete combustion with a blue flame. But, if the boiler flame is yellow, it means that there is a risk of carbon monoxide emission, which is a serious issue. It is a hazardous, odorless, and colorless gas that can prove to be fatal if exposure levels are overly high. The symptoms of carbon monoxide poisoning consist of dizziness, nausea, headaches, and fatigue.
If there are any water leakages in the steam boiler system, it can result in significant damage to other steam boiler components. Therefore, it is important to contact an engineer as soon as possible before things escalate and become dangerous.
Replacement Parts Difficult to Find:
If process plants find it difficult to procure the parts of the steam boiler for replacement, it is to be concluded that the system is outdated. It is a quite clear warning sign that the boiler’s days are limited, and replacement of the boiler is the need of the hour.
High Stack Temperature:
If the steam boiler faces unusually high stack temperatures, it is an indication of unsafe conditions and poor heat transfer. It may be caused due to poor water management, poor combustion, or low water level.
Improper or insufficient airflow and fuel flow can lead to significantly noticeable pulsations and surges.
Reduction in Efficiency:
If the steam boiler system takes too long to operate or to generate steam, it showcases the inefficiency of the boiler system. In such situations, it is imperative to contact the boiler manufacturer for their expert guidance in replacing the system.
What is better– Replacement or Retrofitting?
Even if the steam boiler displays no decline in condition or performance, operations managers need to consider whether they should opt for a boiler replacement or retrofit. A boiler retrofit can offer the advantage of increasing the efficiency between 10% and 12%. On the other hand, a complete steam boiler replacement may offer even greater percentages depending on the boiler.
In either case, a retrofit boiler or a complete boiler replacement significantly reduces the future expenses of the process plant. Considering the average boiler consumes up to four times its original value in energy costs per year, it is easy to see how efficiency savings can quickly add up.
