Overheating in Steam Boilers- In many industries, steam boilers are essential for processing activities. Plant managers adhere to several principles and procedures to guarantee that the boiler system runs well. Problems with boilers like corrosion, carryover, scaling, overheating in Steam Boilers, and so on are frequently unavoidable and must be addressed as soon as they are discovered.
However, in the case of boiler concerns such as overheating, prevention is preferable to treatment. Boiler overheating is a major boiler problem that can cause severe damage to the process plant and the operating people by placing them in danger of explosion. Although sophisticated boilers are outfitted with safety fittings to guarantee that the component is locked before the boiler overheats, it is advisable to be aware of boiler overheating and its symptoms to prevent it.
What is Boiler Overheating?
The breakdown of the safety device causes Overheating in Steam Boilers. When hot water carried to the central heating system cannot circulate, steam boilers overheat. A pump failure or an obstruction generally causes the Overheating in Steam Boilers. In addition, the breakdown of safety controls that regulate the temperature, pressure, gas, and water supply also causes the Overheating in Steam Boilers. In extreme situations, it may result in a condition known as a “runaway boiler,” which is dangerous to both the plant and the operating crew.
As the Overheating in Steam Boilers takes place, the interior components of the boiler are put under tremendous strain. It results in irreversible damage or, in extreme situations, a boiler explosion. In addition, when the boiler overheats, the components may melt and emit hazardous fumes into the environment. Nowadays, sophisticated steam boilers with automated control lock the units to avoid overheating and display an error message to warn plant management.
Causes of Boiler Overheating:
If the Overheating in Steam Boilers is not noticed quickly, it can cause significant harm to the environment and humans. Some of the most prevalent causes of boiler overheating are as follows:
- Limescale Build-up
- Blockage in the system
- Faulty pump
- Faulty thermistor
Limescale Build-up:
Limescale buildup on the heat exchangers obstructs water movement, causing the boiler to overheat. A heat exchanger aims to heat the water before circulating it for the combustion process. Limescale buildup is sometimes known as kittling because it makes a whistle sound like a kettle.
Blockage in the system:
Strange noises coming from the system suggest a blockage and Overheating in Steam Boilers. Another indicator of a clog in the boiler system is a radiator not heating adequately. It is often cleaned using a power flush method, which removes limescale, rust, and other contaminants to allow for the continuous flow of hot water.
Faulty pump:
The pump’s function is to circulate water in the steam boiler system. If the pump fails to work, hot water does not exit the steam boiler system, it causes Overheating in Steam Boilers. An engineer repairs the pumps, but they generally need to be replaced.
Faulty thermistor:
The thermistor is something that monitors the temperature of the water to determine if it has to be raised or lowered to meet demand. When the thermistor fails, the water temperature rises to dangerous levels. As a result, the boiler overheats.
Prevention for Boiler Overheating:
It is better to prevent boilers from overheating than to restore the damage. Overheating of boilers can be avoided by doing the following:
- It is installing a magnetic filter to capture dirt and rust in the heating system before it accumulates and causes a blockage. The accumulation of debris is one of the most prevalent causes of boiler problems that should be avoided.
- Installing a scale reducer reduces the production of limescale in hard water. Reduced limescale guarantees that the steam boiler system is free of water flow impediments that might lead to boiler overheating.
- Do not send cool water to the steam boiler when Overheating in Steam Boilers is taking place. It causes the boiler to flash into steam when it is supplied to the heated components of the steam boiler, resulting in a massive and quick rise in pressure. It can cause a boiler explosion or component failure.
- Avoid continual gas flow in the steam boiler because it creates a quick increase in temperature and pressure, leading to a runaway boiler.
- Reparation of steam boilers by an inexperienced engineer causes issues such as wiring errors, manual opening of gas valves, which results in a constant flow of gas, removing pressure relief valves while repairing boiler leakage, and failure to replace them, which prevents the boiler system from experiencing excess pressure. As a result, the boiler becomes overheated.
