Boiler Safety | Chemical Factory, Garment Factory, Noodle Factory Boiler Explosion, Caused Thinking

January 14, 2022

Boiler explosions that have occurred frequently in recent days have to sound the alarm for our boiler people. Boilers are general-purpose equipment used in our daily life and industrial production. The safe operation of boilers is particularly important, otherwise it will cause great harm, of which boiler explosion is one of the biggest hazards.

①At the end of December, a boiler at a manufacturing plant operated by Canton Laboratories in the Indian state of Gujarat exploded, killing 4 people and injuring 11 others.

The company manufactures fine and specialty chemicals for a range of industries, from pharmaceuticals to electronics and photography.

② On January 11, a boiler in a garment factory in Chittagong exploded, and seven workers were injured by the explosion. No major damage was caused as the factory authorities brought the fire under immediate control.


③ On January 9, a boiler in a food processing factory in the Muzaffarpur district of Bihar exploded, killing at least 7 people and injuring 11 others.


The factory was established in the Bella II industrial zone about four years ago to produce noodles and sweets. The boiler runs for a long time.


Boiler explosion  are scary. We must turn grief into strength, practice the purpose of safe production from bit by bit, and do a good job in every step of boiler safe production. Only in this way can you ensure that your production will not be affected and your life will not be threatened.


In order to prevent boiler explosion accidents, EPCB specifically summarizes the causes of boiler explosions and related preventive measures, hoping to help everyone eliminate potential safety hazards from the root cause.


There are three necessary conditions for a boiler explosion, namely:

(1) Sufficient amount of combustibles and oxygen;

(2) The mixture of combustibles and gas has reached the deflagration concentration;

(3) Sufficient ignition energy (open flame) exists.


Boiler Explosion Main Causes:


1. Unqualified boiler quality

When buying a boiler, if you only consider the price of the boiler and ignore the structure and details of the product, the quality of the boiler will not meet the standard, and the boiler with unqualified quality may operate normally in a short time. It will cause safety accidents such as boiler explosion.


2. Improper installation of boiler

In order to save costs, installing or modifying the boiler without permission will cause great damage to the boiler system, and it is very easy to cause boiler explosion. The installation of the boiler requires professional installation workers, and the boiler should be inspected by professional departments after the installation is completed, and it can be put into use until it is qualified, otherwise it will cause great safety hazards.


3. Improper use of boiler

During the operation of the boiler, the operator's misjudgment and misoperation, such as: air-burning and over-burning, etc., will cause damage to the boiler, destroy the boiler structure, and cause the boiler to explode.


4. The boiler lacks regular maintenance

If there is a lack of regular maintenance of the boiler.

①If the boiler blowdown is not timely, the quality of the boiler water will deteriorate, which will lead to scaling of the boiler and cause great damage to the boiler structure;

②Irregular dedusting of the smoke pipe will cause too much dust in the smoke pipe, which will make the smoke pipe heat unevenly;

③If the boiler accessories are not checked and replaced in time, it will cause inaccurate monitoring of the boiler operation and cause the boiler to operate incorrectly.

These can easily lead to boiler explosion.


Boiler Explosion Prevent Measures


1. Buy a brand boiler with guaranteed quality.

Regular brand boilers will have strict requirements on boiler raw materials, boiler structure design, production process and factory inspection, etc., so that the boiler can operate safely and stably.

2. Ensure the normal operation of the boiler and improve the professionalism of the stoker workers.

The safe operation of boilers is inseparable from professional stoker workers. No matter what kind of boiler, only the correct operation of the boiler can ensure safe and stable operation. Enterprises must require staff to have professional stoker certificates when hiring stoker workers.

3. Do a good job in monitoring the safety data of the boiler.

Excessive pressure of the boiler is a common cause of boiler explosion, and the pressure gauge is an important instrument valve to display the pressure of the boiler. If the pressure of the boiler exceeds the rated pressure of the boiler itself during operation, the pressure gauge will fail, and the safety valve will not be able to release the pressure, which will cause the boiler to explode.

4. It is forbidden to modify the boiler structure without permission.

If it is really necessary to adjust the boiler due to business adjustment, be sure to find a professional engineer. From the perspective of safety, it is better to buy a new boiler for the transformation of the boiler, because the cost of the purchase is much lower than the cost of the accident caused by the transformation.

5. Regularly inspect and maintain the boiler.

Regular maintenance of boilers includes boiler water quality testing, boiler blowdown, replacement of boiler accessories, and regular dust purging. 

① Regular water quality monitoring and sewage treatment of boilers can ensure the quality of boiler water and reduce the damage to boilers caused by boiler scaling;

② Regularly detect and replace boiler accessories, which can effectively monitor the operation of the boiler and avoid misjudgment and misoperation of the boiler.



Boilers are widely used in the industry, and the safe operation of boilers is related to the safety of each industry. No matter what industry you belong to, through the above content, I believe you have a comprehensive understanding of boiler explosions, understand boiler failures and take corresponding measures actively Prevention, your boiler can be used more safely and lastingly.

If you encounter other problems during the use of the boiler, you can contact EPCB boiler at any time, and EPCB can provide you with corresponding support.
