Learn about current boiler exhaust gases
There is a lot of information related to the boiler that we need to pay attention to learn, and grasp clearly and in detail. In particular, learning about boiler exhaust gases is useful information to capture. From that necessary knowledge, determining how to handle appropriately will be much more accurate and appropriate. That’s the way to minimize the impact of boiler exhaust on the environment and people.
Normally, at production plants when using boilers, coal and FO oil are the main raw materials used as fuel. Besides, a few factories choose charcoal to serve production activities. From different raw materials used, the exhaust gas released into the environment is also completely different. In which, the main types of emissions are:
- Dust
- SO2
- CO
- NO
- SO3…
These are the main emissions from industrial boilers in production activities and they have the potential to cause negative, direct impacts on the environment. Therefore, how to be able to effectively handle and minimize the impact from boiler exhaust is important to be done, in any factory.
Harm of boiler exhaust gas
In general, the emissions generated from the boiler have a negative impact on the environment and on human health. For each specific type of emissions, its harmful effects also have certain differences. In particular, the exhaust gases that often appear in the boiler bring many negative effects such as:
- For SO2 gas is known to be excitable, and at the same time very soluble. Therefore, it can easily react with the respiratory organs of humans as well as animals. The disorder of protein metabolism can completely be caused by the impact of SO2 emissions.
- CO emissions from boilers are very dangerous, can directly affect human life in case we inhale too much. Reducing the amount of oxygen in the blood, damage to the nervous system, can completely lead to death is what we have to face when faced with CO emissions.
- Dust from boilers has the potential to cause negative effects on the human respiratory system. Diseases such as rhinitis, bronchitis, pharyngitis, etc. can be caused by the impact of boiler dust.
- Nox emissions when released into the atmosphere are likely to have an impact on people that we do not anticipate. When exposed after a certain time in the air, the concentration of NO2 can be 15-20 parts per million higher, which makes the lungs, heart, or liver of humans suffer severe effects.
Boiler exhaust gas treatment steps:
Use an exhaust filter bag
When using a boiler for production activities, it contributes to significantly improving work productivity. This makes it easier to improve profitability. However, when the use of boilers can lead to many inconveniences, especially the amount of emissions released into the environment is quite large, how can it be solved well and thoroughly treated to help efficient production? but avoid unwanted effects.
In the stages to treat boiler flue gas in production, the first step is the use of air filter bags. The toxic and harmful emissions will be filtered through quality Cyclon equipment. It is known as an air filter bag that effectively filters out exhaust gases and dust. This is considered the first step to help pre-filter the exhaust gases and dust that may be released into the environment. Before moving on to other stages, this is the first step that needs to be done.
When using the standard Cyclon air filter bag to filter the exhaust gas from the boiler, it ensures that the following processes are conducted most smoothly and efficiently. Thereby, minimizing the impact of emissions on the environment and on humans is easy and effective as expected.
Perform the coarse dust separation step
After the use of the filter bag is completed and carried out according to the standards, the next step to do is to separate the coarse dust. How to treat boiler exhaust gas to get high efficiency and get the desired results, learning the steps and following the correct process is a must. Only then can the treatment achieve high results, provide maximum protection for the environment, avoid possible negative effects and make the treatment of exhaust gases unresponsive. most thought.
Coarse dust removal is a process that helps to remove small dust particles. The separation of coarse dust uses centrifugal exhaust fans so that everything is carried out accurately, conveniently and effectively. The use of a centrifugal exhaust fan system when impacted helps coarse dust particles swirl, from which they are thrown and broken into smaller particles. These dust particles comply with inertia and fall.
This process is made simple and easy but absolutely necessary and irreplaceable. Good removal of dust particles will reduce the harmful impact on the environment, giving people better results. In particular, for this process to take place smoothly, the use of suitable centrifugal fans, meeting new quality standards, brings about the expected high results.
From the importance, from the meaning of this step in the process of treating boiler exhaust gas, finding out information, being able to be proactive in all situations is an issue that we need to pay special attention to. It is the full implementation that helps to keep the treatment clean, avoiding the negative impact from the boiler exhaust to the maximum extent.
Absorption tower
The use of the absorption method in the treatment of boiler flue gas is the third and final step that we need to take. After filtering through the above two steps, at this time, the filtered air and dust particles will pass through a fully equipped and completed absorption tower. In the absorption tower, the use of suitable and specialized chemicals will help clean and safe air filtration before it follows the chimney and is released to the outside environment.
In a normal absorption tower, two processes take place. Specifically, the dust and residue are separated and at the same time recovered into the hard-to-treat area of the factory. Here, dust and residue will be stored and treated periodically, with the most appropriate method. Meanwhile, in the parallel process, the exhaust gas when reaching the standard, ensuring the necessary cleanliness will go through the pipeline and exit directly to the outside.
When two methods, two processes are carried out at the same time, it ensures that boiler flue gas treatment is carried out efficiently, accurately and with the greatest benefit, ideal results. At this time, it is easier to remove harmful gases, providing the ability to protect the fresh environment, for the good health of each person.
With a simple process, the steps are not too complicated, this is the ideal way to treat boiler exhaust gas, so it is trusted by factories and production facilities to apply. Through that, it becomes easier to protect the environment, life and health of each person. When each manufacturing plant needs a boiler for its work, it should be equipped with appropriate exhaust gas treatment methods and applied according to standards, which will help reduce the pressure on the environment much better.
Moreover, having a complete boiler exhaust gas treatment system is a standard and prerequisite condition for the plant to come into operation. Therefore, choosing the right solution with high application efficiency will make the boiler safe, high value, and beneficial as expected.
