Taking oxygen out of a kiln is important for several reasons:
Overall, taking oxygen out of a kiln is an important step in many industrial processes to ensure that materials are processed efficiently and effectively, while minimizing negative impacts on the environment.
Nitrogen is often used to clear a kiln of oxygen for several reasons:
Inert Gas: Nitrogen is an inert gas, which means that it does not react with other materials. This makes it an ideal gas to use for displacing oxygen, as it will not react with the materials being processed or change their properties.
Non-Toxic and Inexpensive: Nitrogen is a non-toxic gas that is widely available and relatively inexpensive. This makes it an attractive option for use in industrial processes, as it is a safe and cost-effective gas to use.
High Purity: Nitrogen is typically available in high purity grades, which means that it is free from impurities that could contaminate the materials being processed. This is important in industries such as electronics or pharmaceuticals, where even trace amounts of impurities can have a significant impact on the final product.
Easy to Control: Nitrogen is easy to control, as it can be introduced into the kiln in a controlled manner, either through a valve or other mechanism. This allows for precise control over the amount of oxygen in the kiln and can help to ensure that the temperature is maintained at the appropriate level.
By using nitrogen to clear a kiln of oxygen, the risk of unwanted chemical reactions or changes to the materials being processed is minimized, while the temperature can be precisely controlled. This is particularly important in industries where the quality and consistency of the final product are critical, such as in the manufacture of electronic components or pharmaceuticals.
So how do we regulate Oxygen and Nitrogen levels?
How do we make sure that our clients aren't using more then they need to?
Both these questions make what we do at Therser UK invaluable, our test kilns at the heart of our innovation.
Therser UK is investing heavily into this technology. Controlling Oxygen levels will in turn reduce running costs for product manufacture. Also ensuring no contamination occurs in their firing cycle.
The oxygen analyser works by measuring the partial pressure of oxygen in the exhaust gas stream. It typically consists of a sensing element, which is usually made from zirconium oxide, and an electronic control unit (PLC). The sensing element is heated to a high temperature and exposed to the exhaust gas stream. As oxygen in the gas stream comes into contact with the sensing element, it reacts with the zirconium oxide, creating a voltage signal that is proportional to the oxygen concentration.
The PLC processes this voltage signal and converts it into a numerical value, which can be displayed on a monitor or used to control the combustion process in the kiln. By monitoring the oxygen concentration in the exhaust gas, the oxygen analyser can provide real-time feedback on the combustion process and enable operators to adjust the amount of fuel and air being supplied to the kiln to maintain optimal operating conditions.
The use of an oxygen analyser is important in industrial processes because it can help to improve efficiency, reduce emissions, and ensure that the final product meets quality standards. By providing accurate and reliable feedback on the combustion process, the oxygen analyser can help to optimize the use of fuel and reduce energy costs, while also minimizing emissions of pollutants such as nitrogen oxides and carbon monoxide.
It doesn't matter if your project is small or on a huge scale we can help. Our engineers can also retrofit existing kilns with new fibre linings to improve their efficiency and productivity. To discuss your requirements please call 01782 824453, or email sales@therseruk.com
