Air preheater tubes are essential components in a unit’s air preheating system. They are responsible for transferring heat from the exhaust fumes or exhaust gases of the unit to the input air stream and using it to warm the air before it enters the combustion chamber of the unit. By preheating air in the air preheater, a unit is able to achieve higher efficiency, reduce fuel consumption and improve pollution levels.
Air preheater tubes come in several different materials, including materials like ceramics, stainless steel, cast iron and inconel. The material chosen determines the life span of air preheater tube. Generally, stainless steel is the preferred choice among industrial users due to its excellent thermal transfer characteristics.
When it comes to installation, air preheater tube installation requires a great deal of expertise and experience. Depending on the type and design of the air preheater, different installation procedures and instructions may be required. It is vital to follow all instructions provided for the individual air preheater set up.
Air preheater tubes are usually batched together in an air preheater. This type of design allows for maximum heat transfer efficiency. The hotter exhaust gases or exhaust stream will pass through these tubes and will be collected and directed to the inlet of the combustion chamber. The cooler air that has been preheated leaves the outlet of the combustion chamber and is then exhausted.
Air preheater tubes are normally connected by gaskets, nuts, and bolts. These connections must be checked and cleaned periodically to ensure efficiency and longevity of the preheaters. A series of air baffles are placed around the outside of the air preheater tubes for uniform air distribution.
Regular maintenance and cleaning is also an important part of proper air preheater tube operation. This helps to prevent the formation of dangerous buildup in the tubes that can cause corrosion or inefficiency. Maintenance and cleaning should be done on a regular basis and following the manufacturer’s instructions.
Air preheater tubes must also be inspected regularly and replaced if they become cracked, damaged or worn. This is because damaged or worn tubes can cause air bypass and reduce thermal efficiency of the air preheater. If inspection reveals that a damaged or worn tube is causing a decrease in efficiency, it should be replaced as soon as possible to ensure proper air preheating.
Air preheater tubes are an important component of the overall air preheating system and a responsible choice when choosing an air preheater set-up. By choosing the correct material, proper installation and regular maintenance, industrial users can be assured that their air preheater set-up will work at maximum efficiency. Furthermore, air preheater tubes also help to reduce fuel consumption, resulting in cost savings for the user.
