Air heating is a part and parcel of many industries. It is used in bakery, laundry, oil & gas, power, and other industries for different purposes. It all depends on the requisites of the industries. Customized designs are often used to serve the purpose. Air heating elements are generally designed and manufactured based on the specific requirements of an industry. From hospitality to heating big furnaces, air heaters are used as a part of the operations. Let us find out how the responsible team of engineers choose air heaters.
Things to look for in air heating systems
1. Knowing the process
Engineers first calculate
the amount of air to be heated and what temperature. The rate of heat transfer
will determine the equipment and industry needs. The atmosphere inside a
machine will also determine the rate of heat transfer. Hence, it is the prime factor
to choose the right heating elements for
the purpose.
2. Convection
Another important factor to
consider in the air heating process is whether the machine is using a steady
airflow or depending on the convection current. It all depends on the airflow
rate. A heating element will be chosen accordingly based on the amount of heat
to be passed to raise the temperature of a column of air passing through the
element. When the airflow is forced, the rate of heat transfer will be higher
than what is required to heat a stagnant air column. Checking the rate of
convection also becomes very necessary.
3. Applications
The application in an
industry will determine the type of air
heating elements required. It depends on what process the heated air will
serve. It can be used to maintain an ambient temperature inside a room or maybe
needed for industrial processes such as calcining, melting, drying, etc.
4. Performance of the heating elements
The performance of an air
heater needs to be calibrated according to the need of an industry. Customized
solutions are provided for meeting this particular need.
Final words
These are some of the
considerations when air heating elements
are chosen. Follow the parameters mentioned to get the best
solution.
