Indirect fired Hot Air Generators

An indirect fired hot air generator is a type of industrial heating equipment designed to produce hot air by indirectly heating it through a heat exchanger. The heat exchanger is typically separated from the combustion chamber, ensuring that the combustion products do not come into direct contact with the air being heated. This design provides a clean and controlled heating process, making it suitable for various industrial applications.

Here are the key components and principles of an indirect fired hot air generator:

1. Combustion Chamber:

The combustion chamber is where the fuel is burned to generate hot gases. Common fuels include natural gas, diesel, propane, or other liquid or gaseous fuels.

2. Burner:

The burner is responsible for the combustion of the fuel. It releases energy in the form of heat, which is transferred to the heat exchanger.

3. Heat Exchanger:

The heat exchanger is a critical component that separates the combustion gases from the air to be heated. It transfers heat from the hot gases to the air indirectly, ensuring the two do not mix.

4. Air Circulation System:

A fan or blower circulates air through the heat exchanger, where it absorbs heat from the combustion gases. The heated air is then directed to the desired location for industrial processes.

5. Temperature Control:

Indirect fired hot air generators often include temperature control mechanisms to maintain a consistent and controlled air temperature. This ensures that the heated air meets the specific requirements of the industrial process.
