Direct Fired Hot Air Generator

Product Details

In Direct Fired Hot Air Generator, the combustion chamber is enclosed in a concentric shell with suitable (refractory) lining. The fresh air from dynamically and statically balanced blower is fed to the chamber tangentially. The air envelopes the combustion chamber and absorbs the radiant heat from its surface and then mixes with completed combustion gases in a conical chamber. The hot air, thus generated is let out from hot air generator at controlled temperature to the process. Such heating systems have very high thermal efficiency with proper insulation.

Indirect Fired Hot Air Generator

Product Details

In Indirect Fired Hot Air Generator combustion is completed within the chamber. Hot gases, after complete combustion are then passed through Tube Heat exchanger, comprising of second & third pass. Fresh Air from atmosphere is fed onto the surface of combustion chamber through a statically & dynamically balance blower. The shape of passage ensures to form an envelope on the combustion chamber to extract maximum heat, thus higher heat transfer efficiency. The air continues to pass through outer surface of heat exchanger, gaining heat & is collected at the other end of hot air generator. The generation of hot air is within minutes of its start.
