n industrial drying and heating systems, HAG typically stands for Hot Air Generator.
🔥 HAG – Hot Air GeneratorA Hot Air Generator (HAG) is an equipment that produces hot air by mixing fuel combustion gases with fresh air to supply controlled-temperature hot air to dryers, spray dryers, ovens, or other process equipment.
⚙️ Working PrincipleFuel Combustion: Fuels like diesel, furnace oil, gas, coal, or biomass are burned in a combustion chamber.
Heat Transfer: The heat from combustion is transferred to air either:
Directly (hot gases mix with air)
Indirectly (heat is transferred via heat exchangers)
Hot Air Outlet: The system delivers hot air at temperatures from 100°C to 800°C, depending on the process needs.
| Type | Description | Max Temperature |
|---|---|---|
| Direct Fired | Combustion gases directly mix with air; simple and efficient. | ~800°C |
| Indirect Fired | Heat is transferred through a heat exchanger; clean hot air; no contamination. | ~400–500°C |
