Hot Air Heaters
RCR Energy's indirect industrial air heaters come in a concentric shell (CC) and tubular (CT) designs. Fired on gas and oil these air heaters typically feed spray drying plants with hot, clean, process air and can operate to 430°C and output to 15MW.
Concentric Air Heater (CC models)
Indirect industrial air heater featuring a compact, strong and flexible design.
The Concentric Air Heater is a simple, low
maintenance design consisting of a series of concentric shell plates to
exchange heat and deliver clean process air at temperatures up to
420°C. Internal components are high temperature stainless steel
including corrugated
furnace walls to maintain air purity and hygiene whilst coping with
elevated
thermal stresses.
- Output range: 300 kW – 3,000 kW
- Temperature: up to 420°C
- Fuel: gas fired (special oil version on request)
Tubular Air Heater (TT models)
For larger duties this hot air heater offers exceptional reliability in critical applications
Tubular Air Heaters consist of a ceramic
lined combustion chamber followed by a fully stainless steel air-to-air heat
exchanger configured in an innovative wave-form tubular design to minimise
thermal stress across the heat exchanger. Flue gas recirculation is employed in
the combustion process to reduce NOx and to temper and accurately control the
heating temperatures ensuring long plant life despite arduous conditions. Very
high operating efficiencies are possible with optional inclusion of
recuperative air heater or economiser on exhaust of air heaters.
- Output range: 2 MW – 12 MW
- Temperature: up to 420°C
- Fuel: gas fired (special oil version on request)
