Three(3) Fuel Burner for Rotary Kiln
Any type of fuel-oil, gas or pulverized coal can be combusted in this burner. Mixed feeding of different fuels is also possible.
The burner consists of three concentric rings. In the center is an oil burner.Around it is a gas burner, and around the gas burner is a pulverized coal burner.Primary air is supplied between each burner.
| Capacity | 5～5,000 GJ/h |
|---|---|
| Applications | Calcination of cement, limestone, limestone mud Calcination of Alumina, Nickel ore, Iron ore pellet Incineration of waste materials |
Air Heater・Fired Heater
High Pressure/Enthalpy Intensified Combustor (High-pressure Hot Air Generator)
Constructed completely of metal, this combustor is designed for high pressure/highly intensified air generation.
- Pressure：MAX. 1.0 MPa
- Temperature：MAX. 1,000℃
- Combustor load：0.58MW/m3 at pressure of 0.5Mpa (depending on operating pressure)
This air generator can reach the maximum enthalpy condition within two minutes after ignition because of its all metal construction. Furthermore, there is no risk of solid matter dispersion into the slipstream because of its non castable refractories construction.
