ICFB (INTERNAL CIRCULATION FLUIDIZED BED BOILER)
Stably burns fuels of various properties and shapes.
The ICFB is able to burn various types of waste and sludge, such as refuse-derived fuel including corrosive substances. It suppresses the generation of NOx by stable low-temperature combustion. It also reduces the corrosion of heat transfer tubes due to corrosive gas, and achieves high efficiency and high reliability.
- Circulates the bed material by the difference of air flow.
Divides the fluidized bed into a combustion cell and a heat recovering cell using a double partition wall and circulates the bed material internally by the difference of air flow.
- Stably controls the fluidized bed temperature.
The temperature of fluidized bed is stably controlled for various calorific value fuels, by suitably adjusting the heat absorption of in-bed heat transfer tubes.
- Reduces the corrosion of boiler tube due to corrosive gas.
Prevents corrosive gas from entering the heat recovering cell by a double partition wall and reduces the corrosion of boiler tube.
