Internal Circulation Fluidized Bed Boiler
Stably burns fuels of various properties and shapes.
The Internal Circulation Fluidized Bed Boiler 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.
