China supplier internally power plant circulating fluidized bed hot water boiler
Introduction:
Circulating fluidized bed is of low-temperature combustion, therefore, nitrogen oxides emissions of such boiler is much lower than that of coal-powder boiler, and such boiler could directly desulfurized during combustion process. Circulating fluidized bed boiler with high desulfurization rate is economical.
Circulating fluidized bed boiler could adopt various coal types and has high combustion efficiency, which is especially suitable for low quality, low calorific value coal.

Description:
HETG boilers are efficient, energy saving and environmental friendly, which can help power plants actualize low pollutant emission based on their advanced technology and reliable running.
High efficiency: combustion efficiency 96~99%, carbon content in ash only about 2%, efficiency of boiler reaches 85%.
- Suitable for various kinds of coal.
- Load can be adjusted in the range of 25%~110%, average 5% in one minute.
- Clean combustion and environment friendly.
- Use lime stone mixed into the fuel for desulfuration, rate up to 84%.
- NOx emission capacity can be controlled to 150ppm or less.
- Ash with low carbon content can be used for cement or construction materials.
The accessory of power plant high thermal efficiency CFB boiler
1. Water wall panels: placed aroud the boiler combustion chamber
Boiler water walls are membrane walls that are made of tubes welded together with or without a strip of metal in between. These walls form the enclosure of the coal combustion chamber. Water wall tubes are also referred to as the evaporator section; they contain water mostly in liquid form which gradually evaporates as it rises in the boiler.
2. superheater and economizer
Economizer, header, air preheater in CFB steam boiler for power plant.
3. Rotary air preheater
Rotary Air preheater recovers the heat from the flue gas and transfers the same to the combustion air to the boiler thus reducing the fuel consumption of the boiler.
The efficiency of Rotary Air preheater is very high compared to the Tubular air preheater.
Air preheater rotor is divided into compartments in which the heating elements are packed. Heating elements in the Air preheater plays a major role for the heat transfer from the flue gas to the combustion air.
Application:
CFB steam boiler is widly used in power station or power plant.
