Coal Fired Circulating Fluidized Bed (CFB) Boilers

Coal Fired CFB Boiler

Circulating fluidized bed boiler is a kind of steam generating device that uses gas-solid fluidization technology to realize efficient combustion of fuel. During operation, the fuel and a large amount of inert bed material are held up by the high-speed gas flow in the furnace chamber, presenting a fluid-like fluidization state, so that the fuel and air are fully mixed and a violent combustion reaction occurs. At the same time, through the cyclone separator and other equipment to separate the solid particles in the high temperature flue gas, through the return device back to the bottom of the furnace chamber, to realize the cycle of combustion.

This unique design combines fluidized bed combustion technology, solid particle recovery and recycling technology, and a variety of auxiliary equipment to efficiently convert the chemical energy in the solid fuel into steam energy. Circulating fluidized bed boilers play a key role in meeting the world's growing energy demand. Their unique performance makes them the preferred choice for many industrial and power generation applications, especially under conditions that are difficult for conventional boilers to handle.

Advantages Of Circulating Fluidized Bed Boilers

Superior Fuel Adaptability

The circulating fluidized bed boiler is capable of burning a wide variety of fuels, covering fuels with different calorific values, types and characteristics. Moreover, it is highly resistant to fuel fluctuations and other disturbances, and remains a reliable choice when fuel quality is unstable.

Low Emission Environmental Characteristics

By virtue of its near-complete combustion process, the circulating fluidized bed boiler produces emissions that are among the lowest in the industry. Its ability to control NOx, SOx, CO and TOC emissions makes it an environmentally friendly energy converter that can easily meet stringent environmental regulations.

High Efficiency Operation

The circulating fluidized bed boiler requires less excess air to operate, a feature that significantly improves its operating efficiency. In addition, it has a high burnout rate and excellent load-following capability, maintaining stable operation even under changing load conditions.

Reliable And Durable Design

The reliable design of the circulating fluidized bed boiler ensures its high availability and long service life, reducing the need for frequent replacement and maintenance and, in the long run, lowering the cost of use and maintenance workload.
