Components Of The CFB Boilers

The main components of the circulating fluidized bed boiler include the combustion system, steam water system, control system, and auxiliary system.

 

The main components of the circulating fluidized bed boiler include the combustion system, steam water system, control system, and auxiliary system.

 

 

The combustion system is responsible for the combustion of fuel and the release of heat, the steam water system is responsible for the heating, evaporation, and superheating of water, the control system is used for monitoring and regulating the boiler, and the auxiliary system is responsible for the normal operation and maintenance of the boiler.

 

 

The combustion system mainly includes furnace, burner, air preheater, flue and steel frame. The fuel burns in the furnace, releasing heat energy. The air preheater improves combustion efficiency, the flue is used for exhaust gas discharge, and the steel frame supports the entire furnace body.

 

 

The steam water system includes economizers, evaporative heating surfaces, superheaters, etc. After being preheated by the economizer, the feedwater enters the boiler and is converted into steam on the evaporation heating surface. The superheater heats the steam to the required temperature. This system ensures efficient conversion of water into steam for use in turbines.

 

The control system consists of various instruments and automatic control devices, which are used to monitor and adjust the operating status of the boiler in real time, ensuring safety and efficiency.

 

 

The auxiliary system includes soot blowing, slag removal, water treatment, etc., which ensure the long-term stable operation and daily maintenance of the boiler.
