Efficiency of circulating fluidized bed boilers
Thread Content
What is the efficiency of a conventional circulating fluidized bed boiler?
Around 85-90, depending on the specific type of coal
The working principle of the circulating fluidized bed results in low efficiency, around 80% only, which is lower than that of coal powder boilers; however, it is more environmentally friendly, which is why it has still been widely adopted.
Internationally, circulating fluidized bed boilers are mostly used for burning waste, while in China they are primarily used for burning coal gangue. The current 300MW ultra-supercritical boilers can also achieve a efficiency of 90%
The efficiency of circulating fluidized bed boilers is higher than that of coal powder boilers, around 85.
