Abstract
A method for enhancing furnace efficiency of a fluidized bed boiler is provided. The fluidized bed boiler includes a boiler body for carrying out fuel combustion in a fluidized bed thereof; a fluidized gas inlet for inputting an oxygen-containing fluidized gas into the boiler body to fluidize a boiler bed and facilitate the fuel combustion; a steam outlet for outputting a steam resulting from the fuel combustion from the boiler body; and a flue-gas exhaust for emitting a flue gas resulting from the fuel combustion from the boiler body. The method includes steps of: detecting an oxygen concentration of the flue gas; feeding a portion of the flue gas back to the fluidized gas inlet; and dynamically adjusting a flow rate of the feeding fluidized gas according to oxygen concentrations of the flue gas and the feeding fluidized gas to achieve automatic control of the fluidized bed boiler.
