A METHOD OF INCREASING THE HEATING RATE BY CONTROLLING THE OXIDANT CONCENTRATION AND THERMAL ENERGY IN THE CIRCULATING FLUIDIZED BED REACTOR AND CIRCULATING FLUIDIZED BED COMBUSTION SYSTEM USING THE SAME

摘要

An embodiment of the present invention provides a technique for minimizing the generation of air pollutants by increasing the temperature increase rate in a circulating fluidized bed reactor. The circulating fluidized bed reactor control method for increasing the temperature increase rate by controlling the oxidizing agent concentration and heat quantity according to an embodiment of the present invention includes a combustion furnace, a cyclone and a loop seal, and the fluidized sand includes a combustion furnace, a cyclone, a loop seal and a combustion furnace. In the circulating fluidized bed reactor control method for increasing the temperature increase rate by controlling the concentration and heat amount of an oxidizer that is heated as a whole by being cycled through sequentially, the oxygen concentration in the oxidizer gas supplied to the combustion furnace, the amount and flow of fuel supplied to the combustion furnace A first step of starting the combustion furnace according to the initial value of each of the circulation amount of yarn; a second step of deriving a target temperature reaching time, which is a time for the temperature of a portion of the combustion furnace to reach a preset target temperature, and deriving a reference value for a temperature increase rate of a portion of the combustion furnace; and a third step of controlling the circulation amount of the flowing sand and the oxygen concentration in the oxidizing agent gas according to the reference value of the temperature increase rate of one part of the combustion furnace.
