METHOD FOR CONTROLLING TEMPERATURE DEVIATION OF REHEATED STEAM IN POWER GENERATION BOILER

摘要

The present invention provides a method for controlling a temperature deviation of reheated steam in a power generation boiler, which automatically adjusts an opening angle of an air conditioner for each burner to be deflected according to a temperature deviation of reheated steam to ease the temperature deviation in a timely manner, thereby reliably operating a power generation boiler. Air conditioners of which the number is the same as burner columns are arranged on the upper portions of burner terminals. The opening angle of the air conditioners is controlled. When the amount of air increases, the method lowers the temperature of steam while the temperature of combustion gas in a corresponding part relatively lowers. Reversely, when the amount of air decreases, the method raises the temperature of steam while the temperature of combustion gas in the corresponding part relatively rises. Therefore, the method for controlling a temperature deviation of reheated steam in a power generation boiler automatically adjusts an opening angle of the air conditioners to be deflected by burner column according to the temperature deviation of reheated steam, thereby reliably maintaining the temperature deviation.;COPYRIGHT KIPO 2020
