Boiler reheating steam temperature control method, boiler, electronic equipment and storage medium

Abstract

The invention provides a boiler reheating steam temperature control method, a boiler, electronic equipment and a storage medium, and the method comprises the steps that firstly, a prediction override signal of the boiler is obtained, the prediction override signal is used for representing the operation condition of the boiler at the preset moment, and the preset moment is the moment after the current moment; then whether the predicted override signal meets a preset override condition or not is judged, and if yes, the opening degree of a flue gas baffle is adjusted according to the predicted override signal so as to control the reheating steam temperature in the boiler; otherwise, the actual steam temperature of the boiler is obtained through a first temperature sensor arranged in the boiler; a steam temperature difference value between the actual steam temperature and a preset steam temperature threshold value is calculated; according to the mode, the reheating steam temperature in the boiler is effectively controlled, the adjusting precision of the steam temperature of the boiler is improved, and steam temperature fluctuation is reduced.

Description

technical field [0001] The present application relates to the technical field of boiler control, in particular to a method for controlling the reheating steam temperature of a boiler, a boiler, electronic equipment and a storage medium. Background technique [0002] Reheat steam temperature control refers to controlling the outlet steam temperature of the reheater in the boiler to a given value. When the temperature of the reheat steam is low, the safety factor of the metal pipe strength will be reduced, and the heat cycle efficiency of the unit will be reduced. Commonly used adjustment methods include steam-steam exchanger method, reheat steam bypass method, tail flue gas recirculation method, tail split flue gas baffle method and swing burner method, etc. In these temperature adjustment methods Among them, the flue gas baffle has the advantages of safe and simple equipment, flexible control, no additional auxiliary power requirements, and the ability to achieve two-way te...

Problems solved by technology

[0004] However, the sluggish rate of flue gas adjustment is relatively large, and the simple actual steam temperature adjustment accuracy is low, and the adjustment is not timely, often resulting in excessive fluctuations in reheat steam temperature
