Abstract

The invention discloses a steam generator pressure adjusting-control method and apparatus based on a PID, and a storage medium. The method comprises the steps that in the low-pressure interval, the PID keeps the input power P0 constant till the steam pressure reaches the maximum value of the low-pressure interval; in the rising interval, the PID controls the input power P0 to be gradually increased till the steam pressure reaches the maximum value of the rising interval; in the keeping interval, the input power is controlled by the PID to achieve dynamic stability; and the low-pressure interval, the rising interval and the keeping interval are continuous in numerical value. Different gears are divided through the different pressure intervals, each gear is controlled based on the PID, stability and controllability of steam pressure are achieved, unnecessary steam losses are decreased, gas consumption is decreased, in addition, the steam pressure fluctuation is reduced, thus, impact to mechanical parts of a steam generator is reduced, and metal fatigue is relieved.

Description

technical field [0001] The invention relates to the technical field of steam generators, in particular to a PID-based steam generator pressure regulation method, equipment and storage medium. Background technique [0002] As the use of coal-fired boilers continues to be restricted by national policies, clean energy has been promoted and popularized across the country, among which natural gas has been widely used by virtue of its own advantages, so gas-fired steam generators are also becoming more and more popular, but At present, steam generators usually use pressure gauges and other methods to control the steam pressure, so the steam pressure is not constant during operation, and the fluctuation range is large, which cannot achieve the same steady-state effect as traditional heating equipment. Contents of the invention [0003] The purpose of the present invention is to at least solve one of the technical problems in the prior art, and provide a PID-based steam generator ...
