Problems solved by technology

[0003] At present, the mechanical measurement method is used to detect the expansion of the boiler. Since the expansion of the boiler cannot be used in real time to judge the stress generated inside the boiler, it cannot effectively prevent the large stress inside the boiler.

Abstract

The invention discloses a boiler temperature change control method. The method comprises the steps that the main steam temperatures and the preset coal feeding amount of a boiler are obtained; the temperature change rate is calculated according to the main steam temperatures at different times; and the preset coal feeding amount is adjusted according to the temperature change rate. As large stress can be generated in the boiler due to too fast temperature rising and consequently boiler deformation and even major accidents are caused, the stress generated in the boiler is judged in real time according to the temperature change rate, the preset coal feeding amount is adjusted to control the temperature change rate of the boiler so as to enable the temperature of the boiler to rise stably, large stress is effectively prevented from being generated in the boiler, and the safety of the boiler in the temperature rising process is guaranteed. In addition, the invention discloses a boiler temperature change control device and a computer readable storage medium corresponding to the method, which have the specific effects as above.

Description

technical field [0001] The present application relates to the technical field of boiler detection, in particular to a control method, device and medium for boiler temperature change. Background technique [0002] Due to the large structure of the boiler, stress will be generated during the heating process. If the heating rate is too fast, a large stress will be generated between the internal structure of the boiler, causing deformation of the boiler, and even a major accident. The main reason for this kind of stress is that the metal expands with the change of temperature, and the expansion speed is too fast, which will generate greater stress. [0003] At present, the mechanical measurement method is used to detect the expansion of the boiler. Since the expansion of the boiler cannot be used in real time to judge the stress generated inside the boiler, it cannot effectively prevent the large stress inside the boiler. [0004] Therefore, it is an urgent problem to be solved...
