Embodiment Construction

[0045] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0046] figure 1 According to an exemplary embodiment, a flow chart of a method for controlling the operation of a gasifier is shown to solve the problem of potential safety hazards caused by interlocking and sequential control that exist at the same time when the gasifier is running, which will cause interlocking and sequential control to contradict each other technical problems. Such as figure 1 , the method includes:

[0047] S11, before executing each step in the start-up procedure or shutdown procedure, confirm that the operating parameters of the gasifier meet the sequence control conditions corresponding to the step.

[0048] S12, sequentially contr...

Abstract

The present disclosure relates to a method, a device and a gasifier for controlling the operation of a gasifier, which are used to solve the problem of potential safety hazards caused by interlocking and sequential control in the related art when the gasifier is running at the same time, causing the interlocking and sequential control to contradict each other. technical problems. The method for controlling the operation of the gasifier includes: before executing each step in the start-up or shutdown procedure, confirming that the operating parameters of the gasifier meet the sequence control conditions corresponding to the step; sequentially controlling the order of the valves used in the step Action and in this step, monitor in real time whether the operating parameters of the gasifier meet the corresponding interlocking conditions of this step; when it is detected that the operating parameters of the gasifier meet the corresponding interlocking conditions of this step, switch to interlocking control of this step The action of the valves used in the sequence control jumps to the steady state of the stop step, so that the final switch state of the valves used in this step is consistent with the final switch state of the valves used in the stop step according to the sequence control.

Description

technical field [0001] The present disclosure relates to the field of gasifiers, and in particular, to a method and device for controlling the operation of a gasifier, and the gasifier. Background technique [0002] During the start-up process of the coal gasification device, it is necessary to ignite, heat up, increase the pressure, and feed coal. Among them, the coal feeding process cannot be realized manually by the operator, so it is necessary to use sequential control (that is, sequence control) to realize coal feeding, and it is also necessary to protect the operation process of the coal gasification device through an interlocking system. [0003] Because interlocking is to issue commands to multiple valves at the same time to allow multiple valves to execute commands, and there is no need to detect valve feedback. The sequence controller must detect the feedback from the valve. If the response is not received, the sequence controller will have to wait before issuing ...
