However, the manual control is mainly adjusted by the operator watching the flame, which is not only rough, but also has poor real-time performance, and the control effect of different personnel is different, which is highly dependent on the operator. Many kiln combustion-supporting air is always at a certain flow value, and it is rarely adjusted.

The embodiment of the invention provides a roller hearth kiln atmosphere control method and device and a storage medium, and relates to the technical field of engineering control. The method comprises the following steps of acquiring fuel gas flow and fuel gas heat value of a current roller hearth kiln; establishing the corresponding relation between actual air flow and the fuel gas heat value; obtaining the actual air flow on the basis of the fuel gas heat value and the corresponding relation to obtain an air-fuel ratio, wherein the air-fuel ratio is the ratio of the actual air flow to the fuel gas flow; obtaining a current kiln atmosphere, and obtaining adjustment information according to the current kiln atmosphere and the air-fuel ratio so as to adjust the supply amount according to the adjustment information, so that the atmosphere of the roller hearth kiln is kept stable. According to the roller hearth kiln atmosphere control method and device and the storage medium, the atmosphere is adjusted according to the air-fuel ratio, so that the fuel gas flow and the actual air flow are kept in a certain proportional relation, and the atmosphere of the roller hearth kiln can also be kept constant under the condition that the fuel gas heat value fluctuates. The method has the advantages of simplicity, high control precision and low cost.
Description
technical field [0001] The invention relates to the technical field of engineering control, in particular to a roller kiln atmosphere control method, device and storage medium. Background technique [0002] Kiln atmosphere mainly refers to the content of gas components such as oxygen, carbon monoxide, and hydrogen generated during gas combustion. The atmosphere control of industrial kilns is not only an important factor to ensure product quality, but also a key link in energy saving, environmental protection and production cost reduction. [0003] Because it is difficult to control the thermal parameters of industrial kilns, most enterprises usually use zirconia analyzers to measure the oxygen content in flue gas as the control target to adjust the combustion air volume to form an oxygen-modulated air supply control system. However, since the working temperature of the zirconia flue gas analyzer is about 700°C, and the temperature of the firing zone of the ceramic roller ki...
