Embodiment 1

[0030] image 3 Shown is the block diagram of the combustion control device in the first embodiment of the present invention. The principle of the combustion control in this embodiment is: when the natural gas is completely burned, the natural gas flow rate and the air flow rate meet a certain flow ratio relationship. When the natural gas flow rate is constant, this flow ratio is based on To control the air flow, obviously, those skilled in the art to which the present invention belongs can easily think that the natural gas flow can also be controlled according to the flow ratio when the air flow is constant. This can be achieved without any creative work. It also belongs to the original Invention protection scope.

[0031] Combine figure 1 As shown, the combustion control device in this embodiment includes a natural gas flow acquisition device 3 and an air flow control device 4. The natural gas flow acquisition device 3 may be a flow meter for acquiring the natural gas flow value...

Embodiment 2

[0044] Figure 5 Shown is the block diagram of the combustion control device in the second embodiment of the invention, combined with figure 1 As shown, in this embodiment, the natural gas flow is not controlled by the working temperature in the combustion furnace, but the natural gas flow is controlled by a single loop PID control, so that the natural gas flow is equal to the required natural gas flow (ie, the preset natural gas flow).

[0045] First, the required natural gas flow is sent to the natural gas flow control device 6 through an input device such as a keyboard or touch screen. The natural gas flow acquisition device 3 acquires the natural gas flow and sends the acquired natural gas flow to the natural gas flow control device 6, and the natural gas flow control device 6 It is compared with the required natural gas flow rate. If the two are not equal, the natural gas flow rate adjustment device 5 is controlled according to the corresponding control algorithm to adjust the...

Abstract

The invention provides a burning furnace, a burning control method and a burning control device. The burning control device comprises a natural gas flow acquisition device and an air flow control device, the natural gas flow acquisition device is used for acquiring a natural gas flow value and transmitting the acquired natural gas flow value to the air flow control device, and the air flow control device is used for receiving the natural gas flow value transmitted by the natural gas flow acquisition device and controlling air flow according to the preset flow ratio of natural gas to air. The burning control method includes the steps: acquiring the natural gas flow value; and controlling the air flow according to the preset flow ratio of the natural gas to the air. The burning furnace comprises the burning control device. The problems of pollution and waste caused by incomplete burning of the natural gas due to air deficiency are solved.

Description

Technical field [0001] The invention relates to the technical field of combustion furnace control, in particular to a combustion furnace and a combustion control method and device. Background technique [0002] The natural gas from the natural gas main pipe is adjusted by the pressure regulating device to have a certain pressure, and then enters the combustion furnace through the natural gas feed passage to provide fuel for the combustion of the combustion furnace. Among them, the natural gas flow rate on the natural gas feed path is related to the pressure of the natural gas. The oxygen required for the combustion of natural gas in the combustion furnace is provided by the air blown into the combustion furnace by a fan. [0003] For a long time, the combustion control of the combustion furnace has been problematic, especially the incomplete combustion of natural gas caused by insufficient air causes pollution and waste, and may even cause the combustion furnace to extinguish. Su...
