Description

Technical Field

[0001] This application relates to the field of gasifier technology, and more specifically, to a gasifier preheating burner. Background Technology

[0002] Currently, the ignition process of the preheating burner in a gasifier generally relies on manual operation. Operators must manually pull out the ignition gun head to light it and then send it into the gasifier.

[0003] During this process, if the negative pressure inside the gasifier becomes unstable, it can easily lead to backfire, causing burns to operators and even serious safety accidents. In addition, manual ignition is not only inefficient, but also makes it difficult to accurately control the timing of ignition and changes in furnace pressure. Even if the operator adjusts the negative pressure in advance and stands on the side of the furnace opening to operate during ignition, the insufficient precision of the observation hole will prevent the operator from clearly and accurately observing the combustion status inside the furnace and making it difficult to grasp the burner ignition status in time, which can easily lead to ignition failure. Summary of the Invention

[0004] The purpose of this application is to provide a gasifier preheating burner that can solve the technical problems mentioned in the background art.

[0005] This application provides a gasifier preheating burner, including a preheating burner housing disposed on and connected to the gasifier. The preheating burner housing is provided with an ignition assembly and a fuel gun. The lower nozzle of the fuel gun extends into the gasifier. The ignition assembly is used to ignite the fuel sprayed from the fuel gun. The preheating burner housing is provided with a flame monitor for monitoring the flame. An air inlet is provided on one side of the preheating burner housing.

[0006] Furthermore, the ignition assembly includes a continuous lamp and an ignition rod. The continuous lamp is fixed on the preheating burner housing, and the ignition port of the continuous lamp extends into the gasifier. The ignition rod is fixed inside the continuous lamp, and the fuel inlet and air inlet of the continuous lamp are both located outside the preheating burner housing.

[0007] Furthermore, the fuel gun is fixed to the preheating burner housing, and both the fuel inlet and air inlet of the fuel gun are located outside the preheating burner housing.

[0008] Furthermore, the flame monitor includes a camera and a back-end control display. The camera is fixed on the preheating burner housing and is electrically connected to the back-end control display.

[0025] like Figure 1 and Figure 2As shown, this application provides a gasifier preheating burner, including a preheating burner housing 1 mounted on and connected to the gasifier. The preheating burner housing 1 is equipped with an ignition assembly 2 and a fuel gun 3. The lower nozzle of the fuel gun 3 extends into the gasifier. The ignition assembly 2 is used to ignite the fuel sprayed from the fuel gun 3. The preheating burner housing 1 is equipped with a flame detector 4 for monitoring the flame. An air inlet 5 is provided on one side of the preheating burner housing 1. Specifically, fuel is transported into the gasifier through the fuel gun 3. The lower nozzle of the fuel gun 3 extends to a suitable position in the gasifier to spray fuel. The ignition assembly 2 ignites the fuel when it is sprayed, causing it to burn and thus generating a flame in the gasifier, achieving preheating of the gasifier. The flame detector 4 is used for real-time monitoring. The flame status is monitored so that operators can understand the combustion situation, detect abnormalities in a timely manner, and take corresponding measures. An air inlet 5 is provided on one side of the preheating burner box 1. The air inlet 5 is connected to the fan through a pipe. Air enters the preheating burner box 1 through the air inlet 5 and then enters the gasifier, providing the necessary oxygen for fuel combustion, so that the fuel can burn completely. The ignition component 2 can reliably ignite the fuel sprayed from the fuel gun 3, ensuring a smooth start-up of the combustion process. At the same time, the flame monitor 4 monitors the flame status in real time and can provide timely feedback information, which is convenient for adjusting and controlling the combustion process to ensure the stability of the flame. The setting of the flame monitor 4 can detect abnormal flame conditions in a timely manner, so that operators can take timely measures to avoid safety accidents.

[0026] like Figure 1 As shown, the ignition assembly 2 includes a continuous lamp 21 and an ignition rod 22. The continuous lamp 21 is fixed on the preheating burner box 1, and the ignition port of the continuous lamp 21 extends into the gasifier. The ignition rod 22 is fixed inside the continuous lamp 21. The fuel inlet and air inlet of the continuous lamp 21 are both located outside the preheating burner box 1. The continuous lamp 21 introduces fuel and air through the fuel inlet and air inlet located outside the preheating burner box 1, respectively. After the fuel and air are mixed inside the continuous lamp 21, the ignition rod 22 is energized to generate a spark to ignite the mixed fuel. The presence of the continuous lamp 21 provides a stable ignition source for the ignition of fuel in the gasifier. Compared with the use of a single ignition device such as the ignition rod 22, the continuous lamp 21 burns continuously and can quickly ignite the fuel each time the fuel gun 3 sprays fuel, which greatly improves the success rate and reliability of ignition and reduces production interruptions or safety hazards caused by ignition failure.

[0027] like Figure 1As shown, the fuel gun 3 is fixed on the preheating burner housing 1. The fuel inlet and air inlet of the fuel gun 3 are both located outside the preheating burner housing 1. Setting the fuel inlet and air inlet outside the preheating burner housing 1 facilitates connection to the fuel supply system and air supply system respectively. Fuel enters the fuel gun 3 through the fuel inlet located outside the preheating burner housing 1, and air enters the fuel gun 3 through the air inlet located outside the preheating burner housing 1. The purpose of the air entering is to mix with the fuel at a suitable location to achieve a good combustion effect.

[0028] like Figure 2 As shown, the flame monitor 4 includes a camera 41 and a back-end control display (not shown in the figure). The camera 41 is fixed on the preheating burner box 1 and is aimed at the flame area inside the gasifier. The camera 41 is electrically connected to the back-end control display, and the signal can be transmitted over long distances. Therefore, remote monitoring can be achieved. Operators do not need to observe the flame directly on site, but can monitor it in the control room far away from the gasifier, which improves the convenience and safety of operation.

[0029] like Figure 1 As shown, the flame monitor 4 also includes an infrared temperature monitor 42 (not shown in the figure). The infrared temperature monitor 42 is fixed on the preheating burner box 1 and is electrically connected to the back-end control display. The infrared temperature monitor 42 can accurately measure the flame temperature in a non-contact manner and can provide accurate flame temperature data in real time, which helps operators to keep abreast of the temperature changes in the gasifier. If sudden cooling or heating occurs, it can provide timely warnings to the operators.

[0030] like Figure 1 As shown, an air inlet 5 is equipped with an air regulating damper 6, which can flexibly adjust the amount of air entering according to the fuel supply and actual combustion conditions. This ensures that the fuel and air achieve the optimal mixing ratio, promotes complete combustion, improves combustion efficiency, reduces fuel waste and pollutant emissions from incomplete combustion, helps maintain the stability of the combustion process, and prevents unstable phenomena such as flame flickering, backfire, and flameout caused by excessive or insufficient air, thus ensuring the normal operation of the gasifier.

[0031] like Figure 2 As shown, the top of the preheating burner housing 1 is provided with a transparent observation hole 7. When maintaining and repairing the preheating burner, the transparent observation hole 7 provides a convenient observation window. Maintenance personnel can use the transparent observation hole 7 to view the internal structure of the burner and the wear of its components, which helps to accurately determine the cause of the fault and formulate a reasonable maintenance plan.

[0032] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
