Description

Technical Field

[0001] This utility model relates to the field of boiler combustion technology, specifically to a boiler combustion device. Background Technology

[0002] With global economic development and population growth, the demand for energy continues to increase. Electricity, as a clean and efficient secondary energy source, plays a vital role in modern society. Power plants, as the primary sites of electricity production, need to continuously improve their power generation efficiency and supply capacity to meet the enormous demand for electricity. For example, in some rapidly developing economic regions, industrial production and residential electricity consumption are constantly rising, requiring power plants to increase power generation and ensure power supply through measures such as optimizing boiler combustion devices. A stable power supply is crucial for modern industry, commerce, and residential life. The efficient operation of power plant boiler combustion devices ensures that the boiler produces stable and continuous steam, which drives the steam turbine to generate electricity, providing a stable power output to the grid. For example, in places with extremely high requirements for power supply reliability, such as hospitals and data centers, a power outage could have serious consequences; therefore, power plants need to use advanced combustion device technology to ensure a stable power supply.

[0003] This utility model, disclosed in announcement number CN201348356Y, is an environmentally friendly and energy-saving boiler combustion device, including a furnace body with a coal feeding port and a slag removal port, and a furnace chamber inside the furnace body. The key feature is that an air inlet is located at the lower part of the furnace body, the coal feeding port is located at the top of the furnace body on its outer side, and a vertical coal storage bin is located around the upper part of the furnace chamber, with the lower part of the coal storage bin connected to the furnace chamber. This utility model has a reasonable structural design and significant energy-saving effect, solving the technical problems of energy waste and environmental pollution in existing technologies. It is an ideal environmentally friendly and energy-saving boiler combustion device. This boiler combustion device, when used with a boiler body, can be used to manufacture boilers suitable for bathhouses, hotels, and home bathing and heating. However, the structure of the aforementioned combustion devices is relatively simple, making it difficult to effectively observe the flame and fuel status. Therefore, we propose this boiler combustion device. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a boiler combustion device, including a combustion chamber 1:

[0024] A support frame 2 is provided on the upper surface of the combustion chamber 1, a recovery chamber 3 is provided at the lower front end of the combustion chamber 1, an observation structure is provided at the upper front end of the combustion chamber 1, a fuel chamber 9 is provided on the left side of the combustion chamber 1, and a delivery pipe 10 is provided at the right end of the fuel chamber 9, and the delivery pipe 10 is connected to the upper left side of the combustion chamber 1.

[0025] A filter rack 4 is installed in the middle of the combustion chamber 1, and multiple sets of filter holes are evenly opened on the surface of the filter rack 4. This can filter out small particles generated during combustion and facilitate the recycling of the small particles into the recovery chamber 3.

[0026] The observation structure includes an observation tube 5, which is fixedly installed on the upper part of the front surface of the combustion chamber 1. An observation window 6 is provided at the front end of the observation tube 5. Through the observation window 6, the operator can directly observe the flame status inside the combustion chamber 1. The color, shape, and stability of the flame can reflect the degree of combustion and efficiency. In addition to observing the flame, the operator can also observe the combustion status of the fuel inside the combustion chamber 1, such as whether the fuel is evenly distributed in the combustion area, and whether there is coking or carbon buildup. If local fuel accumulation or coking is found, it may affect the normal combustion process and may even cause equipment damage. By promptly identifying these problems through the observation window 6, corresponding measures can be taken, such as cleaning the combustion chamber 1 or adjusting the fuel delivery device, to ensure the smooth progress of the combustion process.

[0027] A scraper 7 is provided on the rear surface of the observation window 6, and a rotating block 8 is connected to the scraper 7 through the observation window 6. During the boiler combustion process, dust in the environment and small particles generated by combustion may adhere to the surface of the observation window 6. The scraper 7 can periodically or irregularly scrape away this dust and dirt to ensure that the observation window 6 always remains clear. In this way, the operator can accurately observe the situation inside the combustion chamber 1, such as the flame status and fuel combustion status, through the observation window 6, without making misjudgments due to the blurriness of the observation window 6.

[0028] The lower surface of the fuel tank 9 is designed with an inclined structure, and the lower end of the inclined structure is connected to the delivery pipe 10. The inclined structure allows the fuel to flow more smoothly to the delivery pipe 10 by its own gravity. When the fuel is in the fuel tank 9, gravity acts on the fuel, causing it to tend to move downwards. The inclined design provides a downward channel for the fuel, reducing the possibility of fuel accumulation and blockage in the tank. This helps to ensure that the fuel enters the delivery pipe 10 stably from the fuel tank 9.

[0029] A conveying rod 11 is installed inside the conveying pipe 10, and the upper end of the conveying rod 11 passes through the conveying pipe 10 and is connected to a drive motor 12. The drive motor 12 is fixedly installed on the upper end of the conveying pipe 10. The conveying rod 11 is set as a spiral structure, and the diameter of the spiral structure is the same as the inner diameter of the conveying pipe 10. During the rotation of the spiral structure, its spiral blades can push the fuel forward like a screw. Since the diameter of the spiral structure is the same as the inner diameter of the conveying pipe 10, the fuel is fully agitated and pushed in the conveying pipe 10 by the spiral blades, with almost no dead corners in the flow. This ensures that the fuel can be delivered from the fuel bin 9 to the combustion bin 1 in a relatively stable and continuous manner. Compared with the traditional smooth conveying rod 11 or simple pipeline conveying, more fuel can be delivered per unit time, thereby improving the fuel supply efficiency of the entire boiler system.

[0030] Working principle: Add fuel to fuel tank 9, turn on drive motor 12, and add fuel to combustion chamber 1 through conveyor rod 11 for combustion. Then, observe the combustion effect through observation component. After combustion is completed, the debris or fuel produced by combustion falls into recycling chamber 3 through filter frame 4 for recycling.
