[0002] In the energy field, boilers are an important energy conversion equipment and are widely used in various industrial production processes. The combustion equipment of the boiler is its core component, which directly affects the boiler's combustion efficiency, energy utilization and environmental emissions. Traditional fixed combustion equipment is often designed to efficiently burn only one specific fuel. When the type of fuel changes, the combustion efficiency will drop significantly. In addition, these devices usually do not have an automatic slag removal function, and the ash produced by combustion needs to be cleaned manually, which not only increases labor costs, but may also affect the combustion effect due to untimely cleaning.

[0003] Especially when using coal, biomass or other solid fuels, the amount of ash produced is large. If it is not cleaned in time, it will seriously hinder the combustion, reduce thermal efficiency, and may even cause damage to the equipment. At the same time, traditional fixed combustion equipment is often extensive in terms of air distribution and cannot be finely adjusted according to the combustion conditions of the fuel, which not only affects the stability of combustion, but also limits the improvement of combustion efficiency.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] In this fixed combustion equipment with automatic slag removal, the primary air distribution duct and adjustable damper design of the equipment enable the equipment to adapt to different types of fuels. By adjusting the damper, the amount of air in the combustion process can be accurately controlled to ensure the full combustion of various fuels. This design greatly improves the combustion efficiency of the fuel and also expands the applicable range of the equipment to fuels.

[0015] Secondly, the air distribution plate design inside the equipment makes the air more evenly distributed inside the pot, further improving the combustion efficiency of the fuel.

[0017] In addition, an observation door is set up on the side of the equipment, which is convenient for operators to observe the combustion situation at any time and adjust the equipment parameters in time to ensure the safety and efficiency of the combustion process.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides a fixed combustion device with automatic slag removal, such as Figure 1-Figure 3 As shown, it includes a pot body 1, a primary air distribution duct 2 is installed at one end of the pot body 1, an adjustable damper is installed on the inner side of the primary air distribution duct 2, a plurality of air equalizing plates 7 are installed inside the pot body 1, a bottom plate 6 is installed at the bottom of the pot body 1, a secondary air distribution duct 3 is installed on the upper part of one end of the bottom plate 6, the inner side of the secondary air distribution duct 3 is aligned with the ash slag on the upper part of the bottom plate 6, a baffle 5 is installed on the upper part of one end of the bottom plate 6 away from the secondary air distribution duct 3, the baffle 5 is inclined, and a slag remover interface 10 is provided at the baffle 5 of the bottom plate 6 close to the baffle 5. Different solid fuels are burned on the combustion equipment, and a primary blower blows the air required for combustion into the air duct through the primary air distribution duct 2. An adjustable damper is provided inside the primary air distribution duct 2. After the wind comes out, it can pass through the air equalizing plate 7 to ensure that each position of the combustion equipment can get reasonable Air distribution can ensure the full combustion of the fuel. At the same time, the size of the fire can be adjusted, which greatly improves the combustion efficiency and makes the combustion adjustable and controllable, which completely changes the extensive combustion mode of the previous fixed combustion equipment. The air door is arranged at the air outlet end of the primary air distribution pipe 2, and a sliding connection is adopted. One side of the air door passes through the outer wall of the pot body 1 and is equipped with a handle. The air intake size can be adjusted by manually driving the air door to slide horizontally. After the ash after the fuel is burned falls on the bottom plate 6, the secondary blower blows air into the combustion equipment through the secondary air distribution pipe 3 at the rear, and the secondary air can be pressurized through the secondary air ejector pipe 4, so that the secondary air entering the combustion equipment becomes high-pressure wind, so that the ash inside the combustion equipment can be blown to the front. A baffle 5 is arranged at the front to allow the ash to fall smoothly into the slag remover.

[0025] In this embodiment, the outer ends of the primary air distribution pipe 2 and the secondary air distribution pipe 3 are both connected to a primary blower for blowing air into the equipment.

[0026] Specifically, a plurality of air holes are evenly opened on the surface of the air distribution plate 7 to ensure even distribution of the air after it passes through.

[0027] Furthermore, the bottom of the slag remover interface 10 is connected to the external slag remover material port to facilitate the ash and slag to fall into the slag remover.

[0028] Furthermore, a plurality of observation doors 8 are provided on the side of the pot body 1 to facilitate observation of the interior of the device from the outside.

[0029] Furthermore, lifting ears 9 are installed on the outer walls at both ends of the pot body 1 to facilitate the lifting and transfer of the equipment.

[0030] Furthermore, the spacing between adjacent wind balancing plates 7 is 100 mm to ensure uniform distribution of the bees.

[0031] Furthermore, a secondary air ejector pipe 4 is vertically connected to one side of the secondary air distribution pipe 3 , and the air outlet of the secondary air ejector pipe 4 is directly opposite to the upper part of the bottom plate 6 and is evenly and evenly spaced, so that the ash on the bottom plate 6 can be completely blown away.

[0032] When the fixed combustion equipment with automatic slag removal of the utility model is used, the primary air distribution is mainly carried out through the primary air distribution pipe 2. The adjustable damper installed inside the air distribution pipe can control the air intake to ensure the full combustion of the fuel. The air distribution plate 7 inside the pot body 1 ensures that the air is evenly distributed, making the combustion more uniform. The secondary air distribution pipe 3 is combined with the secondary air ejector pipe 4 to generate high-pressure wind for automatically cleaning the ash and slag that fall on the bottom plate 6. The ash and slag then smoothly fall into the slag removal machine interface 10 through the baffle plate 5 to achieve automatic slag removal.

[0033] First, put the fuel into the pot body 1, then start the primary blower to blow an appropriate amount of air into the pot body 1 through the primary air distribution pipe 2. At this time, the operator can control the air intake and combustion intensity by adjusting the adjustable damper on the inner side of the primary air distribution pipe 2 according to actual needs. The air passes through the air distribution plate 7, and the air vents evenly opened on these air distribution plates 7 ensure that the air can be evenly distributed to various parts of the pot body 1, so that the fuel can be fully burned. A spacing of 100mm is maintained between adjacent air distribution plates 7 to further ensure the uniform distribution of wind. The ash produced by combustion will fall on the bottom plate 6. At this time, the secondary blower is started to blow high-pressure air into the pot body through the secondary air distribution pipe 3 and the secondary air ejector pipe 4. The air outlet of the secondary air ejector pipe 4 is directly opposite to the upper part of the bottom plate 6, and the high-pressure wind blows the ash on the bottom plate 6 to the baffle 5. Since the baffle plate 5 is tilted, the ash will slide down the baffle plate 5 to the slag remover interface 10, and fall into the external slag remover from the interface, thereby completing the automatic slag removal process. During the entire working process, the operator can observe the internal combustion situation at any time through the observation door 8 opened on the side of the pot body 1, and adjust the air door and other parameters as needed to ensure the stability and efficiency of combustion.
